resistor

[Camarokid]

ive seen many ads that you can get 20 hp by putting a resistor in your car, is there any harm this can do to your car, will it kill my gas mileage, and is it easy to install?

It will trick your car to think that the air entering is coler.... thus making the car dump more fuel into the engine.

DON'T do it

Your better off just leaving the thermoresistor on it (IAT). I have played that route, and you dont notice any difference at low speeds even palying with different values. Not worth it and a waste of time even messing with it. -Tim

not quite...theres an iat timing adder table in most code...basically what it does it takes your stock spark value at any given cell but lets say 25* timing and then the adder table can either add(obviously) or subtract timing depending on the iat reading. Most cars that ive seen only subtract a few * at higher intake temps. My gtp for instance would pull 1, 2 or 3 * of timing advance dependant upon iat temps & only if they were over 104* and it would pull more as the temps went up. Dont get me wrong there might be a fuel adder/multiplyer in the code but it doesnt look like its used in the v6's and i think the v8's its visible but in most cases isnt used. But yeah in the dead of summer when your at the track & your intake temps might be 150* the iat is probably pulling some timing...maybe 3* maybe 12* depending on what OS your running...ls2 files pull up to i think 12 or 14* with the stock settings whereas ls1's only would pull ~3* tops. Can you say detuned?
