So, it seems my '08 has developed a surging from 2500-3500. I have the full areap, PCV and Autotune. At first I thought it was a tank of bad gas (same station since bike was new). The evening before it started the bike ran awesome, the change only happened after a fill up. I ran half a can of seafoam through the tank, filled with fresh gas from another station (use premium). The surge only happens at small throttle openings. It has become that on/off feel. If I pin the throttle everything feels normal, but when it's surging I get the feeling I am only on 3 cyclinders or starving for fuel. This evening I will be pulling the airfilter and draining the tank to see if it may still be the fuel or the filter, which has about 10,000 miles since I last cleaned it. I will be sending a copy of this to Jamie to see if he has any suggestions, maybe something with the PCV or auto tune, I'm just not sure, but I need to figure it out soon, I have an Advanced Street Skills this Friday and I dont want a sub par bike on the track. Any and all suggestions will be read carefully and I promise I wont reply LOUDLY!
Thanks in advance,
Chet

Well, here is a pretty broad but free idea Chet....
My bike tends to get sluggish at small throttle openings over time. The trip I took out your way seems to have been especially hard on it. Fuel injector cleaner straightens it out but the bike seems sensitive to the brand and type used. This last time I tried Chevron Techron (one bottle in one tank of fuel) and it had no noticeable effect. Then I tried Gumout, the specific type that is supposed to clean injectors, intake valves and combustion chambers (a very specific solvent is used in these types). Again, no noticeable effect. I currently have a tankful of the one that has worked well in the past- STP fuel injector cleaner, the stuff in the black bottle (different formulations are in different color bottles). About 80 miles into the first tankful using STP and the throttle response is getting crisper, the throttle is more sensitive and the bike runs stronger at lower RPM (all indications of dirty injectors that will not atomize fuel). The other thing that happens is that the crankcase oil turns almost black and becomes extremely thin after using this stuff. I take that as a good sign that the solvent is making it by the rings and into the crankcase. None of the other cleaners had that effect on the engine.
My suggestion would be to give it a try- use about 1/2 of the bottle in a full tank of fuel and see if the bike runs better / crisper. You absolutely will want to change the oil after that one tankful though because the oil will be like water.... black, stinky water.

STP, black bottle it is! Just changed oil last week :( Oh well. Do you think I may have a partially clogged fuel pump screen? I go through about 2 tanks a week so I kinda ruled that out.
-
If you use expensive motor oil you might want to consider draining it out and saving it. Then use something cheap, like Rotella 15W-40 for the injector cleaning tank. It is a terrible waste of oil as it really does thin it down to a scary level. Rotella is only around $15 but expensive oil changed out in a week is a shame....
You probably do not have a clogged pump screen but the injector cleaner will help clean that up too as well as the pump itself and all the fuel passages. Unfortunately the STP brand is a bit aggressive (which is why it works well as a cleaner) so I would not use it too often as it <may> be hard on some fuel system components. I used to use it every second oil change (3K miles between oil changes) but have not used it in a while- maybe 15K or 20K miles so I am sure it is time.
I usually do not think too much of 'potions' and magic fixes but injector cleaner really does seem to work on both cars and motorcycles. I saw a chart about the effectiveness of various F.I. cleaners and some were rated pretty highly while others were shown as ineffective. Unfortunately I did not grab that chart when I had the chance.

Do you happen to have a link to that chart, if it was online?

So, just returned from the on base PX, they didnt have the black bottle, but they did have the concentrated in a silver bottle/gold label. I also bought a bottle of Gumout Regane complete. I'll dumb em both in, 'less of course ya say not a good idea, after I clean the airfilter, I'll let the bike idle for 5-10 minutes, shut her off to cool down, then take it for a 30 minute ride. I'll report what success, if any, I have.

Personally, I wouldn't use them both at the same time Chet. The chemistry may not be compatible, you never know what may happen.

