ok, I'm just currious and had a dumb question..
I just bought a virgin p28 and a harness. what will happen if I connect that to my stock y8 engine?

 

if you got the conversion harness and stock p28...it will make the car run like crap. The p28 and p2p have totally differnet mappings...

edit: You would only benefit if you got the ecu tuned and mapped to run with your current motor.

 

cool, gotcha.. my main thought was just connecting it to test the ecu to make sure it worked
