First off, I am new to the forum and DID try to search for what I need answered. I've had my car for about 3 weeks now and really like it so far. I was just wondering if there is a way to calibrate the DIC? Basically my "fuel used" is off by about a gallon and this also affects my MPG reading on there. My car is a 2001 GTP sedan with zero mods to my knowledge.
