i bought a eaton m-45 supercharger for my 2002 pontiac sunfire GT. i bought it already installed on a car and i put it in my current car the sunfire. i cant go to the dealership for a calibration because they said the code was downloaded already on the other car. is there anything i can do i wanna get the most out of my supercharger i need it re calibrated .

ask the dealer to reflash your ecm. they CAN do it. if they say no, take it to another dealer.

Swap ECMs from the car that you got the S/C off of....




its an old concept. time for something new to take the reigns. - Z yaaaa
