Hey guys, I have 1995 Golf MK3 1Z (90hp). I have built fully forged AHU engine to run VNT turbo for around 200hp. Guys I need your help with ECU, my ECU number is 39 89 028 906 021AF. What PnP ecu for VNT should I look for? Btw i'm from europe. Any audi a4 b5 early model (95'-96') ecu fits? Thanks

Any good tuner will just give you a VNT set of chips for your current ecu.



Or if you dont want to go that way


028906021GN
or

028906021CE


or any other 028906021** from a car with AFN engine code. VW/Seat ecu's have slightly different cruise/brake switch wiring than the Audi ones but it's all fixable.

So if i get you right, with Audi ECU 028906021GN or 028906021CE I would not have any broblems with cruise/brake switch wiring? I want to avoid that if it's possible.

You would have problems using Audi ecu in a golf.



Golf AFN ecu's are rarer...


But like I said a good tuner will put a golf afn chip to your golf ahu ecu..

I'm about to kill an AFN ecu to make adapter to 121 pin :/
