I didn't use the delta map table because my map goes from 77 to 100.1kpa immediately. Looking at the log, it goes into AE right away so I feel off TPS is best.

I'm still trying to play with converter lock. There is this like. 1/2 second delay when I mash the throttle from when the pedal hits the floor, to when the RPMS actually kick up. If I back AE off it lean pops, so I don't think it's a rich bog. Timing doesnt seem to fix it either way so I'm thinking it's either converter lock, or something else mechanical.

Again, MAP peaks to 100kpa the millisecond the pedal moves so I don't think it's MAP sensor lag. I think the motor is just loading up too far below the cams powerband because the converter is locking too early, even though It shouldn't.

Theres just nothing I can do to tune out the lag. With the 2:59 rear end, even in 1st (3.06 if I recall) gear by the time the converter locks the car wants to be going 30mph from a dead stop. That just aint happening.

Guess i should get something in the mid 3's for rear end gears.
