Ok, so first just a little background of what we are working with...We have an 06 vette LS2 going into a 69 Firebird followed by a 4l70 and all wiring and computers are set up for a 06 TBSS w/LS2 and we are having shifting issues. I have looked at the diagrams and found that the logic inside of the throttle bodies are different and I believe that its causing my TPS% to peak at 39% throwing off all of my shift tables. According the the help in the program I should be able to go in and reset the values that the computer sees as idle and WOT. I have attached my tune in case there are any questions. My question is where do I find the parameters and has anyone heard of this swap before. I know the easy thing to do would be to buy a TBSS throttle body but if possible I'd prefer to use the one out of the vette.
