Hey guys, I am going to be taking my 2003 Grand Am GT which has a 3400 V6 and pulling it in favor of a 'mildly built' 2.2L Ecotec which came out of a wrecked 2003 Grand Am base model.

Now these are obviously the same car(albeit with a different motor but same tranny) but is there any reason that I can't just swap the engine and PCM and be done with it? Would the wiring/harnesses be different or should it just be plug and play?

Also, I will be needing VCM Suite to do some tuning on her. I know that both 4cyl and 6 cyl 03' Grand Ams are supported BUT won't my VIN show that I have a 6cyl and not a 4cyl?

Anyway even though it is a VERY easy swap, my only concern is about the VCM and issues it may have..and with tuning a specific vin.


Thanks in advance
