Allison 5sp: Logging For Transmission/ECM

[RobsDmax]

I have a very hard time with the truck trying to do a burnout, it literally stops on the 1-2 shift, what should i log and look at/ what should i change to fix this. Thanks

Make sure the changes in your torque section of the ecm are made so that way when it comes up quick on rpm it wont hit a fuel limit...or be limited by the torque limits within the parameters section. On the tcm make sure the torque table doesn't start cutting your fuel @3400rpms, if so just copy and past from there down. On logging- see if its cutting MM3 when it falls out. If so, check the sections I just named in the ecm and tcm at which rpm it hits the limiter.

Good luck,
Kory
