I hope it turns out well. You have done some very nice work.

How hard is it to tune the VW ECM?
bmwguru MAR 23, 12:00 PM
I just got everything set up to do the wiring and ECM work today. I just had a bottle of the "Nectar of the Gods" to get me going....aka Mountain Dew for you non believers. I have 39 pages of wiring diagrams to go through and shorten/remove/reroute the wiring.
I don't think it is too hard to modify the VW programming, but then again I do this everyday for a living. Some people think carpentry is easy....If I build a box out of wood, it will not be square and fall apart as soon as it is moved.

Looking great! You're really making me think about a BMW V8 in my 84 Fiero.

I spent the last five hours making one of the engine harnesses. I took the connector apart at the computer and removed the wiring by the pins for a cleaner look. Right now, it is not in a loom, but I want to lay it on the engine and see where it needs to be extended and shortened. Incorporating it to work with the GM electronics shouldn't be too difficult. The hardest part was going through the 39 pages of diagrams and figuring out where each wire goes into another module. Then removing the body module from the circuit and completing the wiring back to the ECM. This is a CAN car, so the modules all talk to each other.
So, in a few hours I should be able to have the wiring loomed and installed. Tomorrow or Tuesday the battery will be installed and the last harness for the starting and charging system will be added. I am keeping the wiring as close to VW stock as possible to make it easier to diagnose when something goes wrong.
We just may have it ready for Joey when she gets back.

Who is "WE"?!?!?

It's great that you're hoping to have it done for when I get back, do you really think it will be? Thats an awful lot of wiring to go through. I would have liked to have been there to help you with that.... but I probably would've been in your way... or messing sh*t up.
