L76 swap in RX8 dies when I come to a stop sometimes LOG FILE INCLUDED
Can anyone tell me why this L76 swapped in RX8 with 6l80e sometimes dies when we come to a stop? First log file we have done, hope we have included everything you need to see. Wideband is also logging.
you have no VSS input to the car by looks of the log
without that the car is using adaptive idle only to maintain idle during any no throttle pedal command. adaptive idle isn't sufficient to maintain idle during coastdown and dynamic airflow changes present in your fault.
without a VSS you have to reach a compromise and understand DFCO will not activate. this means all the high vacuum areas present during coast down need to be spot on as too lean or rich will make maintaining target RPM challenging for the PCM. looking at your wideband and VVE table 3D shape it could use some work. it may also be worth targeting a higher RPM for idle.
bank 2 LTFT is doing weird things too. might be worth disabling LTFT and using only STFT
