Reading your car's stock file from the ECU
Tony's free NefMoto ECU 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 Flashing Cable to hopefully rescue the ECU in boot mode (a lower level protocol)
Editing your tune
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 in the Nefmoto Definition File subforum. Many are works in progress, if you find an error please let the author know.
You will need knowledge of which maps perform what tasks and what data should be changed. Read the S4Wiki.org tuning guide and the Nefmoto tuning subforum
Correcting checksums
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.
More info about checksums: Andy Whittker's site
MTX-electronics sells an affordable TunerPro plugin that will correct checksums for ME7
Writing your tuned file back to the ECU
Same as the reading process above: NefMoto ECU Flashing Software
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.
