So I'm planning on doing an ECU conversion from M3.8.3 to Speeduino or Megasquirt. I have an almost stock A3 with AGU engine.
Does someone have the M3.8.3 ECU connector pinout?
Does the ECU control anything else than the engine? A/C, dashboard etc?
Would prefer to swap the ecu completly but not sure if I have to run it parallel to the stock ECU to keep dash and A/C etc working.
Any tips are welcome, relatively new to 1.8T world
You may be asking why I want to do this? Well I don't have the skills/equipment to map the stock ECU. I'm much more comfortable with Megasquirt and TunerStudio and I will start building a big turbo engine after I get the new ECU working with stock engine.
