OSE 12P would cost you about 50$ total to get a running motor with. I'm using this for a 4.0l Aurora motor.
I paid 20$ for a 88 trans am ECU, the stock fiero wiring works, and the system is compatible with the northstar coilpacks.

The most important detail is what kind of triggering does the ECM require?
If it's like all the other OBDI GM ECM's, then it needs 1x per ignition event triggering... Getting that from the Audi engine will need custom work.

While it works with the Northstar coil packs, the Northstar coil packs only work with the Northstar trigger wheel (AFAIK).

If the Audi has the 60-2 trigger wheel, and fixed cam timing, then you could run it with the Motronic 3.3 DME from a 1993-1995 BMW 540i... it would have to be tuned, but I believe that service is available from http://www.millerperformancecars.com/

Is that computer the 404DME? If so tunerpro has a definition available for the 540i, and looking at the chip, one can be burned easily with a EPROM burner. Ive done it successfully with a 173DME for a 89 325e/i hybrid. that would work better than attempting a mail-order tune on a irregular engine hybrid.

Any MAF 3rd gen V8 computer will work, or a 90-91 2.5L s-series truck. the fiero connectors for the ECU plug in, but wiring is different.
A nothertar style rigger wheel is needed, and people make them for sale.

Will's suggestion would work better as it's less work. And you could tune it yourself if your willing to learn how.
