I just did a trackday and the bike has started to become really choppy at 4k rpm or below.
Might be doing it while on the track but it is harder to notice. It does pop a lot through the corners.
I am not sure if it could be the Power Commander, the Fuel Pump or the TPS yet.
I was going to pull it apart and hope it is something simple but would anyone be able to loan me a Stock ECU, TPS or Gas tank/Pump should I need it to test?
What year is the bike? I may have a stock ECU for a 2008+ laying around somewhere.
That would be helpful wouldn't it?
It is a 2008. I see some guys online had a similar issue and it was one of the fuel injectors.
That would be strange though seeing how low of miles it has.
Thanks Paul, if I need to test the Power Commander vs a stock ECU I will get with you.
Why are you riding below 4k on the track anyways???
Cause riding through the pit at 60mph is frowned upon.
I bike idles fine, I just can't ride it in the pit without it jumping a lot.
I can hear it popping on maintenance throttle in the corners.
This all started in the last couple sessions.
Lol I'm just messing with you. Sounds like a tune issue. Is it fine at wot? Try taking the pc off completely? You don't need an ecu to see if the pc is bad.Quote:

the PC could be going bad, which really sucks, I have heard that is common though.
If it just started happening with no change to the tune, I would look at hardware failure rather than software.
I had that exact same thing happen during a,trackday on my gixxer. Turned out one of the bolts to the airbox had come loose and it was sucking air through the seal. Just throwing that out there
Everything is fine at idle, it is only when its under a load does it get jumpy.
All the cylinders are getting hot.
I pulled the air box and figured out the new sound.
The throttle bodies flutter and vibrate when everything is powered on. It will keep doing this until its started.
So TPS or throttle bodies?
My GSXR had a similar issue with a PC3. It ended up being the ignition module.
Sorry.....way late to the party...
Ignition coil. These crap the bed from time to time. I don't chase them...I replace them all.
Did you find what it was??
No I couldn't replicate the problem.Quote:

I unhooked all the PC stuff, rode it and it was fine.
Then I hooked it back up one unit at a time and nothing.
I believe it is in the PC somewhere but can't prove it.
I ended up soldering in the PC power cable, even though while testing the clamp was working fine.
The throttle bodies will still make a lot of noise when powered on, but not as often as before.
I am going to listen to some R6's this weekend and see what the deal is.
Well I know this won't help much...
...but...
as my grandpappy used to say; never trust machinery built by a country that never won a war...
I was really hoping ignition coil, but they were good.
The bike only has 7k miles on it and the engine has only about 1,000 miles.
I am guessing it is a connection issue.
