I'm also interesting this problem. After strong engine ecu remap, there will be very proper making transmission ecu modification. What type of mcu is inside? If mpc or st, counting checksum is probably made the same method, as in engine ecu with the same mcu, mean algorithm is the same...

What tool do you use for read/write?

If you have egs51, this can not be tuned... You should consider changing to egs52. The egs52 can be tuned and ktag make chk on this :)

I use programmer, Have you some files from egs52?

Or somebody have files from amg tcu egs51 or egs52?

Man i think everything with ecu can be tuned :D I think my car is 18 year old and i need know how much can be mercedes good :)

I have linearized 4BAR MAP sensor and this is my first automatic gearbox...

I´m interesed for tuning this ecu...

If somebody have free experience for me (US) you are welcome in this GEARBOX THREAD :chuncky:

Now i need read these ecus :rofl:


606820 AND THIS 606822

For understandyng why are here so small holes--> and if helps when i resize these holes

(quicker shifting or maybe more delivered oil to clutches for increase nm transfer) 606826

Have anyone experience with resise smaltest holes in this plate?

Any luck with the egs51 checksum? After buying a few modules on ebay, I think I narrowed down where the checksums are located. Stuck on the whole calculation part though...
I think the checksums are located at (01108-0110B) and (11108-1110B).

Here are two similar files I used to find (what I think are) the checksums.

Looking like checksums, but how to calculate? Can anyone do it?

Its possible make small aplication to calculate it? Maybe for egs52 too ?
