Title: Testing the Rostra cruise control
Post by: skeet on January 03, 2015, 08:23:05 AM
I got everything install and wired. Even got into diagnostic mode to verify all the signals going to the controller.
Now is there a way to test the operation without going for a ride?
Too mich snow and ice here in northern MN. I tried running it on the center stand at about 25 mph but that is too scary and the cruise did not work.
Thanks,
Wayne

No, not really. As you found out, the centerstand method will not work correctly and the Rostra will jerk the throttle so hard (Easy Boys!) that I really hesitate to recommend that as a method of testing. If the Rostra did take over and move the throttle at all, you can be assured that the unit is installed properly and is working but without the load of actually riding the bike, the realistic behavior of the Rostra (or any cruise control for that matter IME) cannot be tested.

To the best of my knowledge, and I have assisted with dozens of these installs, if the unit passes all parts of the diagnostic, it will work with the single possible exception of having far too much free play in the cable. So you should be ready to ride along America's highways and feel free to fall asleep while being confident that the bike will maintain speed....  :o ;D

LOL!!!

Seriously though, I have a medical condition (some type of sleep disorder) and actually CAN easily fall asleep while driving, even on the Concours without cruise control :(   Have to be very careful, especially at evening or night (and such driving is the ONLY time I consume caffeine, which works and is less scary/complex than the amphetamines the doctor wanted to prescribe).

Yeah, I had a friend fall asleep on his scoot a few years ago (BMW RT) on the highway in TN. He woke up to find the Earth and sky exchanging positions rapidly and when that stopped he could not get up due to the broken ankle (his only injury but the bike was wiped out). And he was not using cruise control- he never does because he does not like the variance in speed (???).

A lot of long distance riders have the constant worry about falling asleep while riding. I like to make the amused observance that it is the SECOND night that is the difficult one (on a 50+ hour contiguous ride). :-)  Even dem dare IBR riders sleep some on the very first day....  ;D

Skeet,
After installing mine, I weighed the odds between testing on the centerstand and manning up and playing crash test dummy...

So I tested mine on the centerstand, holding it back to make sure it couldn't vibrate off the stand and take off.

Mine engaged, but had to be in 5th gear and at least 35 mph.

However, without the friction and load of the road against the rear wheel, it will rev up and down, repeatedly. But, as Brian stated, it proves it's engaging.

When it does this on the centerstand, it's merely exceeding the set speed, then slowing, then trying to reacquire. Once it passed this test, I went for a ride and it worked perfectly.
That was over 2 years ago, still works perfectly.

That's how I did mine.
YMMV, though! Be safe.  The key is it has to be engaged at 35 mph or faster, and in the higher gear. Hope this helps.

I think that sounds more dangerous than testing on the road. (especially if you repeatedly practice hitting the kill switch before starting out on the road)
Regardless, I'll bet you got some K-Trac error msgs on the screen when you did that, right Bob?
Title: Re: Testing the Rostra cruise control
Post by: C14lvr on January 03, 2015, 07:25:19 PM
Yes, it will give you a K-Trac error. That will reset when you turn off the ignition, then restart...on the ground.

But, to me, this wasn't even close to being dangerous.
To others, it might be. And it would be a disaster if it ever came off the stand.  :o

But I knew I could hold the bike back and keep it steady on the stand while gradually increasing speed.

I did NOT know if I would be able to turn it off if it went WOT, besides the kill switches.

What startled me was the initial engagement, and sudden accel/then decel/ then accel!

Now when I install one, if it passes diagnostics, and if the switch lights up, I ride it.

This weekend, I'm currently installing an Audiovox 100 system on a 1999 Honda Valkrye.
Title: Re: Testing the Rostra cruise control
Post by: B.D.F. on January 03, 2015, 07:43:06 PM
Yeah, when the Rostra grabs the throttle during the center- stand test, it can be quite a rude surprise. That is why I do not recommend doing that in the tutorial or usually recommend doing it at all. That said, there is a way to test it that is relatively (?) safely: run the bike up to about 40 MPH in 6th and hold the speed steady with the throttle. Engage the CC (this is where an 'engaged' light really helps) and then slowly..... slowly and gently allow the speed to drop about 3 or 4 MPH, no more than 5 MPH no matter what. The CC should start to open the throttle to try and correct the speed drop but it may be violent so as soon as you feel the CC engage, either turn it off or disengage it. Never, EVER let the CC actually control the throttle for more than the smallest amount of time possible because that violent open / close cycle will rock the bike pretty roughly and should the rear tire touch the ground, someone may have to paint the back wall of the garage :-( 

Warning: technical content follows: the reason this happens is because the CC  is calibrated to open the throttle in minimum increments, which are actually fine when the bike is on the road but far too large when there is no load on the bike. The system then overcompensates for the first overspeed cycle by closing too far (usually all the way to idle), the vehicle speed drops rapidly and the CC then opens the throttle again but much further and faster to compensate for the rapid vehicle speed drop. It is all an unstable oscillation due to a system calibrated for a much larger load (the engine and rear wheel can accelerate MUCH faster than they can having to accelerate the whole motorcycle) than just moving the drivetrain.

