i was just wondering if i were to get a second ecu and tune that one if something would happen and i switch back to the stock one if the dealer ship would be able o tell....also if any one could give me a price on ECU's thanks

 

I have one I have never used Brand New. Was going to use it but found ou the here in Hawaii the Tech are retatedand don't know how to do the re-learn. I can send you pic's if you like.

 

Depends. In theory, no they cant tell. But lets say you blow your **** bigger than Peter North on your secondary ECU, and you if you change back to the original ECU, the problem will not show, which = your fcked. Just take care of your car with the second ECU, and you should have no worries.

 

did you try it without the relearn? a lot of people got them to work with no relearn
