Anyone have a list of resistors used to put in the IAC to change the timing, I hear by changing the resistance you can add or pull timing some.

Anyone have any info?

 

i think this was advised against, but i maybe wrong, nonetheless i'm pretty sure it is a 4.7k ohm, 1/2 watt resistor

 

By setting the IAT to a set resistance value, you car will run rich and add timing, this will kill performance. The best way to add timing for powr is to strap it on a dyno and use an editing software like HPTuners to achieve the best power. You can go to far and add too much timing will decrease power yet have no audible knock. I would highly advise against it.

 

You can use a potentiometer in conjunction with a good wideband, and adjust as needed. By adjusting the voltage released by the potentiometer pull and add timing as needed.