Neither annoying/improper/illegal mufflers nor annoyingly/improperly used high-beams make any difference when I get in that mode.  It is really scary.

Anyway, back to the Rostra cruise....

Well then I guess I wait until spring to find out if everything works.
Fell asleep on my Honda V45 on the way home from the night shift once felt the bike going over and woke up in time to keep it upright. Needed a change of shorts after that.
Title: Rostra help please
Post by: sailor_chic on February 03, 2015, 07:22:45 PM
Hey guys, I have almost completed the install of my Rostra CC, with the exception of passing the diagnostic test. The kicker here is that I cant get past step one. To the best of my knowledge, I have it wired exactly how it should be and my connections are right on. The only difference that I am coming up with is how the brake relay is wired, and I am thinking that this could be part of the issue. Brian and Fred say one way, and Rostra says another way. Regardless, neither way works. The problem that I currently have is the led light inside the actuator is ON once I put it into diagnostic mode, and it should be off.
I have even tried waving the almighty KiPass over the bike, hoping that its magical powers would heal everything, but it didnt help. So I have found one flaw in the KiPass.
Title: Re: Rostra help please
Post by: B.D.F. on February 04, 2015, 05:16:49 AM
The brake light relay must 'click' with the brake light activation. That is step one no matter what else. The method shown in the tutorial works- honest.

We will get to the bottom of this and soon, you will be able to sleep while riding down the highway in comfort.... :-)

By the way, I am really suspect that KiPass failed: did you say the incantation correctly and light the two sulfur candles? You cannot expect it to work without the proper accoutrements after all.

sailor_chic, I see from the other thread that you got your Rostra working. Congrats, you are going to love it I'm sure. However, enquiring minds want to know...

Did the candles and waving fob work...or did you just give up on diagnostic mode and go out and test it....or did you find the problem that was preventing the diagnostic mode from working the way you expected it....or did I not see the post explaining all of this....or what?

I had a  phone call or two with Brian, and he walked me through my connections and tested some things, and he said I was good to go, regardless of what the test lights on unit showed. So I took the bike for a little ride with half of the fairing removed and the unit engaged as it should. Today will be a 300+ mile test.
Many thanks to Brian for his time and expertice

Yeah, they can be finicky to get into diagnostic mode and I have no idea why. Electronics in general are not 'finicky' either so not sure what is going on there. The Rostra is a fine, robust unit that serves very well but I do not think it was designed by Steve Wozniak, if you know what I mean....  ;)

There seems to be several incidents of having trouble getting into Diagnostic mode with Rostras that then seem to work fine afterwards during the road test.

Yeah, the Rostras have proven pesky to get into diagnostic mode. Part of the problem is that getting into diagnostic mode depends on which switch is being used and the rest of the problem is that they are just finicky.

Nicole went through a solid, manual testing though, circuit- by- circuit and I was pretty sure it would work.

Yeah well, I have seen a lot of professional installations that do not reach anywhere near that level either. I think that is the cleanest, nicest installation I have seen so far, and I have seen more than a few Rostras installed....

Nicole is to Rostra as Walter White is to crystal meth. Mark my words, that is going to show up on fifth grade I.Q. tests before too long....  ;D

Wow gentlemen. I am very appreciative of the kind words spoken about my installation skills ;D. When doing a project, such as a Rostra, I really do try to make thing look as professional as I possibly can.

As Brian spoke about my diagnostic testing, I wasnt able to get the unit itself to go into diagnostic mode. Yes I did have the NSS wire disconnected. Brain  walked me through the connections that I made and the necessary voltage required for it. The only adjustment that he did have me make was one of the dip switches.
I made the bike "rideable" and physically tested the Rostra and it worked perfectly!

And since I do live under a rock, I had to Google Walter White, so I could be as smart as a fifth grader.

