I just wondered if anyone else has wired up the AGU for a standalone. Just a little project for something to do.
I've got a J220 T80 connector on its way from the states which I plan to make a plug and play with EMS-Pro. As far as I can tell the only hardware change needed is a 2 wire bosch Idle valve as the stock one uses a stepper motor in the throttle body and this isn't supported by the simple EMS-Pro. I was going to use microsquirt but the inbuilt MAP sensor and boost control on the EMS-Pro swung it.
Ultimately going to swap the ECU over to an AEB powered A4 TQS, uses the same connector but will need a few wires re-pinning.
For those that have done this how far off am I, I'm sure I'm missing a few grounds.
Relevant AGU ECU pins I think I've identified.
