.
- from memory , there are something like 3 to 4 threads here addressing the issue of Guhl's ECU flash mod. Guessing that there are quite a few owners interested to make the jump.
- iirc , the mod was done by Guhl together with Fred Harmon (of the other forum fame) and the two of them are perhaps the best persons to answer/address questions on it,
- afaik , neither Guhl nor Fred are in this forum to answer your queries.
- perhaps those who are really serious about this should just post a thread over there and get responses from the horses' mouth , so to speak.
.
- personally , am very keen and would like to see a tentative list of persons interested in the mod so that a scout party can be sent out to Guhl to find out what sort of a deal can be had :
.
- Yes , I am keen !

And I am Jim....Oh, and I'm interested so add me to the list for an 08 bike.
-
Add me to the list, and I'm Conrad.
-
The name of this topic should be changed to indicate it is a group buy thread.

I am Chris and I am interested in a group buy.

Group buy, group buy,
I am in, bombsquad 1201.
Add me to the list.
-
I'm the one who asked for a group buy first, so count me in...
-
I've been thinking about it also so yes I'm interested
-
I don't go over to the other forum. How about a quick info about what this mod will accomplish.
Is it for those with aftermarket exhaust or will it work with OEM exhaust?
Will it improve fuel economy? Fuel is getting going up fast!
Will it affect warranty work on the bike?
-
I would also be interested....
-
I'm interested, based on the price that can be negotiated.
(2011)
-
I'm interested.

$64,000 question: Has anybody called Don Guhl? This might be a moot point.

+1.. I am interested either way, a discount would push me to do it sooner rather than later...

Neither do I....
From what I understand the reflash makes things larger..at least, that's what I've been told.

WHERE is this OTHER Forum ???????????????
OH yeah I use to go there ...
-
Well, I might be interested, depending on the discount. I am kinda on the fence, still.

Got any pictures of YOU on the fence , I could see Kitty up there and I understand shortpeoplehavenobody But I'd love to see you on a chain link fence ::)
It's only money and you can't take it with you ;)
POWER is a BONITA thing
I'm a thrill JUNKY

So is riding on the back of a fire engine whilst holding on to the rail with lights and sirens wailing....rather enjoyed that time of my life...sigh.
-
I'm in for the group buy, I've been waiting to see if this is going to as I'm going either way.
-
I became a Volunteer firefighter as soon as I turned 18yr old. in NY old town with old wood houses free beer ;D life was good.
I believe teenagers should be forced into some type of civic duty, builds character.
Guhl does not give a break to motorcycle shops, I asked a place in town that has a dyno and the owner has a new ZX14 that he drag races , I thought I'd let him make a little money and he said to send it in myself because Guhl would not give him any type of discount, tight wad if you ask me.
I race Merc outboards and my motor builder plays with the ECUs #s , we also have a screw that we lean or richen up depending on out side temp , humidity , elevation at the race site.
If it was not for Traction control I would have done fly removal , oxygen sensor deal , but in the summer time our roads are wet all the time and the traction control works great.

