Re: APR Chip question.... (MeddlingKids)
I'm pretty sure I explained this to you before, but here we go...
You shouldn't swap just the chips, but complete ECUs. Why desolder both boards and swap in your daughetboard with his stock chip, as that is potentially harmful to the ECu, when you can simply swap the entire ECU? You need to have the same ECU code and both will have to re-intialize the board after installing. To do so you need VAG-COM.
