thank my friend ,it was changed 260 to 320 ? , i have another question , it's my first double ECU for read , FGtech give me automatically 2 files one XXXXX.oriM and one XXXXX.oriS , i think one master and one slave , but for write with FGtech i need rename the 2 files in XXXXX.modM and XXXXX.modS , open the XXXXX.modM write and FGtech write after the XXXXX.modS automatically by the name , or FGtech ask me for the second file ?

thanks by advance for your help

M and S are same file obviously!
mod only one file and use this one for write M and S....the differences are in mpc and e2p but flash are the same file.

It's depend what you want achieve, Rise RPM can be danger for engine.
