Hi all,
I am working on a 1999 k2500 chevy pickup. I swapped in a 12 valve cummins and built up the 4L80e. Im using the black box ecm to control the transmission, cooling fans, and A/C etc. I have used HP Tuners to get the transmission working pretty good. The problem I have is that I have not figured out how to get the ecm to make an engine torque calculation and the line pressure rise is based on torque. Also have a few things on the torque converter lockup control that is not mapped out in HPTuners. I have the user defined parameters feature in HPTuners if i could find an XDF that would be applicable i might be able to get a few more things ironed out.

If anyone has any knowledge or information about this ecm/OS i would be grateful. Thankyou!!!
