trough developer mode of my STAR machine i enter in menu coding>SCN Kodierung PKW
And there was a drop menu with a lots of codes. My original code was AH04
Disconect myne and conect the TCU that i take from a diesel model, open the same menu and check the code - AQ08
So i chose from the drop menu AH04, and the car drives like it should be, no limp mode, no out of sequence gear changes!
I want to ask specialists, is this the "coding" of the TCU that needs to be performed in order to get the C55 TCU working in my C32 ?
Or there is other more complicated things?
There was other menues with codes and some other things on German, but i did not massed with htem. Here are a pictures, maybe someone can help with info?
This is where i chose AH04 like was on my original TCU
The rest of the photos are of coding options which i don't know what to do..
Here you can chose from the drop menus if the car is code 030 AMG, if it's European etc, if it got paddle shifter and more
the scn code u change is for differential ratio, u set the other tcu to take the same diff ratio and it took it cause the car it came from has the same can bus, but u can't change other options like shift rpm or manual mode, those options are in the software/flash.

Hi Robert,
And the C55 TCU will not run in C32 because it's different can bus?
atleast the diff is the same ratio
P.S. do you know a P# of the CLK55 2003 TCU that will work on C32
Regards

Chicho,
I read the entire thread but i found only one guy that got M mode from performance center in affalterbach. Will send him a PM to ask about the details and pricing.
few days ago i found your thread about C55 TCU in your CLK
What obstacles did you meet?
Greetings
No obstacles at all . Just plug and Play ...
Biggest difference is TCU of CLK55 03-04 , paddles works only in M mode , while in CLK55 05-06 & C55 05-06 paddles works on C,S,M + Holding gears on M mode.... I did this update cuz my car is 04 . So It was an easy upgrade in few minutes....
What was your previous code, AH04 is the same for every C32?
I saw atleast 200-300 different codes (it took a lot of scroling), i said to myself - there is no chanse for so much diff ratios in cars with EGS52...
What is the performance of the EC unit now? Little bit more revs to shift, at least 1800?

Previus was maybe AH50 or something, dont know why..
Before = about 50km/h it change 5th gear (feel one gear too big)
Now = 4th gear driving in same speed, and maybe it change lower gear more easily (more responsive)
Thats sounds good, something simillar to the stock TCU, and if the advantages of the manual, raised torque limiters and fast shiftings are still there, this will be nice to have in C32
I installed for testing a CLK55 03 TCU but the shift points was very low, at 1500 rpm.. Need to put it again and chec the code to see if it's different from AH04

That TCU have M-mode? Yes check what code there is.
Its too bad you cant upload that CLK55 TCU file to me, you need special tools to read it out. I have the tools to compare programs.

Is that "holding gear" true, so revs goes to limiter(and holds) and no shift? Or is it shifting when it goes to shiftpoint?

Yes, in the C55's M-transmission mode, the car will not upshift even if you hit the rev limiter. It will, however, downshift on its own to prevent stalling if the engine is at very low rpm's.

Great, that i want! This EC M-mode is useless becouse it not hold gears.
