Siemens EGS52 Tune

Hey guys,

I need your help!

Is here someone who has experience with the EGS52 of MB 722.6 gearbox?

I read with Ktag, now I need someone who can tune this TCU for faster shifting and better working Lock-Up-Clutch.
Don't want a free file - I want a good working file, and good working files cost money.

I attach the files: is complete
xxx.FLS is flash
xxx.EPR is eeprom

Thank you guys,

I have a tuned EGS52 722.6 TCU.

If you tell me how to use KESS/KTAG to read the TCU, I will send you the file?

I think it is just 3 lines? 12V/GND/K-line?

what is the Protocol?