On a flat road, it will not vary 1 MPH at highway speeds (65 MPH and up). Hills, both going up and going down (Don't make me say it!), the vehicle speed may vary by 2 or 3 MPH, usually a little less at highway speeds. The Rostra really does work best at high loads: either highway speeds, or at very low engine speeds when going slower. For example, the Rostra will work reasonably well at 30 MPH but the engine has to be in 5th or even better, 6th gear. Yes that does result in rather low engine speeds but that is what is required to tame the Rostra. At that same 30 MPH in 2nd or 3rd gear, the CC will oscillate, sometimes kind of annoyingly so.

Brian

question, but wasnt sure where to ask it

anyways, how tight to the set speed does the rostra hold, say with semi flat roads, no huge hills or anything, just normal midwest roads.
thanks much
(find myself using the cruise in the car every day, to maintain my above the limit speed to an acceptable level)

For example, the Rostra will work reasonably well at 30 MPH but the engine has to be in 5th or even better, 6th gear. Yes that does result in rather low engine speeds but that is what is required to tame the Rostra. At that same 30 MPH in 2nd or 3rd gear, the CC will oscillate, sometimes kind of annoyingly so.

30MPH in 6th????  I would never do that.... even 5th is lugging!

I am not joking... I would typically use 4th tops at 30MPH cruising.  Sounds strained at 5th, I can't imagine 6th!  I would be disappointed if I had to lug the engine just to use cruise at 30MPH.... fortunately, there aren't a lot of places I would want to use cruise on a bike at 30 (I don't HAVE cruise on the bike... although I do on the car and use it a LOT at 30-35MPH around town, to avoid tickets and such).

However, I want it clear that it was not I that started this off topic discussion (not that I haven't done that several time before  :-[  ;D ) from Rostra testing to lugging. Lugging an engine is not something so simple that one can tell simply from gearing and speed that it is happening. I'm sure there are many here that will disagree and say so with lots of exclamation points and talk about all their track experience. Some will go on to say that they never shift up out of 4th unless they are going at least 70 mph (60mph? 82mph? whatever, pick a number). and the rest of us that don't follow their guidelines are doomed to knocking big end rod bearings etc etc.
Lugging has at least two additional factors besides gearing and speed. Throttle opening and resistance to forward motion. On level ground with calm to low headwinds, properly maintained bike including properly inflated tires, GVWR compliance, and perhaps some other factors that I can't think of right now, a C14 in 5th gear with only enough throttle opening to maintain 30 mph is not lugging the engine. Kawasaki agrees with me.

Quote from: C14 Owner's Manual
(http://fartymarty.smugmug.com/photos/i-GpFKHVw/0/O/i-GpFKHVw.jpg)

Now returning to topic, if testing a Rostra in 5th at 30mph and it starts opening and closing the throttle in large movements in it's attempt to maintain speed, then there is most likely some lugging going on during the wider throttle openings. If that happens discontinue the test and check to make sure that there isn't too much actuator cable slack at closed throttle, or simply test at a higher speed. I agree with Brian (at least I think that is his position on it), I would not test a new Rostra install in any gear below 5th until I was sure it was performing properly in the higher gears. Such a test would, I think, be for grins and giggles as I don't know why anyone would care how it performs in the lower gears, unless of course they never shift up out of 4th below 70 for fear of lugging the engine (::)) while riding in a 60mph speed zone.

Post by: B.D.F. on February 22, 2015, 10:11:16 AM
The Rostra is not optimized for motorcycle use, especially the more powerful motorcycles. Keeping the engine speed low by using higher number gears is the only way to 'tame' the Rostra at low loads; at higher loads such as on the highway when wind resistance provides all the engine loading needed, it works very well. So the low engine speeds are a work- around.

BMW K1300GTs' cruise control works very well in all gears, and at all speeds at which it will engage. This is because of course the CC is optimized for both a motorcycle and that motorcycle in particular.

So the Rostra work- around is a real world situation, not ideal but sufficient that one can use the CC down to very low vehicle speeds if one chooses: I often use mine below 30 MPH riding on coastal roads in the summer 'cause the 'street revenuers' are out in a big way.

As far as lugging the engine, I guess I am just not interested enough in that topic to [discuss, argue, defend or even address] it. Whatever the individual believes works for me- in fact, I think I remember reading about one famous gentleman who said something like 'I would rather die 1,000 deaths than lug the engine in a C-14'. Oh, wait, that was R.E. Lee going to surrender to H.U. Grant.... but I betcha' he would have said it about his C-14 had he been asked.  I did lug the engine in a Gravely T-8 once, and it was pretty awful: in fact, that tractor only ran another 20, 25 years before its owner died and I lost track of it.... pretty horrible stuff, huh? Too bad too 'cause I really kind of had a soft spot for that thing: it was ancient but really performed well and had more attachments than you could count. One of them was this unguarded snow blower, commonly known as 'the dog catcher' (for obvious reasons) that was an absolute brute to run. Good old fashioned American craftsmanship with lots of cast iron, thick steel and bearings throughout (no bushings, no sheet metal). I think you could grind rocks under the mower deck without denting it! And it had this really cool, optional sulky seat arrangement so you could ride behind it although it did make backing up interesting (an articulated seat arrangement). Ah, fond memories. But I digress- where were we? Oh yeah, BMW's suck.