You don't want to use too much of the stuff- if the label says it treats up to 21 gallons (this indicates relative strength), I would not use more than about 1/2 of a bottle in a full tank of fuel. It is best to add the stuff when you fuel up so it is thoroughly mixed with the fuel in the tank; I usually put a gallon or so of fuel in the tank, then 1/2 bottle of F.I. cleaner, and then fill the tank the rest of the way. As I said, the stuff is a solvent and <can> be hard on some soft parts of the fuel system (think of plastic in acetone, not good). As Conrad said, I would not use two types at one time but not because they will not mix, just because they are both solvents and it would be too concentrated in my opinion.
Once the F.I. cleaner is mixed in with the fuel, I try to use that tank to as low a level as I dare and then fill it again so that the next tank does not contain much of the F.I. cleaner. If you fill up when the tank containing the F.I. cleaner is only ½ gone for example, the next tank will also contain a lot of F.I. cleaner. Run that first tank down quite low, refill the tank and change the oil.

Wow Conrad, you seem to be confusing fuel injector cleaner with the Demon Core.... http://en.wikipedia.org/wiki/Demon_core (http://en.wikipedia.org/wiki/Demon_core)
:o
But I do agree that two containers probably should not be used together- not because they might react (they might I guess?) but because it would put a lot of F.I. cleaner in the tank at one time. I believe too much of the stuff <might> attack plastic and / or rubber fuel system parts. Sort of the way acetone can be mixed with gasoline to increase the gas's octane rating..... until you use a bit too much in a Corvette only to find out that those fuel tanks contain a rubber bladder, and the semi- liquefied bladder will NOT pump through the entire fuel system. ??? >:( :-[

OK, no cocktails! I will be doing the smell test, whichever stinks the worst gets dumped into the tank ??? The gumout wins, it is nasty smelling!!! The STP smells almost like diesel.

I may have exaggerated the situation slightly. I just didn't think that it was prudent for Chet to use all that solvent in poor Connie at once.
-
Could it be an issue with the O2 sensor used with the Autotune setup? I don't know if those wideband sensors are known to fail or need regular replacement.

That is a question I have, it has been on the bike for some 30000 miles and I have pushed the extreme a time or two and also have a wonderfully boring commute on the I5 rolling parking lot :( I will do a little playing around if the cleaner and air filter dont solve the problem. I'm waiting on word from Jaime, he may have some insight.

Bah! A C-14 can take almost anything thrown at it, including unlimited solvents in the fuel tank!
Not really but I am enjoying the distinct lack of Mary Jane Tinklepants, hand- wringing, "should I be worried" postings here lately. Not sure what happened but it seems to be a different demographic and I like it. We seem to have a can- do, forge ahead group gelling around the virtual camp fire. So buck up folks and point your noses into the wind and ride.... we need tough people to ride C-14's and post here; dem girly- men can post somewhere else ('my tire was 0.002 PSI low today, should I be worried?' and so forth).
<smiley, kind of>

What about E10 vs. non-Ethanol? Changed between them lately?
I'm still experimenting, but while doing the Ride the Ribbon event a couple weekends ago, I was filling with non-Ethanol 92, mainly for the 5mpg increase. When I returned to the metro area, I ran for 2 more days on that fuel. When I finally refueled with Chevron 92 E10, I noticed the throttle control became much more abrupt. No surging like you report, but certainly much more of the 'light switch' control it has been in the past. To be honest, I didn't even notice it smoothed out (probably too tired), until it was back.
I found a station outside of town that carries non-E10 92, so I'll be heading that way for the next fill up, to continue the experiment.
Probably has nothing to do with your problem, but something else to check.

:rotflmao: :goodpost: Get out and ride, indeed. Put the miles on and have fun, that's what riding is about for me.

Might be a good time to stick in a new lambda/O2 sensor (after you use the fi cleaner). The Bosch sensor can be had for around $ 30. me thinks.
Fretka

Thanks Fretka, it may be something I pick up this evening. A quick question, my AFR reading on the Dynojet PCV program shows a steady 9.99 AFR, regardless of throttle position or RPM. Even tried the differant maps, do you think this may be an indication the sensor is bad? Accepted trims, no change to readout.
I cleaned out the filter, wasnt too bad. I added the FI cleaner, ran it for 10 minutes, shut her down, repeated several times over the course of 2 hours. Still getting the surge. I also tried a coupla differant maps I had stored. Havent ridden it yet, but the surging is still there. Maybe my engine is getting READY TO GRENADE? ;) (MaryJoe Tinklepants for BDF!)

