Caterpillar XXXXX.fls flash file writing

[FritzP]

I will try to shed some lights to this thread. I have been tuning Perkins engines for some years, and Perkins use the same ECM as Caterpillar.
Forget all this about Master ET and flashfile editor. What you need to do are reading out the binary file from your ECM, then edit this file and write it back to the ECM. For reading and writing/programming you will have to use a BDM tool, because this ECM's have a Motorola MPC5XX processor. There are several suppliers of BDM (background debugging module), I personally use BDM100 made by EVC. For reading and programming you will have to open up the ECM. The file you are reading have to be edited by WinOLS. This is a licensed program made by EVC. There are some crack out, but beeing a pro tuner I work with licensed software. You will also need a plug-in to handle the checksum for WinOLS. The BDM100 will read the whole content of the ECM, and not only a partial read. With this feature you can also make a clone of an ECM, or even virginise. There are now lately launched tools from other manufacturer that can flash bin files directly to the ECM without the need for opening, this is the KessV2 made by Alientech. This is very handy when you already have the file readout and just want to make a quick correction, and you can then do so directly through the diagnostic connector. With these tools you can edit and release the hidden power of your Cat or Perkins engine. Editing the files are the real job, and require a lot of experience and testing. Good luck.

New Genius also supports writing bin but kess/genius cannot read. You still need an ori reading for that software version, make mods and then write. BDM100 is a nice tool.. I use Trasdata as well.
