Kind of right. Timing in itself is not a big power adder in any way, shap, or form. Though the stock parameters for all factory engine have a lot of room for advancement at some points; throttle responce is the main gain from increasing timing. Not power. The point of this is not to get a .5* or 1* of timing advance. That's 100% inconciquencial. The point is to get the extra fuel.

Can someone explain to me what exactly does "advance timing" does? Toysrme, do you have any pictures of this mod?
when each piston reaches a certain point in its travel the ECU tels the sparkplugs to fire -This is timing. If you advance the timing you tell the plug to fire sooner thus getting a better compressed burn on your fuel, and a more complete combution stroke.
I haven't looked under the hood yet but , how do you wire the pot? It has three prongs right? And how many leads are coming out from the sensor, if there are two, which one do I choose unless there's only one.
The wire you want is the signal wire coming from the ECT to the ECU. If there are 2 wires coming from the ECT, 1 will be ground and that will be easy enough to figure out. What you do is cut the signal wire. Then connect one end of the wire to one of the terminals on the outside of the potentiometer and the other wire to the terminal in the middle of the potentiometer (variable).
The way potentiometers work is, if you measure resistance accross the outter terminals, you will get the value of the potentiometer, in this case 500 ohms. If you measure from say the left terminal to the center, the resistance will vary as you turn the dial. Connecting left terminal and center terminal might make resistance increase as you turn the pot clockwise where connecting right terminal to center would make it decrease in resistance when turning the pot clockwise. Your best bet is to measure it or refer to a diagram that frequently comes with them. So again, you don't do anything with the ground wire from the sensor, you are only adding this variable resistance in series with the signal wire. -JoeB

If i get this straight I attach a 500ohm potentiometer to the ECT wire leading to the ECU. I then start the car, preferably drive for a while until I reach a stable idle, then start turning the potentiometer until my idle RPM increases to ~1100rpms. My car has a very low idle at around 500rpms after I get off the freeway, so do I need a stronger potentiometer?
What if the ambient temperature was below that of the activation point for "closed loop", sorry for bringing it up, will the rpms still increase as I adjust the potentiometer?
EDIT: is there another way to advance a car's timings?
