Hi so i have a 2.2 ecotec 2004 z24 cav and i picked up a supercharger kit off a cobalt (m62). i pretty much have all the parts to make the conversion. already have the full exhaust put in and all but it needs a tuned. In my area theirs not really anyone that can tune correctly so my question is. can i pull the ecu and pcm off a cobalt ss. would i need both the ecu and pcm to be flash already or just the pcm. and would i have to grab it off a 2.0 cobalt or the 2.4. im assuming the 2.0 if anything?

Cobalts use completely different ECUs/PCMs and will not work with a J-body.

Are you located in Canada?

Having a 2000+ LD9 ECU flashed to the GMPP program and doing a harness swap is really the best solution for tuning a S/C cav at the moment since the GMPP program uses more conventional tables that tuning shops will be much more comfortable with. Alternatively, you can do what myself and other members have done and buy some books on EFI, tuning, and forced induction, do some research, then pick up a copy of HP Tuners and do some learning.
