Anybody know what this $10 resistor does? Maybe alter the temp sensor signal so the computer thinks it's cold and runs rich?

 

That's exactly what it does. :roll: You can get that same resistor at Radio Shack for $0.20 or so. To figure out the value, look at the FSM testing procedure for the temp sensor, and pick a resistance value off the temperature chart for the sensor representing 160*F or so (assuming a 180*F thermostat). I doubt it will net 20hp as he says, and it may not work at all, but that's all the guy is selling, a $0.20 resistor at a 5000% markup.

That line about using premium fuel is junk too, unless he means good-quality fuel. Unless you have a high-compression engine, higher octane will not do you any good.

 

In fact, LOWER octane get you more horespower. Octane additives slow the burn and prevent pre-detonation associated with high compression.
