Do the same thing you did on the old ecu.

Why'd you have to replace your ecu?

Hmm not sure what to tell you man. 00-05 ECU's cannot be reflashed, only 06+ ECU's can. So thats out of the question.

Well then let us know what supercharger kit it is so we can figure out if there's a box that is separate from the ECU for the blower.

doesn't sound possible.

what pulley is on your kit. Stock basic comptech kits have a rising rate fpr and you don't tune them. if your on a stock ecu this is probably what you have

You can kill the 02 sensor heater drivers by plugging the harness into itself instead of the sensors.

The ESM used with a comptech is wired to the engine harness, there is nothing to be done to the stock PCM other than programming the keys.
