thanks for the post. dont let me detract you. Just wanted to point out other options.

Would you care to go into more detail about this? I would like to go this route, not going to race this car in 1/4 mile or Indy tracks! LOL

no jack.

THIS crude mod , will cause bogging and save gas.
it will stop all jack rabbit starts or power shifters.

you can add series resistance to it, but not too much as it will throw a DTC
for open TPS. 10kor 15k, or higher is trip.

each car is diff in the opens fail trip point.
same with low , or shorted to ground TPS.

1 part a cap
or 2 parts a series resistor and a cap.


the ecu see the rate of change as enrich mode.
so just slow the rate of change.
the cap oppose a change in voltage.
