I'll prolly rig something out to test this once I get a Scangauge from the group buy to test it out. At some point it will set a fault, but I'll just reset it and increase the with a pot. I heard there is a performance Cat for my car I can put on that could help with the NOx if this works out.
My theory is that the scangauge will be spoofed by the IAT resistor mod. It's algorithms (most likely) use the IAT sensor to extrapolate MPG.

I really gotta do that experiment. I am soooooooooooooooooooo lazy sometimes.