He has separate maps from what I understand. Fuel economy will suffer slightly, but you can always use your ECO feature if you have a 10+ C14, as this map is unaffected. As with any modification, Kawasaki would have to prove that the mod was the reason for whatever warranty claim you should happen to make. It makes more power lower down from idle onwards, especially helpful when 2 up riding. Guys have had this flash for a couple of years now and no problems have been reported.
I hit both sites, as I am a COG member. Both sites are great for information. This site is and has always been my favorite for the less restrictive moderators, and the fun and camaraderie that goes with it. I will be looking at this mod for the summer, when I'm in Guhl country. I will have to go there to beat the tax/duty man in Canada. Only a 8 hrs. drive, and the COGGERs are having a spring meet up near by. A slip on will set me back at least that much, a full system and a programmer would be more.
A group buy would be great! So I would be interested.
-
I would be interested also. Anyone making contact to see if this is do-able?
-
Well, Mr. Pistole started this and hasn't chimed back in yet. Not sure what's the status at the moment... I do know that I'm not going over to the other forum... For those of you that do swing both ways, is there a start of a group buy over there?
I've sent a note to Don to ask if he's willing to do a group discount. I'll let you know what comes back.
Nothing yet...
-
I would be interested as well.
-
I live on both forums and if its any help to some I've had the flash by Guhl done on my 2010.
Whiles its not a Turbo, or Full exhuast system....it is a huge improvement for just a software/map tweak. More torque/power down low, comes on smoother and more linear. On some well known roads I find I don't have to gear down to 2nd on certain corners anymore and can still power out, same goes for the track. Asfor 2 Up riding, I've found the bike to be far more responsive.
-
WHERE is this OTHER Forum ???????????????
OH yeah I use to go there ...
same here.....LOL ;D
Depending on how it effects my warranty I might be interested.. :o
-
How they gonna know? Besides, we've had many a rider pull the flies and I haven't heard any negative dealer feedback on that...yet. I think this is a low risk option, myself.

The re-flash opens the flies sooner and farther open, kind of like removing them without removing them. It also changes the fuel map slightly. They can remove the top speed limiter too.
As far as I know Fred had his ECM re-flashed originally and then built a map using his Power Commander V with the oxygen sensor feedback system to fine tune the map. I think they use Fred's map with the flies opening sooner for the re-flash but you should check with Guhl for specifics.
-
How they gonna know?
If there was an ECM or computer issue and they (the dealer) plugged into it, it would seem they could tell its been changed ?? dunno
-
We've had very few issues, if any, with the ECU on this bike. I would have no problems in getting it done and will.

+1 for me as well. My dealer's tech is pretty cool with stuff like that. In fact, he has a 2012 C-14 and he'll prolly want the reflash too.
-
Just FYI, I called Don and he answered 2 questions for me:
1) I live at high altitude, 7500' and I wanted to make sure his re-flash didn't effect anything having to do with atmospheric pressure and inlet pressure compensation. He confirmed that this was indeed the case. So no problem with riding in the mountains after re-flash.
2) He confirmed that if you do a re-flash and then later do something like add aftermarket exhaust he will re-flash again for free just pay shipping.
That said, I'm in. I think I will pull the ECU today and ship tomorrow.
-
Did you ask about discount for group buy? Has anybody?
-
Interested in group buy....Have a ZX14r and 10 Connie.....will be at Daytona Bikeweek March 8-17, so If Guhl is going to be at Daytona, would be a good time to have him install mine while I wait....then I can report on it's performance and let all members know how it works out for me..
Someone call Guhl and see if he will do it and if he is going to be at Bikeweek next month.

Man! You had him on the phone and didn't ask about a group buy? What are we gonna do with you?

My bad. I thought someone else was on that. :-[
-
I sent an email but no reply so far....
-
I guess I'm out of any group buy because I just sent my ECU to Guhl Motors.
-
I wouldn't worry much about it....I don't think there is going to be one..
-

That's what I figured. Also snow on the ground now and more next week. No riding this weekend and probably not next weekend either. So perfect time for the bike to be down. I won't be sitting on pins and needles waiting for the ECU to come back. Instead I will be sitting on pins and needles waiting for the snow to go away. 8)

Standard price is $375 to flash your ECU. Will also flash again for changes free of charge, just pay shipping.

I'm in if the group buy is a go.
-
What gets me is it takes seconds to flash a ECU , $ 375. thank you , thank you, thank you , thank you, It's not like your gaining any great real HP increase , the big thing is opening up the secondary flys! much sooner . :o
-
That could be enough for most of us. I know I don't want to put a screwdriver to the flies and this is the next best thing...
-

It is true it seems pricy. But when you buy that $0.25 disc with software or a movie on it, for 200 times that price, you are paying for what made it possible- the labor, design, acting, performance, effects, programming, research, equipment, etc, etc. If you compare it to the labor to pay someone to professionally and perfectly remove your secondary butterflies, it is still not bad (and yet you retain the FULL functionality of the traction control). So it is all how you look at it.
-
It just gets me that we have a large # of people ready to send him $$$$$$ and he won't budge on the price at all >:(

Don't get too pissed yet, I don't think anyone has officially asked them yet...
I think there are quite a number of additional people who might do it if there was a hefty discount (25%+)
-

This is something i am very interested in.....

