I got a lsx conversion 1975 car, with a 2013 6.2L E38pcm.
The transmission was OS swapped for a T42 A4 unit with a 4l80e transmission(by another shop).
Problem is sometimes if you floor it, the tps % won't go WOT sometimes and the tps% chart line will be wavy and timing pulled intermitently and then eventually will go to 83.9%. I deleted all tq management transmission side. I logged "etc torque management type" and when the tq management(timing -15) occurs it reads "trans". Not sure what trans tq management table I missed?
Could the ECM be activating the fast torque exit which I thought was a an A6 function but the tcm os is for a 4l80e?
Or maybe I missed some tq management. I am human.
Another side note: When you turn the key on the tps% reads 30.2%, when you press the pedal to the floor, it reads 83.9%(normal), but when you release it goes back to 18.8% tps. Then if you press the pedal to the floor again, 83.9% tps, then release, it will go to 30.2% tps and hop back and forth from 18.8 to 30.2%.
Sometimes you drive it and go WOT no problem, no tq managment 83.9%. Then sometimes tq management trans type.
