M6 car. In gears 1-3, DFCO works fine. In 4-6, it doesn't seem to want to enable. The map readings are similar in decel in each gear (~19-21 kPa). The RPM/speed/TPS/MAP entry values are all met.
In 4th gear, ~2800 RPM, I let off the throttle and IPW flatlines to ~2 ms, spark is pretty stable and drops slowly as the RPMs fall, but it never enters DFCO. AFR goes rich.
Is there something else I should be looking at here?
