I'm going to be picking up a second hand ECU sometime next week (outta another polo gti ofc), because its the only other thing that I can think off thats giving me the loss-of-power issue at the initial startup of the car. Now, what exactly do I need to do to pair up the ECU to the car. I take it polo gti's are Immo 2, so going by ross-tech:
Install the new ECU in the car
[Select]
[17 - Instruments]
[Adaptation - 10]
Leave channel at "00"
[Read]
[Save]
[Done, Go Back]
[Close Controller, Go Back - 06]
[Exit]
Turn ignition OFF for 15 seconds. Start vehicle.
