I'm having trouble with my TC lock up on my i6 converter and I don't really knwo what to change. It locks out as soon as i completely let off thr throttle... but not before that. Its really annoying.
Any suggestions to help a n00b figure this one out... I know this is a really mild converter, but I don't think much of anything was changed for lockout on the tune.

Yea well I got the converter in yesterday and fired it up today. Yeah it definately needs a retune shift points are everywhere and it doesn't wanna stay idling when coming to a stop. Is this normal

yeah when cammed you have to retune the idle portions. less rotating mass lets the rpm's drop faster (kinda like a lightend flywheel in a stick shift) and the computer can't compensate in time. this has to be tweaked out in the tune. shift points can be off do to the converter reving higher at the same speed as stock.

lets try this again. because you are cammed (which is hard to make idle anyway) then you add the light weight of the converter allowing the engine to drop rpm faster after throttle lift they wind up dying more. so yes you have to tune the idle cells. i'm in the deployed to the desert so i don't have my tuning computer with me to talk you through it exact. but try adding a little raf (iirc) air just to hold your idle better. (cheater way) the from there make your adjustments to idle cells. sorry i can't be of more help, with out my computer i can't remember all the tables.