I am glad you like it here, I do too.  And since you have been around long enough, you know that no such "war" would ever occur here.... certainly not with me involved, anyway.

Quit trying to be rational and such :)   In any case, I do not disagree with most of what you are saying... although I do heartily disagree with the owner's manual's shifting chart.   And it wouldn't be the only thing in the manual I disagree with either.  Of course, each to his own.  My C14 shutters and sounds like it wants to throw up in crazy high gears at slow speed and of course has zero response, all combining to make a pretty miserable experience.  I hate the way it feels and sounds, and that is enough evidence for me to call it "lugging"... as to whether it is actually lugging or not or doing any damage or not, I don't know; it was just a label I threw at it.   Brian seems to think not, and that is probably good enough for me... but not good enough to keep me from avoiding the situation :)

Still, I doubt I am alone in imagining some type of pain the machine might be feeling in such situations (anthropomorphizing aside).  It is a shame the Rostra can't deal with the lower loads/speeds more elegantly; it still sounds like a good system, even if it means just not using it at low speeds/loads if the user is so inclined.

There have been several times I've set my Rostra at 25-30 mph.

I have usually had it in 5th gear at the time.

Mine works pretty well w/o surging at those speeds.

Now, I originally set my dip switches up exactly as Brian suggested in his tutorial.
After about a year of use, it began to annoy me concerning how long it seemed to take to engage at a set speed. I have a friend that I installed one on his GS. He told me one day he had observed the same thing with his, which bugged him as well. He read up as to what each dip switch setting did, and had changed his #2 switch from off to on. This made it engage a lot sooner. Big improvement.

So, I changed mine, and had the same result...with one exception; Mine now takes spells surging.
It seems to be controllable, though. I have to watch about not engaging it if I'm going down a steep grade, or climbing a hill, etc. Otherwise, it has been an improvement.

Excellent! Welcome to the world of closed loop control.  ;) What you did was to shorten the time the Rostra uses to close the loop, which makes it respond faster. That is a good thing when the unit was responding too slow but a bad thing when it surges. It is not a 'right or wrong' situation and some other people have used different setting that they prefer also. The settings I used are quite forgiving and 'soft' for lack of a better word but the result is the system can be sluggish in some circumstances.

This is the root of the problem with the Rostra on high power- to- weight vehicles; it was not originally designed to work in this envelope. All loop closure systems are a compromise but there is a window where a given system usually works very well and a C-14 is outside the Rostra's window.

As always, the Rostra install has become a community development thing and a lot of people have contributed different methods, settings, etc. Lots of different things work, some better than others, especially depending on what the particular person wants or expects. Good on ya' for tinkering and getting a better machine as a result.

Thanks, Bro! And, thanks again for your cool tutorial. Because you took the time to document your pioneering adventure for the adaption of the Rostra to a C14, it has been a huge help, not only to me, but many others.

My friends and I will always be grateful to you, Brian.
My Rostra's been the coolest $300 farkle I've added so far.
Couldn't have done it without your help.

Because of you, I've been able to help several others install theirs, and they absolutely love them!

The last one I've done was just last month. I put an Audiovox 100 system on a 1999 Honda Valkrye.
(1500 GW 6cyl carb'd). It took me 2 years to convince my friend to buy one.
After we finished the install, we went on a 60 mile test ride. He was like a little kid with a new Christmas present! Even after he left my house, and headed home 35 miles away, he called me back to thank me repeatedly, saying how much he loved it.

I told him the real credit was due to you, Brian...for figuring it out.

Another friend that I put a Rostra on his GS is still thanking me... 2 years later!

I really appreciate your contributions to the forum.
It's helped me help others. That's what it's all about...right?

Thank you for the very kind words.

And it is great to hear all the positive feedback too because before I 'published' (posted it on an Internet forum.... not 'real' publishing), I was pretty wary of liability, real or imagined, and people getting cranky if they had trouble with this project. It has been something like 5 or 6 years now and so far, not a single complaint- my collective thanks to all the humans out there. :-)   To be sure, some folks have struggled a bit here and there but to the best of my knowledge, no one I have had contact with about the Rostra has failed to get one up and running.

