Many of you are bored with my slow progress, but I finished my 80e swap in my 02 Yukon with a 5.3.

Can someone review my tune to see if I've got the 80e dialed in OK? The trans is internally dual fed and thats all the mods done.

I did my best and think I set my shift times to 0, and removed tq management.

Thanks!

 

Not much to trans tuning

0 tq mgt
0 shift times
Approx 10% over base pressure with max line pressure at max torque input
Tcc pwm 99 min 100 max

 

Thanks! I figured not much had to be done.


Side note, the 80e shifts entirely different than my 60e. The 60e had a vette servo and was tuned. While the 60e shifted fast the shifts were more clunky, still with a slight pause because of the remaining TQ management in place. That and I think a band engaging on one of the shifts.

The 80e with all those changes is damn near seamless on gear shifts. Its fast. Totally worth the 40lb? trans weight gain.

 

This stuff?

That 90psi should be 99?

Upshift (norm, perf) are the ones to mod?
