I tried playing with the IAT on my car. I actually found a potentiometer that could plug right into the IAT pigtail. I wasn't able to see any FE benefit or increase in timing, but the pot I found would only allow me to dial in an IAT as low as 40*F, so maybe I just needed to go lower. I can't remember if less resistance=colder IAT or warmer IAT, I would assume colder but I'm not sure.
