Installed my PCIII the other day, along with a Pipercross filter. After a day or two, depending on what map I used, the bike would occasionally stall for half a second at low to mid rpm with low throttle opening mainly 2nd or 3rd gear and then get going again, which actually was kinda scary first time (middle of a roundabout). Messed around with the mapping to see if it made any difference, which it seems it did.
My kinda ordinary gear:
GPR slip-on installed when new, by dealer
When I use the PC map for european models with GPR slip-on it happens now and then, maybe once per short trip.
When trying a custom map from the forum (although a dyno-map for a full arrow exhaust etc etc) would stall it 4-5 times per same trip.
to get it to stall around the rpm/throttle opening where it usually does is not easy, so it's kinda sporadic as well..
Does the supreme collective knowledge of the forum have any clue as to what might be causing this? I'm not sure what you call this phenomena though, I've tried searching for stalling, hiccups, stuttering, and so on, but no one seems to be having my problem or at least not in the same way. If the problem only lies in the mapping I'd just have it dyno'd, but first I want to make sure that it really is, since a dyno is around $330 over here.
Thankful for any and all input!
