"17 Tri going into an almost Limp mode 4 times now Help
#2
well, first things first, start at the beginning...at what mileage did he go with the PV and at what mileage did it begin exhibiting this behavior..how many miles did he ride it completely stock and did it do this during that period? want to rule out any obvious direct correlation between the timing of the problem and after market tuner install for initial troubleshooting right? if it behaved normal stock, then didn't after ECM changes, I would think the next step would be to restore ECM to factory settings and see if the problem disappears.....doubt the dealership would pick up the tab on that tho...of course it may be something completely different that others here may have seen or heard of and will chime in..good luck

mjwebb my name is azjohnryan and it is my bike that santajim posted about. When I first attached the powervision at about 2000 miles I was using it for gauges only and had made no changes to the computer and all equipment on the bike was stock. We were on a ride to the East valley when this first happened and I had to limp the bike back to Phoenix watching the engine temp on the powervision to keep it from getting too hot. This time it was still having power loss the next day when I took it into the dealer. They had it for a couple of days and when I went in to pick it up They said that there was nothing wrong with it. The only thing they did was update the ecu map from an A map to a newer B map and they assumed the map had become corrupted and they had it fixed. I do not think they diagnosed any components. It was not fixed. This has happened a total of four times now with both the powervision on and off the bike. the last three times it did this after the bike returned to room temp the problem resolved on its own. It has never thrown an error code. After the third episode I replaced the spark plugs and thought I had the problem fixed. It ran great for about 300 miles then crapped out again. I let it cool off for a couple of hours at santajims house then it ran fine coming home, aprox. 30 miles. This is where I am at at present. I do not think the dealer can find the problem without error codes but at the same time no error codes the way the bike was running is a very big clue. What do you think?

It is my riding partners '17 Triglide.
Let me throw some info at you guys and see if any of you are having the same issue and what they have done to cure it.
4 times now we have been riding along and his bike will start running rough and lose alot of throttle control. It doesn't go clear into the "limp mode" because he can still get the bike to run at highway speed but the throttle looses the roll on power like when it running right. He has a power vision on the bike and the head temp will run way up and the coolant temp too but dosen't puke fluid. We will pull over and stop and the engine is running very rough almost like the etms has taken over but it is dis enabled. After it has cooled down it will "fix" itself and run fine for a while and then it will do it again. He has had it into the dealer each time but like I said it will fix itself and the strange thing is it never has thrown a code of any kind so it makes it hard to diagnose. We have gone over each of the systems and tried to figure it out ourselves and every time we think we have it dialed in it fools us.
Yesterday we were coming home from Laughlin river run and had put 400 miles on and it started again so he called the dealer and this time they want him to write down everything that has happened so they can take the info to the MOCO but I am asking all of you out there has anything like what I tried to explain happened to any of you and what cure did you find.
We are planning a 3k trip next month but may have to cancel if we can't figure this out. I have told him this thing is almost a Lemon Law thing now.
Thanks for any info.

Since it is still under warranty, and the dealership cannot replicate the problem. Next time it happens, take a video (with audio) of it...also show the PV engine temp read out in the video.
That way they know there is a problem that needs resolving, even if they cannot replicate it, they have the video, and will need to keep digging until they find the issue.
Also, since it has gotten so hot, insist that they do a Leak-down test to see if the engine is still within spec, or if they need to do some warranty work on replacing parts that have been damaged from the heat.
You are in a hot part of the country, and these things run too hot for their own good. Once they get it fixed, under warranty, you may want to do some things to keep it running cooler. Here is a LINK with good info on the subject.

I personally wouldn't show a video or take a picture of the Vision anywhere near my bike is i was going to attempt a warranty claim. Why give them any reason at all to deny? The bikes covered, return it to stock form and let the dealer figure it out.

In any case, next time it happens video it...then make them fix it...or go to a different dealership that will.

Well here is a couple things you could try. Take the air filter assemble off and check to see if the engine temperature sensor it tight. It is located behind the Air cleaner assemble in the front area of the rear cylinder head. Just forward of the pushrod tube. If this is not tight it can do what you describe.
Another thing, if you can, is to try and cool the ECM. If you have a bottle of water and a rag, once it happens pull over and remove the seat. Lift the ECM from where it's snapped in place but DONOT remove the connections! Wet the rag and then wrap the ECM case with the wet rag. This will pull the heat from the ECM quickly, start the bike back up and see if its fixed. If so, you have a bad ECM and its failing under high temperature operation