Put me up on this list. I'm interested in a great price.
-

I tend to doubt we'll get that much if any...but we'll see.
-
add me to the interested list. Frankly the only reason I haven't done it is that I daily commute and almost never have down time. But I have a couple trips to Peru and Ecuador potentially coming up and that's a great time to have the ECU out of the bike.
-
Its a damn shame there is no equivalent product for Motorcycles like the Diablosport Trinity. You get full control of mapping
and anything the ecu uses. The device plugs into the OBD2 port under your dashboard. You save your factory map on the unit
and flash your ecu to the specs you want... it retails for $600 and best price I have seen is 15% off.
I have it on my 2012 Dodge Charger and as long as I run 93 Octane with my mods( Cold Air intake and Corsa Extreme Cat back exhaust and BBS 85 MM Throttle body) I get major increases in power low down and I over-rode redline limiter and top speed limiter
Hemis were always peaky for TQ and HP and factory setting is 5250 redline now It is up to 6000 rpm.
I guess there are lots more cars out there than bikes so it is cost effective to unlock maps and sell the unit to car owners..

Well there is ECU Editor but it only works on Suzukis. I'm waiting on EFI Live to expand the vehicles they support but I think I'll be a long time waiting.
I don't have a C14 anymore but if I could throw my zx14 ECU into the mix than you can count me in also.

- have the scouts come back ?
:) :)

I talked to Don today and there will be no group buy, unfortunately. I think it would have happened if we could have sent 20+ ECUs in at one time (not bloody likely). The logistics of sending them in piecemeal did us in, methinks. However, with that being said, I did have a very nice conversation with him. He seems a good guy and I think we should still support him if you want your ECU reflashed. I intend to send him mine within the next few months.
-
Virginia Jim, thanks for your efforts- although I am a little disappointed with the witch doctor Guhl. I will be on the fence for a while longer..

You have to remember that he's a small businessman. The C14 is a very small market for him compared to what he does normally...(sportier crowd). The numbers for us just aren't there, unfortunately.
-
my bad :-[
No you weren't. As farkling goes with this bike, that amount of money is about mid-range or so. It's not a bad price at all as is.
-
I agree, respect the decision. I'm already a customer so don't have any skin in the game here. But I'm happy with the results/value for dollars I spent.
Rate quality, customer serivce and long term success over anything else.

What did he quote you as the current pricing to get it done?
-
$375 and that includes ground shipping back so you must pay for the shipping there as well. On the plus side it can be a quick turn around. They flash it as soon as they get it. If you need it quickly then they can ship overnight (that would cost more obviously).
-
Why don't you start another thread with those who will do it for a set price let's say $300. you need a set price, IF 20 people sign up! or if over 30 sign up! or 40?????
I'm sure ZG, he's a swinger.... and well known... ;D, would go to the OTHER forum ::) and post the same deal, hey It's winter time and that should be the BEST time for everyone including Guhl ( between snow removal)
-
Sounds like a exercise in futility. The man has set a price for his work. He's been asked about a group discount and declined.

