San Jose BMW has been installing Power Commanders on our bikes for a few years now and I'm wondering if anyone out there has been able to correct similar problems that you and I are having with one of them?
I've been chasing down the same problem on my 98 KRS and so far I've replaced the O2 & Air sensors that have helped out alot but the problem is still there when I closed down the throttle slightly, usually while I'm going downhill in the Mt's setting up for a turn.
I'm not sure what else I can do at this point other than go with a P.C. and put it on a Dyno and make a new map for it.
The price for a new chip or a P.C. are about the same but I'd still have to pay the for the Dyno time if I choose to make a custom map.
