Buy the kit linked above. The developer put a lot of thought into it. He filters and traps the signals in more ways than I ever considered. The main function is to cut the AC compressor when the TPS voltage exceeds a preset limit.

But the circuitry includes a manual override, and three different modes involving high, medium, and idle TPS, interacting with vehicle speed.

Settings include multiplier value, adaptation setting (modifies the length of the cool-down period), logging period, and retrigger period.

The developer says there are 1500 lines of code in the EPROM. Way too complicated to do myself.
