Hello all. My 2.4 with the GM Supercharger Kit recently started running rough. It sounds like it's choking and will die if put into gear. There is a new engine in it, so I brought it to the dealership because of the engine warranty and they said it is either the coils or the computer controlling the coils/ignition timing.

I have replaced the coils in the past, so I am familiar with the parts. But what exactly is this "ignition computer?" I asked if he meant the PCM and he said no, that this computer controls the firing times, etc. He didn't seem to want to tell me more than that (typical dealership scheme). He said the part is $300.

Does anyone know exactly what part he's talking about? ECM maybe? A remanufactured ECM is only $126 at O'Reilly. I'd like to do it myself, since he said an hour of labor and that means it's easy, but I don't know what part specifically I need to buy. There is a programmed supercharger profile in the car, flashed by the dealership for the S/C kit. Will I need to get this computer reflashed with the profile? Thanks in advance for any advice!
