Hi ladies and gents!
As some may know, I've swapped in a 4.2 V8 40V from a 2005 D3 A8 (BFM) into my 2000 B5 2.8 Quattro Sport 5-speed manual.
I used an ECU from a 2001 D2 S8 (ME7.1.1), in conjunction with a hybrid wiring harness, combined of the stock D3 and an S6 C5 item. My car is running, but with tons of codes. Running quite rich too.
Going through the wiring diagrams of the C5 S6, and checking pins in the connectors, as well as the connectors of every engine connection, highlighted discrepancies. Yep, ME7.1. versus ME7.1.1. My harness is off a 1999 S6, very different to a 2000-2001.
I have both wiring diagrams, so I have removed the harness to re-pin it to match the later ECU.
For the benefit of anyone who may wish to do a 40V swap, I have taken the time to put the ECU pin outs in order. So the pins---component / connection---colours. I have just completed the write-up for the ME7.1 which I will post here. I will complete that of the ME7.1.1 later in the week, and I'll add it to this thread. It can then be referred to, hopefully it can be stickied.