Signing up isn't the issue here. It's getting everyone to send in their ECUs at the same time and you would have to guarantee to Don that all of the members who did sign up would indeed do that. You're more than welcome to try, though. As much as I want to do this and will, I couldn't even guarantee me to be able to do that depending on circumstances.
You would have to guarantee Don that the members would (making up something here) send in the units within a two week window (again making this up and I could work with that period) and if the numbers weren't met then the current price would go into effect.
Based on my conversation with Don, I really don't think he'd go that low but you never know. Since you are interested in this enough to make suggestions, I'm anointing you to work something out with Don (that will teach you). 717-618-4212 He might do something if we put the caveat that if the numbers aren't met within the specified time period then normal pricing applies. Also, if someone wants it quicker than normal turnaround the extra money is on the member who needs it quickly.
Start a new thread and I'll sticky it for you. My work is getting pretty intense for the next couple of weeks so you are that man... The members who sign up will have to be the ones that will do it regardless of a discount so that we can guarantee the numbers.
Mention my name that we talked about this....
-
So Jim, did you ask Don about the different reflash options that are available to us?
-
Yes, I did.
-
Yes, I did.
Oh well, that's good. Care to share that info with the class? If it's not too much trouble that is.
-
:rotflmao: You have to be careful what you say to me. You know I'm a screwball by nature...
I know he supports the Area P and K&N combo which is what I have. There are other combinations as well. He told me he has done bikes from 09 on up. 08/09 are similar. I think whomever sets this up needs to get that piece of information for each rider and verify with Don that he can do it for them. I did ask about any ABS issues with the reflash and he said that he had none as far as he knew. I don't want to lose that feature.

The Guhl Flash has been rock solid.

-

Better low end power which I assume is accomplished by opening the fly's sooner and remove the speed limiter. Also confirmed that if and when I add aftermarket exhaust he would flash again for the cost of shipping only.

Thanks guys.

He also told me that if you have an aftermarket can (not full exhaust), that'll get a different tune that a bike with a potato launcher.

Excellent! Have you had a chance to actually get ABS to kick in?
-

Nope, I'm not in on this one Cuda, I pulled the flies and did a custom map on a dyno for my PCV, I'm good. :)
-
Excellent! Have you had a chance to actually get ABS to kick in?
Yes several times due to sand on the road. The bike functions normally in every aspect other than the tweaks to the fly's and maps, which is why I went the flash route. Obviously if you ask to have the rev and speed limit raised, that will also change. But I didn't.

Guhl just called, they received my ECU this morning, flashed it and it's already on it's way back by FedEx. Weather permitting I'll be checking it out this weekend. That's customer service! :hail:

In case it hasn't been covered, just make sure you disconnect the battery before you plug it back in. I didn't (lazy) although I had no issues, I did experience on startup the dash reporting a F1 error. I turned the bike off then on and everything was ok, never to be seen again. I recall others reporting the same thing so it may just be the bike getting over a hang-over of loosing its brain for a while.
Enjoy.

:yikes: :yikes: good way to fry anything electronic :yikes: :yikes: Lord knows, I've fried my share....cut a 120v power cord with dykes (got a small mushroom cloud with that one), fried a very expensive tape backup drive, and on and on and on. You would think I would learn. Just yesterday I left the oil cap off the Prius after checking it.... Nothing to do with this of course, but I think my mind may be going, if it hasn't already.

It wouldn't be proper for me to NOT comment.
I doubt changing just the muffler requires a different map.... unless the replacement muffler is almost nothing but straight through.
-
It's all that extra weight Max, seriously changes the bike's performance metric to all of a sudden lose it. The ECU can't cope with it. Not prudent, you know.
-
: Just yesterday I left the oil cap off the Prius after checking it.... Nothing to do with this of course, but I think my mind may be going, if it hasn't already.
Last week I told one of my guys to check the oil in the new bucket truck ....... He said where is the dip stick and the oil cap ::) what a crew :o
-
The VH CS-1 is straight thru and that causes a decrease in back pressure which corresponds to loss of low end torque- believe it or not. The stock fuel map with the bazooka attached gives the engine more back pressure and torque as designed. But no way would I put that POS stock muffler back on my bike- I suffered a lot of embarrasement from my freinds and family before I threw that in a dumpster. Besides Connie seems to rev a little quicker from 5,000 up and sings a very pretty song- priceless. If only Guhl would concede $100. or so , I could have the best engine ever put in a bike. Is that asking for too much Mr. Guhl? Huh, Huh?

