This may be an old rehash of previous posts but I have an idea that just might work.
The old trick of using a resistor to replace the IAT sensor and fool the engine into thinking it was always 40 F intake air temp, so when the temps rise, the PCM does not retard the timing to control predetonation.
We have been told that this could be more than 2 degrees along with leaning it out.
It usually only works for a very short duration until the engine learns thru other sensors that it really should retard the timing and thus over-rides this trick.
I believe these other sensors to be knock sensors.
So if the knock sensors don't detect any knock, then the trick should work.
Are you catching my drift.?
The real trick is controlling the other variables by cooling the engine thru other means
So by using the trick to fool the engine into believing it is ingesting cooler air, it should run richer and full advance timing.......and if you are intercooling or boostcooling you should see a gain in power.
Love to hear some arguments.
