Zayed,

Thankyou! that is one very rare car!

Unfortunaley I dont think I will be able to make mine tiptronic as the shifter mounts to a totally different trans tunnel on the tiptronic models, maybe I will be able to make it work with normal gate shifter who knows?...

Regards,
Paul

Yes sure, keep your gate shifter, & swap the Engine only, it will works great....

Zayed,

I want to swap the engine,636 trans,prop shaft, axles and drive flanges...so final drive will be 2.82, so I assume it will need the clk55 TCU,ECU,ESP etc?

On the clk55 ETC wiring diagrams terminals ~20 -28 are labeled "not used" as gear slection is sent over CAN....on the C43 these are used for the anolog gear input from the gate shifter.
Unlikely but I wonder if the CLK ETC will accept anolog on those inputs?..

mechanical selection of P-N-R-D must be same on both 722.631 and 722.636?.

cm60k

No need to change proper shaft/axles/flanges,

722.631 & 636 are the same with an out-put power, which is 580NA, no need to swap them,,

if you change the 2.82 diff., the gear shift will not work at all, and you will force a big problem with ECU/TCU calibration....

ZAYED,,

Pagz

yes but prop,diff axles and drive flanges are the uprated parts used in C55, I figure why not use them if I have them?.

Also, I want to use CLk55 ECU, TCU and EIS ESP so that engine and drivesystem is compatable. only problem is tiptronic shifter...maybe I keep reglular gate shifter but remove tiptronic module from the tipronic shifter and mount elsewhere in the car,add paddle shifter on steering wheel with radio comms like Fabian.

Zayed, is your friends C55 a jap-import or did MB officially import this car to Middle East?
did you compare this c55 to your car?
which one is faster and runs better?

your c55 with kleeman stuff is it a genuine c55 or did you swap engines?
do you have the 280 or 300 speedo in your car?

cm60k

What’s the advantage with the CLK55 shaft/axles/flanges...?,

if you want to go with CLK55 shaft, you will need to replace the rear flange(which is 4 legs vs 3 legs),

is axles thicker than C43 axles...?,

its not necessary to go with all that, but depend of your choice,,

CLK55 ECU has the an ESM/DAS controller authorization for tiptronic & fire-up, not sure how it will work ...!!

Dennis,

my friends C55 is special order for gulf spec., my friend is a second owner,,

my car is originally C43, but i swapped the Engine to 5.4l,

my car is faster than my friends, cause i have Kleemann Headers & Cams, and kept the 3.07 end,

but my friends C55 is bone stock with 2.82(which is a little bit slower than 3.07 from a dig start),,

honestly; when i drove my friends C55, i felt soo soo pleased, its definitely better than mine....

ZAYED,,

Pagz

Zayed,

Yes Prop is 4 finger but remember I want to use entire CLK55 drive train, axles are thicker,wheel flange is different too but uses all 202 parts.

As far as I know these are all parts used on C55, check your friends C55 axles!?.

Why would Mercedes bother changing all these on C55 if not needed

Also, does 2.82 not suit the extra torque of 5.4?

oki doki, thanks Zayed

AMG used CLK55 diff./axles/flanges to match the bigger housing of 2.82 diff.,

the reason with swap the diff. to 2.82 to reach more than 290km in autobahn,

*i think the only way to make 2.82 works with your 631 gear & gate shifter,

that needs to put the TCU from "98-99 W210 E430/E55",

im using my car with stock diff./axles/flanges since almost "5" years, without any issue,

i switched the diff. to LSD with smaller housing from 300E 4matic,,

(even smaller than stock C43 diff. housing 4 month ago with [0] problem....

ZAYED,,

Thanks Zayed,

Hmm.. is final ratio stored only in TCU, or ECM as well?

Is yours much faster with 3.06?

After i ran 380Hp through the 5 speed manual with 3.46 129 Diff, you could feel the whole rear end diff/subframe/suspension move at full torque,it felt like the car steps to one side but there is no loss of traction, the gearbox showed heavy signs of wear after less than 5000km's. although swapping from 4.3 to 5.4 is not a large difference like going 190 to 380hp i am now cautious as to why they run larger parts.

I'm interested in why they run 4 finger prop shaft instead of 3?

also,I have a hidden motive to run the 2.82..one day I want to run a bespoke NSG510 6-speed , the rear diff on this is down around ~2.62 for this, I thought the 2.82 would be more suitable than 3.06.

Regards,
Paul

Diffratio is stored in the TCU only, not in the ECU. I swaped from 2.82 to 2.65 to run tests with the W211 E55 TCU before i let renntech recode the TCU to 2.82 Axle. After anything worked out fine i swaped the Diff again and send the TCU over to renntech.

as my car runs nearly 290km/h without supercharger and new headers 3.06 where to much i think. I think 2.82 is fine for a 5.4L Engine.

Also the 3.06 is the "small" Diff with the small body and the small gear-wheels. My Parents own a '00 W210 E55 4matic Stationwagon which was originaly transfered from a E430 as there is no W210 E55 4matic Station from stock ... only manufactured on customers wish by AMG (or other tuners like the car from my parents is manufactured from Kicherer)

AMG used the 3.06 Diff, 3-arm-shaft and the Original Transmission but combined with a special TCU Software. The TCU in my parents car has a unique AMG "HWA" Partnumber.

the car now has 330.000km on the clock, bought with 320.000 ... the Diff mounts and the shaft flex disc where only partial present... i changed all of them, both flexdiscs and all 3 diff mounts.

