I want to order a spare ECU so if I ever need to take the car into the dealer, I can just swap the ecus real quick from the chipped one and not chipped. But does anyone know what I need to find out before getting the ecu and about how much? I know some car manufactures have different ecus for different models of cars or 1/4 of the year cars. I just want to make sure I get the correct one for my car.
Also, what is the best performance chip out that will give me the most power with the best reliability. I plan on making the car fast as hell as well. I have heard alot about APR, but not sure about the others. APR is more expensive but you pay for the best quality I am sure.
Thanks guys!

Take out your stock ECU end copy down the numbers on the Lable .That should be all the info off the ECU you will need.Keep in mind you will need a VAG tool to ADAPT tyhe new ECU to your car every time you swap back and fourth.Keep an eye on the classifieds i have seen ECUs on there for 300$ and less.

Why do you need a VAG tool? You can't just swap the ecu's?
