Hi
I swapped an 8.1 from a 02 2500hd into a 78 squarebody, I used the original PCM and TAC module, I bought a Tac harness and pedal from PSI conversion. No throttle mapping has been touched because the warnings make me nervous I will brick the PCM.
So my issue is that I get 0-178% pedal position in VCM scanner as I depress the pedal to the floor, I get 0-100% TPS by the time the pedal position hits 68%, So basically I get full throttle by the time the pedal is 1/3 of the way to the floor. If needed I am going to go get a 02 pedal but I would like to fix this if I can with remapping.
I will attach the tune and if someone has an idea I would really love to hear your feedback.
Thanks
