TunerPro - TunerPro is freeware and there are a lot of community provided definitions (XDF files). For MS45.1 take a look over in our Definition Files. BimTun - Somewhat affordable and does not require a map pack, the maps are built-in, but the number of maps available are limited. Offers support for changing some of the more popular settings.

Not quite bin files are the actual program (and sets of variables) that you upload/download from the ECM. The drop down ECM menu in tunercat selects what you'd call a 'definition' file. That tells tunercat or tunerpro what parameters are in the bin, where they are located, how to convert all the math, how they're organized, etc.

Second generation Split Second programmable products are designed to use TunerPro RT software.

TunerPro RT is a very flexible and powerful user interface for engine tuning. It uses three types of files to operate, xdf (definition files) bin (binary data files) and adx (data acquisition files). Xdf files define the parameters that can be adjusted and their memory locations. Bin files store the data that is used to tune the engine. Adx files specify the real-time data and dashboard functions.

The software can be downloaded for free at http://www.tunerpro.net. Be sure to select TunerPro RT. The non-RT version does not support real-time data. We strongly recommend that you register and make the requested donation to support future enhancements to TunerPro RT. There is a wealth of information about how to use TunerPro on their site and in the Help section of the program.

Split Second supplies the xdf, starting bin and adx files which can be found in the Downloads section of this site. Engine tuning is accomplished by modifying the data stored in the bin. Multiple bin files may be created and stored that represent different states of tune.

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.
