Looking to see if anyone else has experienced this kind of off-idle timing dump. It only occurs when trying to take off from a dead stop in 1st gear. Is even worse after a long DFCO and the lambda is targeted for .95 (I've always assumed this was another form of catalyst protection that we don't have access to adjust) and I try to take off before it has returned to targeted command of 1.0. In both cases, the car literally falls on it's face and then recovers rather wildly, almost like the car is fighting a limiter.
Here's a list of things I've tried to remedy this problem:
1 - I've tried bumping up my MS in the off-idle cells, no change
1.1 - I then tried lowering the timing in the same areas, no dice
2 - I bumped the OS in the same areas as the MS changes, still the same
3 - I tried adjusting the DALs to see if that would help, nadda
The only other table I can think of to adjust to try and remedy this situation would be the optimum torque table. However, in the past when I would try to adjust this table, it seems I needed to go back and crank MS timing through the roof and it didn't seem to allow for smooth drivability.
Any thoughts?
