How do i do it? I got
a new ecu thats same code and also from a quattro manual but when i installed it and started the car it surged between 600 and 200 rpms almost stalling constantly. I heard this will solve that. Thoughts? How to?

 

You will need a Vag-Com or a 5052 to do a throttle adaption.

 

turn the key to turn the electric on and let it sit you should hear some electric actuators and **** moving under the hood let it sit for 3-5 min that should do it. I'm not sure if its the same level of adaption as vag com but i know that a tb adaption and it works

 

It's not as precise as forcing it with Vagcom but do it 3x with a few minutes between each and it'll get you pretty close. From that point, the ECU will learn the rest on its own with some driving.

 

Cool im gonna take out my ecu tgat came with my car. Send that to giac and put this one and and tb learn and drive it until i get my chipped ecu back.
