This thread might be a good excuse to put together a "Getting Started" list of things for new people. Here's something I wrong up quick.
1) Reading your car's stock file from the ECU
- Tony's free
Nefmoto Flashing Software is the easiest and best supported method. You will need a cheap
flashing cable.
- If someone goes wrong you will want to have a Galletto 1260 cable to hopefully rescue the ECU in boot mode (a lower level protocol)
2) Editing your tune. Here's what you need:
- Tunerpro is a free map editor. WinOLS is a more expensive map editor. Most people use TunerPro.
- TunerPro will need a definition file (.XDF) for the ECU file you want to edit. This tells TunerPro where the various maps and relevant data are in the file. There are several XDFs posted on this forum. Many are works in progress, if you find an error please let the author know.
- Knowledge of which maps perform what tasks and what data should be changed
3) Correcting checksum values in the tuned file
- The tuned file has several internal checksums that need to be updated when the file is altered. If these checksums are incorrect the car will not start.
- mtx-electronics sells an affordable TunerPro plugin that will correct checksums for ME7:

- Nefmoto flashing software
5) Logging the car's performance
- Vag-Com
- APR's ECUx. Not really supported anymore.
- We're hoping for more logging options in the near future.
6) Your contributions.
- The open source VW/Audi ECU community is evolving nicely. Please help give back by providing your feedback and helping others.
Finally, here are some valuable tuning resources
-
http://s4wiki.com/wiki/Tuning is an incredible ME7 resource put together mostly by nyet. Check out the other articles on the site.
- Bosch ME7 documentation:
