Strange Part Thottle KR

Post by jacobs53 »

I have been performing some additional logs and noticed some KR when coming off part throttle and in CL mode. I understand that the ignition timing is advanced until either it reaches the value defined in the max ignition timing table or until KR is detected. For both logs that I have taken I am seeing 4.57 degrees KR and 2.81 degrees KR, this only lasts for approx. 1 second - however, I'm a little concerned about the 4.58 degrees KR value!!!!

I'm sure some KR at part throttle is normal but I haven't got any reference data for the standard map, however I would expect it during light acceleration not coming off the throttle and decreasing the engine load.

Is this something to be worried about?
