Programming for bigger TC
Is there any programming required with a bigger converter to compensate for the added slippage?
I've heard a number of different responses, some say yes and some say no. If there is some programming required, what parameters would the settings be at with LS1 edit?
Any replies would be appreciated.
Thanks

It's not NEEDED, but I'd recommend it. I've drove my car after a converter swap before and after tuning and it made a nice difference. If you were to drive my car you'd know that I had a high stall, but would never think it's a 4400.

how much sooner should I set the upshifts? Would 5 or 10 mph be too much, or should it be a higher or lower amount based on the size of the converter?

FWIW, I made more changes changes at lower TPS than at higher TPS. The idea was too make the converter less noticeable at lower throttle positions by upshifting quickly. This strategy works well with bigger gears, less so with smaller gears. It'll take a some fine tuning. You might be surprised at the difference small changes can have at lower speeds/TPS.

Your going to wish you went higher.
Had the same exact stall until i rode in a 3200 stalled car.

Damn fingers...
I meant a YANK SS"3"600. Thanks, for fixing me.