So, I answered my own question, if the AFR reading is showing 9.99 there is either a faulty sensor or faulty connection. I did a quick check last night, all looked OK, i will look closer tonight as I prepare to pull the sensor. Fretka, you wouldnt happen to know which sensor I need, do you? Is the Lamda Wideband generic or will I need a specific sensor?
Thanks,
-
You are going to need the correct sensor. That looks like a Bosch LSU4.2 5-wire, which is a wide- band, heated sensor and very common. About $75 / $80 from a discount vendor. But make sure that is the sensor they are using before buying one because they are generally NOT returnable.
Nice job Fretka on mentioning that, and nice job on checking it Chet. This is how an interactive forum should work! Now all you are going to have to do after replacing the O2 sensor is to put the dirt back onto the air filter and get the F.I. cleaner out of the fuel tank. ;)

Who sold you the sensor? Did it come with the exhaust system? If so, I would go through them to get the correct one.

Can you just turn off the autotune and run a generic map on the PCV to by-pass the o2 sensor and see if that cures your surging?

I could, if I had a generic MAP!

Came with the kit I got from Jaime at Fuel moto.
Brian, will there be a part number on the sensor? Friday is looming and I'd hate to use the KLR at the track :yikes:

I was say yes, I am waiting on a phone call from him, he was on another line helping some other lost sole! The auto tune is a kit from dyno jet, I'm still looking for a number so I can find one local. What I may end up doing is as suggested, disabling the auto tune and running a map from fuel moto, which I'm sure Jaime will send ASAP.
-
That looks like a Bosch LSU4.2 5-wire--we have a winner!!!!
I just need to find one local, like soon.
-
Yes, there is a number printed down the side of the sensor, at least there is on a 5-wire Bosch sensor. Grab the number from your sensor (you might have to rotate it to see the number) and punch it into Google and that should tell you exactly which sensor you have.
As someone already said, the fastest thing to do might be to just grab a map and turn off the tuning function of the PC V.
Best of luck and let me know if I can help in any way.

That sensor is used in a lot of German cars such as Volkswagen, Audi and Mercedes Benz. I believe it will be available in local parts stores. It is worth about $70 best price online so you can use that as a price point in case the local store wants $229 for them.
I will try to look up a valid car that comes with that specific sensor.

There are a lot of them so you will need to use the exact part number on the side of the sensor you have. Just type it into google and it should kick back enough info. to find one through a local parts store.
I checked on a couple of sensors for VW and Audi (random engine choices on my part) and they do not stock them at Auto Zone. They have a 2- day delivery deal though, not sure if that is fast enough for you.
You also may be able to find a sensor for an Innovative Motorsports setup or a MegaSquirt F.I. controller locally too- they use the same sensor.

Just got off the phone with NAPA-they be stumped, but they said they do have a large selection on hand, I'll pull the sensor and take it to them so they can referance the part number. Thanks much to all,

Using that web page and following around the 'net a bit, it seems that the correct part number is: Bosch 16065 or Bosch 16066, which appear to be identical other than the price. I have no idea why they are identical but different prices, perhaps the more expensive ones are fresher and the other ones have past their expiration date. At any rate, either of those two part numbers, or their equivalents, should fit the DynoJet system.

16065/16066 plug ends are wrong. I wonder if Dynojet specs the cable on their sensors?
-
I just went to the page you listed, pulled up the O2 sensor number (48292000), then plugged that into Google and found this reference page: http://www.oxygensensor.net/widebandsensors.php (http://www.oxygensensor.net/widebandsensors.php)
That page does have another type also listed for Dynojet usage a little further down the page: Dynojet part number: Dynojet Wideband Commander # 48292001 , which apparently crosses with the Bosch number: 17018, and Bosch number: 17025. These appear to have different cable lengths and do have different prices. Is that the right connector on the end?
Unfortunately I do not have a Dynojet O2 sensor so I cannot compare. I do have an Innovate O2 sensor but clearly that is not the same connector as <any> of the Dynojet systems use.
Chet, how are you doing with this problem, any better than I am? :(

How do we get that in the appropiate sticky?