I posted the text from Guhl about this but in summary, he said that the program for a bike with a V&H is slightly richer than the one for a bike with a stock muffler. He also added that you can run the aftermarket can tune on a bike with a stock can.
This was in reply to "if I have a stock exhaust, should I send the ecm back to you if I switch to a V&H can?"

Besides Connie seems to rev a little quicker from 5,000 up and sings a very pretty song- priceless. If only Guhl would concede $100. or so , I could have the best engine ever put in a bike. Is that asking for too much Mr. Guhl? Huh, Huh?
:o
I sold my 2011 bazooka to a forum member for his 2009 bike for a crisp $100 bill. 8) He said mine looked better than his old one.

Got the ECU back from Guhl this morning as promised. Installed it at lunch and the bike fired up no problem and no lights or warnings of any kind. Still ice and snow on the road so will not be able to check it out until maybe Sunday. Pulled and sent it last Friday afternoon and its now back in the bike working. Great company to do business with! :hail:

The sun melted off the snow and ice from the roads nicely in the last 2 days and I had a chance to check out my new ecu reflash. The difference between the ECO map and the normal stock map used to be subtle. Noticeable but subtle. The difference between the unchanged ECO map and the Guhl "GUTS" map is pronounced. I can feel it mostly in the mid range rpm. I can also hear the difference.
Also tested KTRC and it worked perfectly. No change to the functionality of traction control at all.
If you are like me and wanted to pull the flys and add a PC-V but were concerned about the affect on KTRC this is a nice alternative IMO.

How do you go about getting this service done? I don't see anything on the
Guhl website about mailorder flashing, much less an order form to fill out and
tape to a ecm.

+1 Call Don at 717-618-4212. He will have you ship your ECU with your contact phone number to:
Guhl Motors:
4126 Oregon Pike
Rear Building
Ephrata, PA 17522
Once he receives your ECU he will call you, confirm what you want done and get your payment information. The $375 includes return shipping. My ECU was only at his shop for a couple of hours. He received it Tuesday morning, called me, flashed it and by that afternoon was on a FedEx truck for return.

Had a chance to ride the bike about 150 miles today. The GUTS re-flash ROCKS. The bike feels significantly stronger between 4500-6500 RPM then stock. It always was effortless to pass on this bike but now it's even better.

The gains with the flies out of the way at less than wot are impressive.

Is the pcm the little box under the seat secured with a rubber strap?
There are 2 modules secured with a rubber strap under the seat at the back of the bike. The one on top has 3 connectors and the one on the bottom is larger and has 2 connectors. The one on the bottom with 2 connectors is the ECU and is the box to be sent to Guhl.

If you look at this picture, the bottom is toward the front of the bike and I will reference position relative to the picture. The box on the bottom with the rubber strap is NOT the ECU. The box in the middle with the large white sticker on it is the tool box. Open the tool box and remove the tools. Remove the 4 screws holding the tools box and remove it. Now above the tool box (toward the back of the bike) are 2 stacked electrical boxes in a rubber boot. The one on top has 3 connectors and the one on the bottom has 2 connectors. With the tool box out you will be able to lift the rubber boot slightly and slide out from under the rear body work. Remove the box on the bottom with 2 connectors. That is the ECU.

I got a call from Guhl today. Couldn't speak long as I was busy at work. They will do a standard tune, which is remove speed limiter, lower the speed the flies open and some fuel tweeking. I have stock filter and stock exhaust, will keep it that way. I though about getting a can, but I like how quiet it is on long trips.
I asked if they could make it so that the bike starts off in eco mode and he said "no".
They will ground ship it fedex tomorrow, I should get it back mon or tues ( I live in NV).

Post #117 sounds like an all stock bike. I read somewhere that the U.S. spec ZX 10 bikes have the flies open later to keep noise down. That could be a reason why the C14's come neutered as they do.

