I've done some research about adding a resistor to to the IAT connector as an MPG fooler. Is this an acceptable method? I wonder if it can affect anything in the engine when the outside temps are cold and the IAT is set at 143 degrees.
After thinking about it for a while, I bet an arduino could be used to ramp up the IAT while monitoring the ECT. That could be an easy thing to do with a few relays and different resistors used to change the IAT. Say when you start the truck and it's cold out, a relay could close and send the actual IAT temp out. As the truck warms up, other relays could open/close and send out different resistor values.
Any thoughts on that or could I just use a single resistor in the IAT connector? I wouldn't mind trying this on my trip to Texas next week.
I put an adjustable resistor in mine a few years ago. I set it at 143 degrees. I check the resister every couple of months or so to make sure it hasn't changed - so far it has remained steady. It h
