I have a E38 LMG with AFM and was wondering if the PCM will sill revert to the Active Fuel managemet timing table even if the DOD feature is disabled via the tune? In my high octane spark table my highest timing value is 33*. I did a log the other day and noticed that it was showing 40-47* at light throttle and low load conditions. I looked at my AFM timing table and there are values that high so im guessing the PCM was using them?
Second, when in closed loop my commanded AFR is 14.68 at the start of my logs. When I finish logging I noticed it had changed from 14.68 to 14.17 to 14.30 to 14.19 to 13.67 to 14.43 to 14.01... Is it supposed to change that much... None of this was WOT, just light to medium throttle.. Where can I find the closed loop commanded AFR in my tune??
