Hello, I have a Audi 90 Quattro with a 3B engine.

This is a 5cyl 20valve turbo.

I am planing to remov the ECU and install this VEMS to tune the engine.

The engine has 2 knock sensors that should be used and a idle motor.

I don't have: boost controll

I planed to take out ca 500hp of the engine.

Anyone done this engine before?

All tips are welcome!!!!
