Just curious what the resistors are doing to boost horsepower when connected to the coolant switch on the honda accord engines. I thought about buying one on ebay but I am not sure if it actually will work or is it some type of scam or what?

 

Surprisingly, The only things I will buy from EBay is used items (cluster / switches etc). And everything else I look at with a jaundiced eye.
The only thing that a resistor inserted into the temp sensor circuit would do is fool the ECM into thinking the engine is at a different tempurature than it actually is, thus shifting the fuel curve. It's a band-aide approach at best, much like the most recent advertised "instant 35hp Increase" product out there.

ya dont buy one if i remember correctly they sell those resisotrs for like 12 bucks on ebay. I think you can just go to radio shack and buy some for "cents" anyways it doesnt work trust me, friend was fooled in to doing it to his chevy check engine light stayed on
