'87 COUPE GT CIS-EIII Wiring Schematic?

7/87 production date. 2.3 5 cyl. CIS-EIII. The Bentley '84-'87 Coupe GT manual does not show this car with CIS-EIII System. The manual shows all with 25 pin ECM. This car has 35 pin ECM. The '88-'90 Audi 80/90 Bentley manual shows CIS-EIII for 5 cyl., but the pin-outs and wire colors don't match. The '87 Audi 5000 Bentley manual-same problem. A call to the local Audi dealer Service-dead end. No supplemental service manuals for '87 Coupe GT w/ CIS-EIII. The car has serious drivability issues related to engine management, but without correct schematic diagnosis will be very difficult. Any Ideas? JR

I would suspect that the driveability issues you are experiencing are due to issues other than the ECU. They tend to be rock solid in the T44s. It is much more likely that you have problems with vacuum, temp sensors, fueling ...

JR, That sounds like one of those Special Build 1987.5 Coupes with the higher compression (NF?) engine, 4 wheel disc brakes and body coloured rear spoiler. The change over the 1986-era coupe in engine management was the addition of knock-sensing. You may be able to find help at Huw Powell's site:

you don't mention the "drivability issues", but you wouldn't be missing the "spare 10A fuse" in the fusebox that is actually needed (but not well labelled), would you?A posting to

I would be suspecting a bad hall sensor in the distributor. They can be intermittent like you describe.