Ok 320.000 is much ... but it is a lot of power ... if you could stick to 2.82 and a 4-arm shaft, DO IT!

Also i am not shure the transmissions are the same... i hear a lot that the 632 and 636 only hat the 3-arm or 4-arm connector ... but after a little research the 636 has 6 clutch discs and the 632 only has 5!

Any time Paul,

The diff. ratio stored in the TCU, but TCU send authorization signal to the ECU for fire-up, through the DAS system,

i have a stock 3.07, which has smaller housing than 2.82,

3.06 has the same 2.82 gearing & housing size,

as i know; MB put 4 legs as optional for bigger flex disc, to handle a more out-put power & more survival,

changing a diff. ratio is easy for a tiptronic cars, like Fabians,,

but with a gate shifter is soo hard, unless if you make a stand/alone TCU system.....

Hi Zayed,

Sorry I made it confusing...I ment 3.07(C43)not 3.06 , I did not realise there was A220 diff with 3.06,which models have this?.

As I know:

3.46 - A124 Case,A124 carrier, 165mm crown. manual 202, 201 etc
3.07 - A210 Case, A202 Carrier, 185mm crown. C43,other 202/210/208
2.82 - A220 Case,A220 Carrier, 210mm crown. clk55/e55 etc

I think the best way around all problems is to run entire CLK55 electronics.

What makes changing the diff ratio easy with newer TCU? how to tell if you have the right TCU?

Thanks,
Paul

Pagz

Fabian,

thanks for the info.

When recoding is done, is this bespoke software or can this option be done through SDS developer?

So the 722.636 is definitly same output ratio as 631 or 632?

Regards,
Paul

cm60k

I think also W124 uses 185mm, not 165mm, not so sure about that,,

you will need a lot of job if you want to swap all CLK55 electronics,

with a newer TCU, do you mean EGS51 or 52...?, if EGS51, should be taken from E430/E55 with 2.82, if EGS52,

you can reprograme it with any diff. ratio you need,,

that depends to your progress with changing the whole CLK55 ECU/ESM/TCU, with tiptronic & all wirings.....

ZAYED,,

cm60k

Yes, i believe all 722.631 & 632 & 636 sharing the same out-put, i used the stock 631 about "4" years with 5.4l,

still strong with-out any problem....

ZAYED,,

Auto W124 probably uses something like A129 diff maybe?..not sure.

I've compared alot of wiring diagrams between 99 C43 and ME 2.0 CLK55,the diagram and plugs are mostly same but made confusing because they draw same components and wiring but in a different layout between models ...major changes are due to Illumintation module and tiptronic harness. CAN is all same appart from additions for tiptronic. There are minor changes for ESP.

I'm not sure which TCU CLK55 has, maybe EGS51? when did EGS52 start?

I think I will try to change all CLK55 electronic's including tip shifter,but not illumintation module as it definitly will not fit.

Another option is CLk55 looks to use W202 tiptronic trans tunnel, I could swap this also but obviously is alot more work.

Pagz

Guys,

Which modules are locked together in 99 C43?

is it ECM(ECU) - EZS(EIS) - steering lock, or is there more?.

thanks.

kaype

ECU, EZS and the Steeringlock are "one unit" and have to be swapped all together.

EGS52 wont work with ME2.0, if ME2.0 is used you need EGS51.

you cannot change the diff ratio via SD, even not with Dev. Mode. In EGS52 you can code the models but not only the ratio. I needed a W211 E55 EGS52 with diffration 2.82 and not 2.65. This was done by renntech. They modified my original software and flashed the whole TCU with it. I dont think this can be done by using only a SD. Renntechs first atemp was to flash a newer software to my TCU, but then my program switch on the shifter had no function anymore. but i tested it and saw a completly new part number in the SD so renntech changed the complete software of the TCU in the first try.

greetings, Fabian

Pagz

Fabian,

Thankyou for confirming this.

Therefore configurations from 1997 - 2002 must be:

ME2.0 ,EGS51 and gate shifter(98/99 C43 ,CLK430)
ME2.0 ,EGS51 and tiptronic (2000 C43, CLK55)
ME2.8 , EGS52 and tiptronic (2001 ,2002 CLK55)

I would think this would be similar for E55?.

Also, how do you like the paddle shifters on the steering wheel when you are cornering?,do you think having them fixed off the steering colume is a better setup?

Regards,
Paul

kaype

The E55 i used for my engineswap came from England (Right Hand Drive), was build in 03/2001 and had ME2.8 with EGS51!

i think the EGS52 came somewhen late 2001/2002. But maybe a little earlier in the CDI's. My friends W210 E270CDI is also from 2001 but has the EGS52.

I swapped my EGS51 to EGS52 after the engineswap ... but then i allready got the ME2.8 in my car, it worked without any problem. I tried EGS52 on several Cars with ME2.0 or even ME1.0 (E50, E55, E320) non of them fired up.

So my conclusion is:

ME2.0 needs EGS51
ME2.8 can run both, EGS51 AND EGS52.