So, heres the update, NAPA didnt have the 02 sensor, I took the one off the bike and the part number is 17205. Hold onto something, with discount it is 124.07-before taxes. Jaime sent me an email with his map for the flieless full system, he also recomended that I check all connections as his experience has been they work loose. Everything was tight and clean. I put in the old sensor after I cleaned it as best I could and started her up. I was getting an intermitant reading from the AFR readout, but it stayed mostly (technical term) on 9.99. I uploaded the map from Fuel moto, disabled the Auto tune, rubbed my fob, and BAM!!!! Instant success. I am giving full credit the awesome powers of KiPASS, and of course my bestest friend, MaryJoe Tinkerpants ;)
I will install the new sensor tomorow eve and will send a followup as I get it. Well, back to the bike, she's 'bout half nekid and ready to be ridden 8)
-

I'll think about it and we'll have something tomorrow linking this thread.

First of all, great to hear you found a solution (the fixed map). It is not quite clear where you got the new sensor but it sounds like maybe it is coming into NAPA in a day or two? If you did order it you probably cannot send it back- that price is not all that bad, and it sounds like they did help you out so.... whatcha' gonna' do.
Not to rub salt into the wound but this place: http://www.oxygensensor.net/widebandsensors.php (http://www.oxygensensor.net/widebandsensors.php) has that sensor for $70, and believe it or not, they ship them from Washington state by the looks. This info. is really for anyone else who might need a sensor in the future. I have no knowledge or connection with this company whatsoever, I just found them on the 'Net so I cannot vouch for either the company or the product.

Yep, NAPA will have it tomorow morning, I'm feeling a cold coming on-hack hack, I found em cheaper but I needed it by tomorow, so I paid the piper. The test ride went great, no more surging and the rev limiter seems to be closer to 2nd :D I'll ride her in tomorow, pick up the new sensor, install, set AFRs, go for another test ride, then change the oil. I'll have around 1500 on it so it wont be a large loss. I'm thinking I'll try some sea foam in the mixture, drain and fill er with some fresh 20W40 Lucas full syn. I may as well do the rear as well.
I got a phone call from Mary Jane Tinklepants, seems she has been looking for MaryJoe Tinkerparts for some time. MaryJoe used to own a C14, seems she experienced some kinda fob fobia and turned on the KiPASS gods. She traded it in on some old outdated bike and now rides an FJR all wrapped up in a fuzzy snuggy.
Jaime at Fuelmoto was prompt and offered great advice, he sent me the base map for my bike, and cautioned me to verify the connections. A subpar retailer woulda been pushing another sensor, not him. He will be keeping my buisness and I hope others will as well.
Bottom line, she's running and well, I am looking forward to having the auto tune back up and running.
Thanks to all,

Additional information requested.....when are O2 sensors used? Where there is an aftermarket dual exhaust such as the Full AreaP?
-
1) When a Dynojet Autotune is installed with a Power Commander V.
2) '08 Concours 14-- Zx14 headers, mid pipes, Muzzy CF duals.
See following post from SOP for benifits.

Additional information requested.....when are O2 sensors used? Where there is an aftermarket dual exhaust such as the Full AreaP?
The full AreaP is a 4 into one exhaust with the option of having an 02 bung welded in so that the Auto tune module can be added to the PCV. Gives you the ability to fine tune the air fuel ratio (AFR) to better suit the riders desires, such as more power or better fuel economy. In effect becomes a rolling dyno in the sense it tunes on the fly. The drawback? As is evident, it adds another link into the chain of devices, and as we all know, links can break :( I went the route for 2 reasons, adjustability, and to ease my almost guilty mind over losing the cats.

