Default tuning question

for some reason my car is kicking out of lock up ( trans ). a sponsor here told me to raise the missfire tables because that was a common issue for my problem. well, i did that, well had it done, and the problem is still there. can any1 help with my problem? it seams to do it more at lower speeds than at higher speeds...also, no codes are being set....

Has your lock up speed been raised since you got the stall?

Had the same problem after my cam / TC install - bumped the misfire tables to max and problem went totally away.

i bumped mine up by about 30% total and my problem also went away, you dont want to disable it completely for safety.and even though you didnt get a missfire code doesnt mean you not getting any missfires. have him do some datalogging with the missfire pids selected for every cylinder. i bet he'll be surprised to see missfires despite not setting a code.
