S1000rr hesitation w/ PC5?
Hi - I have an S1000RR BMW and am experiencing a bog or hesitation hesitation in acceleration that seems intermittent and also occurs when rolling into the throttle while accelerating off the corner.
I have been looking for others who have encountered this gremlin. I can't get it to reliability repeat, so sometimes it does it and other times, in the same conditions, it won't hesitate. This is very puzzling, and I have not had other people say that this is a problem they are encountering. For the sake of comparison, My bike has an AK Evo full exhaust, a PC 5 for fueling correction, and several hours on the dyno tuning the motor + the TC ABS and quick shifter.
The problem usually occurs when I am throttling up in the corner exit between 5000 and 8000 RPM. I am moving the throttle rapidly, and the problem(bog, miss, hesitation) occurs as many as 3-4 times in a row (Most often once) before the bike clears up and runs. I have the same problem when the bike is in the slick mode and the race mode settings of the traction control.
I have been speculating that the addition of the PC5 may introduce an extra delay into the EFI computer's throttle position calculation for the ride by wire throttle. If this was happening, the bike may be getting a throttle movement command that is not synchronized with the fuel injection pulse, a little like the old slide needle carbs when you opened the throttle too fast.. Of course, I may be out in left field on this, but the problem is real and very annoying and distracting.
Have any of you all had this problem? Could this be a problem with the PC5?
I am looking for other ideas! Thanks!