Yep, the forums are great avenues for sharing information, and even getting to know new people and having a few chuckles. Unfortunately, they do need to be properly monitored and limited or a handful of 'missing link' types make a mess for everyone but that said, they are still the only way I know of for a given community of people with something in common, to shave information, ideas and so forth regardless of distance, time zone or anything else. The last limitation is language but quite a few people blow through that barrier too by speaking the language of the forum, usually English, and some do it better than some of the native language speakers.

Actually, it was a compliment to some members who did not learn English as a first language, not a knock against anyone else. And certainly not you. Just a comparison. I have the greatest respect for anyone who not only 'knows' a non- native language, but actually commands it and uses it well. Not an easy task, at least in my own personal experience (I can hurt the ears of both Germans and Dutch speakers.... and amuse and disgust them all at the same time :-(   ).  And occasionally, there are those who command more than two languages, such as Martin: Spanish is his native language I believe and so assume he speaks that well but he works in Germany so again, I assume he speaks German well and I know his English is excellent. Now the thing to remember here is that Spanish is very different from both German and English so learning those would be more of a challenge than, say, Italian or French which share the same language base (Dutch and English are Germanic languages, very different from the Romance languages).

I think Brian's guide is still the best one out there.

 By the lit switch, (I think they are all back lit) I assume you mean the one with the "Engaged" light? I didn't get that one but I did add an engaged light of my own a year later and I think it's worth having. Mine works fine, but yes if I were to do it over again I'd spend a few dollars more and get the switch with the engaged light on it.

The Murph covers work well for the front of the switch, and I used Permatex Ultra Grey (mostly for color matching) around the perimeter where the back of the switch is mounted to the metal plate I mounted it to. I also have a rather ugly mess of the same silicone on the rear where the wires go through the metal plate into the switch with a black split tube wire protector over them and more silicone around that. I later put some black Sugra over the silicone on the rear wire entry just to make it look better. So far no water problems and I've ridden in rain for many hours. I think Brian opened up his switch and filled it with grease (dielectric?) so there was no way for the water to get in it.
Title: Re: Testing the Rostra cruise control
Post by: C14lvr on February 26, 2015, 11:14:28 PM
I suggest you order the switch with the engage light and remember to get a second relay for it.
Uses the same relay as the one for the brakes. Get it from Murph.
My friend didn't listen to me, bought a used one off Ebay, then found out you can find a normally open relay everywhere...but trying to find a normally closed one's a lot tougher.

2 reasons I prefer the switch with the engage light...
1) there have been times I've thought sure I pressed the button hard enough and correctly, it didn't engage, and a quick glance tells me I didn't because the lights out.

2) if you ever have a problem with the system, it's a clear indicator if it's a mechanical problem or an electrical issue. Makes it quick and easy.

It's just nice to have a visual indication when the cruise is engaged.

Oh, and silicone's your friend here... Pop the switch cover, coat it good, replace, make sure the seam in the cover's sealed good, and pay close attention to the back where the wires exit and seal there good.

Brian's posted pics of previous switches he's had to replace from corrosion.

Mine's lasted 3 years with no issues so far, and I've ridden in lots of rain.
But I also live in Oklahoma... Brian lives up north...

I went through a few switches trying to use silicone sealant to make them waterproof. In the end, I just used a heavy coating of grease on the pc board inside the switch, left it unsealed and have had the same switch on the bike for at least three years. Still carry a spare on long trips though- once burned, twice shy.

By the way, there are two different types of switch out there: one has Klixon type switches; these are small 'pop discs' that flex to make the switch contact. I have never found a suitable solution to make these corrosion proof. The other type uses the P.C. board itself as the contact, and the back of each switch is has a conductive pad on it so when you press a button, it shorts the P.C. board traces. These switches respond very well to grease, which makes them virtually corrosion- proof, and the switches work find right through the grease.

I used the non-lighted, no engage light, control pad that came with the Rostra from Murphs kits out of the box. No grease, no silicone, mounted to the top of the left handle bar and it hasn't given me any problems.

JS_racer,
When I ordered mine 2 yrs ago from Murph, at that time if you requested the switch with the engage light, he would swap it out with the standard switch he usually puts in the kit at no extra charge.

Not sure if he can still do that, but he did it for me, and it was much appreciated.
He has to go through a bit of extra trouble to order that particular switch in.

Maybe Gary might see this, and be willing to chime in?

Don't forget to get the second relay, too.

Once you get this thing installed and working, you'll be asking yourself how you ever got by without it!

They're an awesome upgrade. Well worth every penny and work.
Enjoy!
