T42 4t45e e37 lap supercharged torque management killing timing in 3rd gear
So I have a pretty odd problem, I'll post a file and log today when I get home.
Me and the tuner are pretty stumped, car is pulling 7-10 degrees of timing in 3rd from the 'trans' under spark and rpm TM pid. It seems I can get full timing if I kill Reduction Duration, but at the same time that causes TM to come on in Neutral making the TB un responsive. So I'm left with a choice, running full 3rd timing or being able to rev in Neutral.. trying to find some middle ground where I can have the cake and eat it too here but not much luck.
Starting to think I am missing some vital tables in controlling TM on the T42 A4.
Read a few pages about 4L60/80s losing timing on shifts but this is a little different, under WOT I am losing about half my commanded timing from about 4000 rpm up (in 3rd)
... I know I can force timing by setting minimum spark TM but that feels a little greasy
