Hello guys, apparently the US tuners aro not dealing whel with the TCU tune for our cars (at least my internet digging found that)
So i wonder if it's possible to change the C32 TCU with one of C55...?
in order to enjoy the manual gear shift, and maybe the infamous 1500rpm jerk will be gone...
Does anybody tryed this ?
Yes both cars are EGS52 so i was also thinking that it should work.
What do you mean by programing it?
I need to do initial start up trough STAR?
Or there is some more complex programing with developer mode?
And the last and most important question - wil it have Manual like C55 or the shifter should be also from C55
My understanding that at least in the early days of the tuned TCUs fro C32 from EC, the software was just copied from another AMG model. The software itself was not mofified. Again, only talking about EC and only talking about the early days.

Anytime mate,
it should be programmed & calibrate with your ECU, this need to be done through special DAS tool,,
tuners can do it, such as "EC/speed driven/OE tuning/Renntech..
Lenin, i was also thinking that this is was the begining
Zayed, what special tool in DAS? I do have a STAR/DAS machine and use it to make some rettrofittings in my car, but the developer mode is unknown teritory for me...
I was thinking that if the diff ratio is the same you only need to connect it and reset all the adaptations.
Or do a new initial start up and maybe wright the car's VIN.
But this special programming and calibration is no go for me
It looks too much for my knowledge...
Sad but i will leave the idea for now :/
The C55 TCU is allready a lot of money, and if i can't make it work with my car.. It will be a true wast of money
Beter option is to get eurocharged TCU tune, but a lot of drawbacks in that software.... Many complanes of members here
My STAR machine is unlocked and it can program offline, i can take codes from a program also offline.
Maybe i will try with some cheap EGS52 if i manage to code it to my car, i will buy C55 TCU
It looks too much for my knowledge...

Don't worry that much bro., C32/C55 got the same diff. ratio with EGS52,
TCU will definitely work, but can't assure that,,
unless you have to try to adapted it with DAS/SDS, or tuners can do it with there DAS/AKA tools...
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?

ZAYED,,
Zayed,
Will search for acheap EGS52 so i can test my abilities to work with DAS.
If manage to get it work, will take the next step - buying a C55 TCU and get it done in a C32
Correct me if i'm wrong but i will need the same P# TCU like mine, or the interchangeable numbers acording to EPC?
Here are the TCU's that fit my car acording to EPC, the first is my actual.
I found few like mine cheap in germany only the shipping will take some time. because i'm in Bulgaria (1200 miles from Germany)
The listing say that they are from diesels... wich are with 2.65 diff but the part number is like mine I `uess that the seller did some mistake
And last question: what rpm is the C55 rev limitter?

Anyone interested in an C32 TCU tuned by EC , used for about 1 year. Car will revert back to orginal TCU so i will sell it now or later depending on offer.
Send me a PM if interested.
guys the clk55 tcu 2003 work in our c32
the clk55/c55 2005 tcu won't work in our c32, it needs coding,
but all of those cars shift between 6500/6700 rpm and our c32 shift at 6200, so if u install those tcu's in a c32 u will hit rev limiter each gear.
Now i'm thinking that maybe the EC tune for C32 is really C55 based
Because many members sayd that their cars behave like this:
- Changes too early to a bigger gear on daily drive
- Requires almost a kickdown if you want to change down
This is more suitable for V8 because the more low end torque
Maybe some C55 owners will say how the original TCU behaves?
It is simillar to this?
And if original C55 TCU is used in C32 i think the shift points will be higher and there is need of ECU tune
On what rpm are the gear changes on a stock C55?
I went from the C32 to the CLK55. They feel like they have very similar torque curves and the stock TCU behaves in a very similar manner. It certainly doesn't change gear really low down in the rev range.
It is adaptive as I believe it is in most AMG's. I taught mine terrible habits, sometimes it sits at 3000-4000rpm thinking I might floor it again (since I often do). TCU reset gets rid of it until it learns again from me. It changes down to one gear lower with moderate throttle input, certainly it doesn't require a foot to the floor. If I drive like a normal person it will eventually revert to shifting at 1800-2000rpm with light throttle.
The C55 might be different to the CLK55 as it came out later, not sure.
tw2, this is great news!
So the way to go is C/CLK55 TCU just to find out how to make it work!
There will not be problems with the slow city driving like with the EC TCU tune!
Hi Robert,
And if you give us the correct P# for the CLK55 03 TCU you will be priceless!
Because acording to EPC there a few P#'s
It's a direct swap or you still need to have advanced DAS skils?
How to proceed in case we got one?
Yesterday i take one TCU from a diesel W203 but with P# tat fit's my C32 and today will try to code it to my car.
I know about the higher shift points of the 55 TCU's but this should be no problem if we tune our cars by EC and get the 6500 rev limiter.
What's the shift point of C/CLK 55 TCU 6500 or 6700rpm?
