NefMoto

Hi Lads.

Im new here on the forum. I have no idea so far about remaping cars and would like to get some informations about it. What kind of software is needed, what equipment/tools? For the beggining i want to try with my 1.8T Audi :) at least i will break my own car :P i have some experience with VAG cars and software so hope this will help mi on the begining. All informations are very welcome :)

Cheers
Jack

Nefmoto s/w can safely flash your ECU using cheap KKL cable - check the sticky s/w thread for all the info.

Once you read out your own ECU, you can determine the ECU model and the software version from the file. From there you can find out where all your maps are with the right map pack (either for Winols, TunerPro etc.)

Then you need to learn what to change and what not to change...

Then the evenings sat in the car with a laptop, and your inevitable marriage breakdown start.

Thanks very much :D is that software: Winols, TunerPro etc. easy to get - is it freeware?

TunerPro is free and well adopted here. Your best bet is to spend a few days trawling through the archives, there are lots of answers there already :)

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 (http://www.nefariousmotorsports.com/forum/index.php/topic,413.0title,.html) is the easiest and best supported method. You will need a cheap flashing cable (http://www.nefariousmotorsports.com/wiki/index.php/NefMoto_ECU_Flashing_Software#Supported_cables).
- 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: http://www.mtx-electronics.com/automotive/page.php?25
- More info about checksums: http://www.andywhittaker.com/en-us/ecu/boschmotronicme71.aspx

4) Writing your tuned file back to the ECU
- 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: http://www.nefariousmotorsports.com/forum/index.php/topic,400.0title,.html
- Some good books: http://www.nefariousmotorsports.com/forum/index.php/topic,455.0title,.html

What else should be included?

Wow great answers. So glad i found this thread. Coming from the dsm world this platform is drastically different haha. I hope this is sticky'd. If not its got my vote  ;D

Everything is perfect untill you need definition file for ECU :/ especialy in my case with VW Polo 6N2 GTI :P

Try to create your own xdf. I help all new members with addresses and locations if they put forth the effort!
