Yeah it was a b4 Audi Coupe with the 2.0 16v (ACE engine code). It wasn't the engine itself that was the problem, more that the management was only used on the ACE and 9a (Corrado 16v), and the Audi 6a.
The ABF came along soon after, was better in every department, so the older 2.0 16v lumps only now really get used to bump a KR up to 2.0, keeping the better KR head and cams and older (but more familiar) k-jetronic rather than the oddball ke-motronic that was around for a couple of years before the digifant ABF.
