Guys, A Colleague at work has 2 of these mod-chip resistors .
He fitted one on his C2 vts and we did a before and after comparison,
The only difference was the initial throttle response was alot sharper and mid-range felt a lot perkier. "This resistor fits into the IAT sensor and fools the ecu into thinking there is a lot more colder air coming in, so the ecu ups the timing and fueling a little" Quote from my work colleague.
The resistor can be taken out whenever he likes, He gave one to me so Im going to fit it But After a search on here I couldnt find out where the IAT sensor is on the 2.0 16v. Please could someone shed some light??
Thanks