I'm pretty sure my 2010 was the first pure stock bike to get flashed. There was a call put out seeking a donor STOCK bike from which Don would develop maps from. I rode to Guhl's on 11 June 2011 for the first of what ended up to be 4 separate dyno visits over the next two months. Don Guhl and his able side-kick Rob had my bike up on the dyno in no time to get baseline runs before doing the first of several reflashes. I was able to ride the bike for a period of time ranging from a couple days to a couple weeks before taking it back in with seat-of-the pants observations, followed up by before and after reflash dyno runs until we were all satisfied with the results. I believe my final map is the map that Don is currently using for stock bikes. I have more than 13,000 on the bike since the reflash and I have not had a single regret.

Here is a snippet from a Suzuki article about it:
"The official word from Suzuki is that its SDTV (Suzuki Dual Throttle Valve) system brings superb response feel, smooth power delivery, improved mileage and reduced emissions. The secondary butterflies do this by opening just enough to provide the optimum intake velocity based on throttle position and rpm rather than letting you decide with your throttle inputs. For example, if you were to open the throttle fully at low rpm on a setup without the secondary butterflies, intake velocity would drop and the engine would not pull cleanly. In addition, the secondary butterflies can smooth the off/on response by opening at a set rate again, no matter how quickly you open the throttle. And as we’re finding out with more bikes in recent years, in some cases the secondary butterflies are used to restrict the engine’s output to meet emissions requirements. On many race bikes, the secondary butterflies are removed to give the rider more control over the throttle, quicken the throttle response and remove any restrictions"
I think Kawasaki probably "overdid" the "smooth" and "emissions" part. From reading about it on other bikes, the effect of removing them or forcing them open more quickly sounds less dramatic than on the C-14.

Mine is Stock.
In addition to what Armyguns shared. I was prepared to ride 9hrs, but would have faced divorce.
After the work on the doner bike, Fred had his bike flashed, then road for a while with the PCV and Autotune with O2 sensor if I recall correctly. This information was then sent to Don for further tweaks and I think more agressive opening of the flys.
So I went with the 2nd more aggressive map.
I have no idea if Don still has the two maps for a stock bike/exchaust combo. But you should ask.
Maybe the next person who calls should ask Don to post a list.

Well in earlier posts I did talk about my desire to get an Area P slip on before getting the reflash. But since Guhl will reflash again for just the cost of shipping I decided to get the reflash now and maybe sometime down the road go for a full Area P.

Even though peak hp gain is only a couple hp, note how it is like the across the board. The thing that sounds awesome is the amount of power gained at low rpms, I think as much as 30hp more if I read it correctly. Keeping the secondaries closed down there makes as much sense as Usan Bolt breathing through his noise during the first 20' of a race.

You read it incorrectly. That was around +9 pounds of torque max down low. HP was about +7 max down low.

Well, on the Concours, 6th gear roll-on is pretty meaningless and should never be used as any metric of performance. It is a true overdrive- something most bikes lack.
Better to look at 5th gear roll-on, which is more like most other bikes' top gear.

+1 :thumbs: I never do a 6th gear roll on. In fact I seldom use 6th gear except cruising on open flat roads. But I will say this reflash has definitely improved 4th and 5th gear roll on's.