Jim, thanks for labeling the thread better.
Ride in this Morning was most excellent, nice smooth throttle response. I'm back in control of the throttle. I'm going to take my laptop with me tomorow to the track, gonna play with settings a bit. I want to see if an average rider will really feel the benefits of an 02 sensor.
-
You know, O2 sensors last a pretty long while in cars. You haven't had yours in there that long. I wonder if something caused it to go bad? These sensors are usually pretty robust. They can be contaminated by overly rich fuel mixtures, though.
-
The sensor was nasty, I'm certain that if the sensor wasn't faulty Jaime will take care of me with another auto tune module. I will be sure to post up results. I had somewhere in the neighborhood of 30-40k on the sensor, either 4 or 5 trips to the track, and lots of rolling parking lot commutes. None of which would be overly kind. All I know at this time is once I disabled the auto tune function she runs great.
-
Quick update, replaced the sensor, the AFR readout is now showing adjustments. I'll give more feedback as I have it.
Thanks mama Kaw for KiPASS, without it I'm certain my bike woulda died a horrible death ;D
-
I know I'm late to this party, but if you had found an O2 sensor of the same brand with the same number and color of wires but the wrong connector, you could have just changed the connector. I've (in the distant past) bought the Bosh generic O2 which comes without a connectoe and then cut the original connector off of the bad O2 and spliced it to the new O2.

I know I'm late to this party, but if you had found an O2 sensor of the same brand with the same number and color of wires but the wrong connector, you could have just changed the connector. I've (in the distant past) bought the Bosh generic O2 which comes without a connectoe and then cut the original connector off of the bad O2 and spliced it to the new O2. Worked for me and the new O2 was a lot less $$$. 8)
Thanks Pope, I did have that thought, but time was a factor, I'm almost out the door for the track ;D Should be an awesome day, temps will be in the low to mid 60's and rain wont get here till tomorow or Sunday so I should have gobs of power and a dry track.

Sensors can be affected by rough handling, moisture condensing on the probe due to physical location and certainly many fuel additives that one might use for various reasons.
Glad to hear all is well.

So, I ended up doing two levels on the Street Skills, meant more track time, but no time to do the switch between auto tune and Jamies MAP. Bottom line is verything worked awesome, topped out at about 145ish several times (indicated, GPS lag time sucks) on a 3/8ths mile section before a coned off chicane. No hickups, gobs of power and a massive thirst for fuel, readout showed 24.6 for the entire track session.
A side note, the EBC rotors and EBC HH pads never showed a sign of fade, vastly superior to the CL pads in regards to track type use. Once I set up an account with you tube I'll post up some vids I shot with my Contour HD.
Fretka, up till my trouble shooting efforts I didn't use any additives, I usually burn through 2 tanks a week so fuel stays fresh. It has been known to be on the wet side here in WA State. I'm not sure if our premium fuel has ethanol or not, but it wouldnt surprise me if it did. I'll be keeping Jaimes MAP saved so if I ever have the surging issue again I can simply turn off the auto tune, his MAP really works good. Up next, I need some time to install the ZX14 TBs, need more power ;D

I am thinking about buying the autotune along with a full AreaP (already ordered the exhaust). Is this worth the $200 to possibly get a little better economy and performance. If I can get by without an extra link in the chain of modifications, I probably will. But if anyone has real world experience of getting an extra five mpg or more, then it might be worth it to me. If it is only worth a mpg or two then I will probably pass. But I am having the bung welded on with and Jaime said he could include a cap so that if I change my mind down the road I will have the option of adding it without modifying my exhaust.

Jeremy, I installed a PCV w/autotune when I put the zx dual system on. Stock I was getting an indicated 32-36 mpg. After the install 38-44 indicated. I would recommend the complete system.
As always JMHO.

Jeremy, my experience is the consistency of 42 MPG year round. Although I had an issue with the 02 sensor, I'd do it again. I havent heard of anyone else having this issue so it isnt a widespread problem that I am aware of. Remember, I'm out here in the Pacific Northwet and I ride in the rain, not to mention I am on a track twice a year were I really get to open her up over and over. It's also nice to know I have control of my MAP. FRETKA has been a big help in learning what to do.
So, yes, to me it is worth the extra money :)

I guess I am just "afraid" of tinkering with my maps (this is why I haven't even downloaded my PCV software onto my computer). I have had great luck with my PCV since it came preloaded with Jaime's map, and don't want to jack it up. I will change tires and check valve clearance in a heartbeat but when there are a bunch of electronics involved it gets intimidating. I guess I just need to do it and if there are problems, I know who to call.

Roger that!
