[QUOTE="Mr_Canoehead, post: 1248608, member: 86927"] In my case, adding the O2 fooler with PC-V caused the ECU to start running leaner and leaner until it was absolutely unrideable in the closed loop area. If I reset the adaptives by disconnecting the battery, the bike ran great, then started to run worse and worse again. It took a couple of hundred miles to get to be unrideable. It is surprisingly hard to run a 1300cc bike outside the Open Loop area to get home! My theory is that the O2 fooler was somehow giving the ECU a slightly rich signal and it was adjusting to try to get back to where it wants to be. [/QUOTE]