If you kept the stock headers w/cat and air filter you could pull the flys and not need a reflash or piggyback. You could run a slip on also. These bikes are mapped rich in the stock tune so unless you are actually changing volume of air flow it shouldn't affect the AFR too much. The secondary butterflys are an obstruction to air flow at less than WOT. All we're doing is removing that obstruction. If you were to go to a complete system, which drastically changes air flow, a reflash or fuel controller is necessary.
-
It's a little on the high-end, but Guhl put a lot of work into this and the ZX-14, and you have to remember that even successful motorcycle runs are limited to a few 10 thousands per year - with sport-tourers and sportbikes, they change so frequently that a huge amount of time and money can be spent to make something for them that is obsolete in just a few years and only applied to 20 or 30 thousand vehicles.
I think Don started this project with hacking the ZX14 CPU - once he had that, the Concours was either basically 'free' or more easy to figure out. Nonetheless he put a lot of time and knowhow into it.
You aren't paying for his time - you are paying for the years of experience he has that enabled him to reach this point.
Would I like it cheaper? Sure! Wouldn't we all but Don's gotta eat, buy cool toys, and he has to keep developing for other motorcycles as well.
The one thing that does make it seem expensive is you don't get the tools to do the tuning yourself - most of the time a $400 buys you the actual flashing device. I would LOVE to have the software/device to enable flashing and tuning on my own, but maybe those items are so specialized as to be cost-prohibitive for most of us.

I've heard pulling the flies causes the traction control to be 'less efficient'. Can anyone quantify how it behaves?
-

I don't have any personal experience but I remember reading early on 2010 (BC AKA: before crash) someone pulled the flies and said the KTRC is much more abrupt. Without the flies the ECU is interrupting ignition and fuel injection. So I am guessing that it commands closing the secondary's and if the wheel spin does not correct it is then interrupting the spark.
-
I've heard pulling the flies causes the traction control to be 'less efficient'. Can anyone quantify how it behaves?
I just posted this in the other thread:
The secondaries are used for traction control, starting/idle, and power control. By reflashing, it can still do all three- with it mostly changing the power control. AND the ECU will automatically compensate for the new secondaries map. AND they tweaked the fuel maps some for better performance.
If you remove the secondaries, you completely lose an important part of the traction control system (although it will still work, just not as effectively nor as smoothly). Then you also completely lose a part of the starting/idle/warmup system. And the ECU will *NOT* compensate for the loss of the flies, so I assume the mix will go too lean at points in the map. And that is dangerous for the engine. And, finally, it will not tweak the fuel map for better performance.

If you watch the videos from the other forum site ( http://forum.cog-online.org/index.php/topic,28657.0.html (http://forum.cog-online.org/index.php/topic,28657.0.html) ) , you can see that the secondaries open wide up when cold idle and close to almost nothing when the bike gets warm. I don't exactly understand the logic behind it, but I can't see them doing this without a reason.
Concours 1400 Warm up (http://www.youtube.com/watch?v=3kcF2VE1A4E#)
-
Fast idle needs more fuel/air. Secondaries are an obstruction, like a carb butterfly choke. Not conducive to EFI warmup. Mine warms up fine flyless.
-

OK. That makes sense. So they open them up wide during the fast idle, then snap them shut at low idle, ready for driving away (I guess). I assume if you try to drive off while fast idle they will still shut as programmed? (That is the odd part).

Results are immediate per the Fly's and updated maps on start up. My basic understanding, our bikes do not have an O2 sensor, so there is no updating of the maps, their static. I think I heard the European bikes do, but I'm not sure To acheive the same result you need a PCV+Autotune, i've read a few articles where racers will flash their bike + install the PCV+Autotune for optimal results.

Fedex dropped it off 40 minutes ago, i installed and went for a ride.
Impressions-there is life below 4k rpms! Wack the throttle open at 3500rpms and the bike will give a little snap, really move. Tractability is also excellent, you can ride slowly smoothly.
The difference is really pronounced when you flick back and forth from the eco mode. Honestly, I never thought the difference in power was that much different from regular mode and eco mode so I just kept it in eco.
Now, it is pronounced.Twist the throttle at 3500rpm, bike moves. Twist the the throttle at 3500rpms with eco mode and slowly winds up lethargically.
On the freeway, passing is great, rather than down shift, just keep it in 6th and let the torque do the rest.
I'll stick to using eco mode a lot, when traveling, but at least i have reason to switch to regular mode when i have some nice roads to carve up.

