Tunerpro Definition Files

TunerPro User Forum. Advanced Automotive Tuning Software. Skip to content. i need files, PLEASE!!!! by Stan95 » Thu Sep 20, 2018 3:36 pm. 0 Replies 4065 Views. Tunerpro has improved a lot as a tuning option for the LT1 since i ground away like a hundred hours enhancing the definition file you need tunercat or winflash regardless, and tunerpro is free, so actually you kinda need both of them. And you can use whichever is easiest for the task at hand. The other definition files did not seem to allow any useful chatter to be seen. I logged some data with Carbytes V2 using the HoldenVSV8.ald definition file (the LotusCarlton one did not seem to provide any data). The first part of the log file from Carbytes V2 looks like this: 15:40:08.804,66,98,0,0,0,0,90,128,0,0,118,0,135,7, 16,110.

To read your car's stock file from the ECU you can use Tony's free NefMoto ECU Flashing Software. It is the easiest and best supported method. You will need a cheap flashing cable.
If you already have an aftermarket tune from a commercial tuner, it is likley that they will have disabled the ability to read using this method.
In this case or if something goes wrong and you can no longer connect using NefMoto, you will need to have a Galletto 1260 Flashing Cable to hopefully rescue the ECU in boot mode (a lower level protocol).
To change your ECU tune will require map editing software. Tunerpro is a free map editor. WinOLS is a more expensive map editor. Most non-professionals 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.
Your ECU 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. Or worse, it may start once or twice and catch the invalid checksum and leave you stranded. A lot of guys carry around a spare known working ECU as insurance.
More info about checksums: Andy Whittaker's site.
MTX-electronics sells an affordable TunerPro plugin that will correct checksums for ME7.
Writing/flashing your tuned file back to the ECU is the same as the reading process above. Again, use the NefMoto ECU Flashing Software.
