2001 audi tt 225 amu 6spd 1.8t amu engine
Matching ecus are too pricey for me.
But the junkyard has tons of Mk4 vw or b5 audi ecus for dirt cheap.

I have bin files from my audi tt that I can flash over whatever ECU I buy.  But I don't know what cars to avoid.
I know I need a narrowband car.
But do I need to match auto/manual??
Also are there any years that have no immo?

There's also weird things like vvt or egt my car has none.


I guess the main question is this:
With a reflash fix all inconsistencies (outside of narrowband/wideband). Or do I need a very specific ecu
