VAG ME7.5 build

[deaner]

Hey all! Just here creating a thread to document process of getting my 2000 Audi A4 1.8t setup on Proteus. Parts are ordered and hopefully enroute so I can hit the ground running when they show up. Currently the car is big(ish) turbo, all the bolt ons and running standalone from Ignitron ECU and is tuned by me. An ECU I absolutely adore mind you... just wanting to play with some open source stuff and I love tuner studio! With this car I've open sourced tuned the factory ecu, then had Eurodyne Maestro for bit and now I've been using IECU for almost 2 years. The cars been a daily for a few years now and after picking up a 2008 Audi A3 3.2 last spring to replace it, the A4 has officially been moved to track car/test mule status!

Plan of action once all parts have arrived, is to build a PNP harness using RusEFI breakout setup. Then just get the car to run. I'm comparing wiring schematics currently and I dont believe I'll have much issue wiring it up. I'm more concerned with my lack soldering skills! Lots to learn! I'll update as parts show up and I'll try and get some picture rolling too. Looking forward to this project!

Sweet-sweet, we can use your help if/when we go with a PnP 121 pin ECU!

I've create a stub of https://github.com/rusefi/rusefi/wiki/VAG-B5 page and linked on https://github.com/rusefi/rusefi/wiki/Vault-Of-Vag-Info

If you would be interested to document stuff that would help us like for instance https://github.com/rusefi/rusefi/wiki/HOWTO-M73-v12-on-Proteus https://github.com/rusefi/rusefi/wiki/HOWTO-M111-on-microRusEFI

Absolutely! Projects just waiting on parts at this stage. I've started putting together a spreadsheet for pinouts using the RusEFI 121p breakout board. Thanks for the diagram on the wiki page btw! Helps some with colors and such. Between that and the pinout schematic available for the standalone that's in the car now, it should be pretty straight forward. I'm planning to add a couple wires in my jumper harness for future compatibility in my A3 too. Will make hotswapping ecus easy for development on the newer chassis too. Theres not a whole lot different in the pinouts between the two cars. I plan to info dump here as I make more progress. Should be fun!

Oh, figured I'd just ask as I havent gotten the answer via searching/reading that I'm looking for. Proteus does in fact have onboard WBO2 yeah? I can feed and configure the factory 4.2 lambda sensor that's in the car now?

http://rusefi.com/ has a link to https://github.com/rusefi/rusefi/wiki/Proteus-Manual now

no WBO on Proteus at this point

Yeah, I've been through the links a couple of times and must have missed a definitive answer in there. Bummer no onboard WB, oh well!