See, you are like me- eco and regular felt similar so you went with the one that gave the promise of better mpg. Now, I too will probably only use eco for highway driving.
My '91 Katana 1100 used to be my go to bike for city driving simply because it had better low/mid range. Now, the C14 feels like that katana 1100.

USA C-14's have no O2 sensors. I am not sure what system is used for the C-14 when it has O2 sensors, but it is most likely going to rely less on maps and more on the data from the sensors (that is the whole point) so I don't think the flash is going to be compatible.
There might be a DIFFERENT flash that would work on the O2 models, adjusting the underlying tables and also the maps for the secondary butterflies are likely the same. If such as flash exists, I don't know, but have not heard of anything like it. There would probably be zero chance Guhl would ever develop such a product, though.

I can confirm we don't have the 02 sensor, I think Asia and European bikes are the only ones which do. Most likely for emission standards and kinda sucks if you ask me.
As for the flash being invalid, I couldn't really say not my area of expertise. But here's what I think and that's just an opinion.
1) The big improvement from the flash is the Secondary Flies opening sooner. I assume this would be the same on both types of bikes. The tweaks to the maps are minor, and if you have the O2 sensor then in theory the bike should take care of that itself. I think.
2) Someone would have to call Don and ask if he saw O2 code in the ECU. Assuming he didn't look, then someone should look up the ECU Part and see if its different on the US bikes vs Asia/Europe. If its a different codebase/flash then it should be a different part to denote it.
3) Assuming its the same....then the big question is.....could Don hack it and enable us to add our own O2 sensor like you do with the Autotune. That would very cool!!!!! But I'm sure that's a pipe dream.
Or someone could ask Fred Harmon on the COG Forum, who's the expert on all this stuff and he probably could call b^!!sh!$ any of this.

The microfiche on Bike Bandit shows 3 different ECM's 21175 A-C
When Don flashed mine I had the option to change:
RPM limit
MPH limit
Fly's open sooner
richer map for aftermarket pipe
On a Europe model the first 3 options would still apply, but with O2 sensors the mixture takes care of itself.
And YES it would be cool if Don offered the option of adding O2 sensors to our bikes.

As stated already, no O2 sensoes on USA bikes.
GUHL has a flash for the C14's with O2 sensors as well. Contact them for more information.

From what I recall and it may be with the PC V, you can get an o2 sensor to aid in the adjustments. Don has worked with this combination and of course it may have been with FredH. It could also have been with a dual exhaust?

OK, that surprises me greatly. Are you sure that is for a non-US bike? Or is that for a US bike with an aftermarket O2 sensor added being controlled by something else?

US bike with aftermarket O2 sensor, PC V.....I think but you would need to talk to Don at Guhl to be sure.

There was someone very early on (may also have been on the other forum) that was on your side of the pond that sent their ECU in.
Now this was a while back and I "may" be not remembering correctly. Either way, contact Guhl. He can set the record straight,

Nice! Thanks for posting Conniesaki!

One thing worth mentioning is the flies still being closed at around 2200rpms. I remember reading about this on another thread and some were wondering why not just keep them totally open.
I can say that the amount of time it takes the bike to go from idle to 2500rpms (or whatever it may be) is less than a blink of an eye. I think at real low rpms (from 1000 -2200rpms) you are really looking at diminishing rewards here as the air flow is pretty low.
I can only think that leaving them closed a little bit was to make for better off idle response (maybe make less "twitchy").
It is 65 degrees outside and sunny- I will ride today and, being in an extravagant mood, will only ride in Guhl mode, not even using eco mode for the 20 minutes that I am on the freeway!

Way to take one for the team.

Well, here's my bit for the team. I used Guhl mode for first half of my ride, then eco for the return. I know there might be some variables to affect numbers and need more time (rode total of 90 miles) but here are my mpg numbers (half of the mileage was on the freeway)
Guhl: 44.7 mpg
Eco : 46.1
I was surprised to see the difference between the two so low, must be some truth to Guhl taking a lot of richness out of the mix.
