    Why would you worry about the gear ratio, pretty sure C43, CLK55 ect all had a 2.82, so you can swap the diffs and the ETC or ESP modules won't even know!

    I believe you can code C55 202 software into your stock ME. It wouldn't be any different then CLK55 software.

    Hey Dennis,
    I'm looking forward to the challenge!, I have always wanted the newer ICM and 5.4 engine, the plan is to make a factory look install out of it.

    Yes sure thing, plenty of pics to come

    Remo,
    Pretty sure all C43's are 3.07? ( 202 housing - 185mm crown)

    Yes exactly the reason I want the CLK55 ECM,I'm sure it will be same as C55 tuning seeing as they use possibly the same exhaust,the CLK55 front portion and cats are all 202 C43 parts,the rear muffler looks like a modified C43 one to suit the bumper(just cut and welded down the outer side).
    I have read the C55 uses a different centre muffler, Ironically the CLK55 centre muffler is different part number(#208) to C43, It should fit the 202. I will compare them later this week.

    I've had a look through the ME2.0 ECM on C43 and there is no option to code anything in developer, I think it maybe only possible on ME2.8?....

    You're right. 3.07 it is! Then why would you want the 2.82 ??

    Pretty sure you can change the variant coding. You need to contact Beckman.

    Remo,
    Some say the 2.82 is only needed for top end, however I think MB would not put that in the CLk55 if it adversely effected bottom end to much.

    The main reasons I want to run the 2.82 is because the C55 does and to keep CLk55 modules happy.

    Other thoughts that make me want the 2.82 are the larger 4-finger prop shaft...I can only assume MB runs this for higher torque applications,why bother running it on the M113 5.4 if not matched to the torque of the engine? it also saves me swapping the trans output flange.

    I will check again on the coding. Thanks for the heads up I will contact Beckman and find out what they know on ME2.0

    Cheers

    Yea I am pretty sure you can code the 2.0 ME to 5.4 mapping, leaving all the other modules alone. I would think the 3.07 with a 5.4 would be more peppy then with a 2.82.

    I'm pretty sure the rest of the driveline would handle it- I've only seen 1 incident of a 4-finger driveline snapping in half (113k heavy modded, drag raced)

    I had a better look through the ECM coding ,the initial script says something like " only code new modules" - so it appears you can only change it when the module is new??... there are options like transfer the coding, download and view coding ,use VIN to find coding or enter coding manually from factory data. As I was viewing this on the C43 I did not try to enter the CLK55 VIN and hit enter,hmm though I doubt it would have worked?.

    I did however finally figure out the major differences in the C43/CLK55 exhausts. Only on comparing them side by side does it become evident - the CLK55 centre muffler is identical to C43 externally and internally, however the dogleg part of the pipe steps some 15mm more to allow clearance around the larger Diff, this of course matches in with the Rear muffler.

    The rear muffler is slightly different than I first thought,apart from the obvious cutout to match the CLK bumper and dogleg to clear the diff, Unlike the C43 the exhaust tips are dead straight,the tips are higher up (which match in with my C36 kit much better) and the muffler body is dead straight. The C43 muffler body has a slight angle as you can see in the pics. The CLK55 mufflers fit so the plan is to use this with the conversion.
    The burning question is what does the C55 use? its likely to use the 208.374 centre muffler...but what is the rear? maybe a one off set of ~60 just for the C55?. I'll have to ask the local C55 owner to check the part# next time he's under there.

    Here's a few shots of the 5.4, Really happy with how the internals look ,with extended oil changes this must have been run on synthetics its whole life, my C43 is gold/brown and has much less km's,yuck.

    Are you in SDS simulation mode?

    Ill try to find out for you how to change the coding.

    On my C36 we had a custom code provided by Beckman, but we did NOT have to send out the ME to unlock it. I have not coded a C43 ME to 5.4 spec, though I know several master techs @MB that have including one who was a shop foreman (and was his own car) it's was a simple task

    Hey Paul,

    The first thing, if you want to swap 4.3 with 5.4, the only thing you have to swap is the Engine,

    its NOT possible to change the ratio from 3.07 to 2.82, cause ECU & TCU should to be married with all ratio signals from the speed sensor & RPM,,

    if you want to make your C43 as an original C55, you will need to swap everything,

    (ECU/TCU/all Engine & gear harness/keyless infrared switch/steering lock/gear assembly/driveshaft with flanges),

    which side you want to path with....??

    ZAYED,,

    Remo,
    Good point, I had not been back into simulation since I purchased, The reason I obtained a developer key in the first place was after I noticed how many more options there were in the simulator haha.

    Looking back into it ,for some reason simulator only brings up ME2.8...even when you input my C43 VIN etc it comes back with 202.033 - ME28 It is slightly different menu's/options than I described ME2.0!

    Would your 97 C36 have been ME2.0? Do you know if it was easier to convert to manual seeing as the I6 did come with manual options?

    Was trying to avoid bringing this up as I'm sure its a much larger worm can=),a manual C55 is my ultimate goal.
    The 711.670 NSG510 manual 6 speed trans uses a 2.47 rear end, I was hoping in the long run the 2.82 would be a better suit if I ever change to it, one thought was to build a plug in module that simulated what the TCM wanted to see from the speed sensors ,valves and temp...I'm sure its possible with time haha. Coding out would be the preferred option.

    If you find out any more from your MB guys let me know!.

    Just arrived in the mail this morning!... I could have done with this years ago...

    This confirms the C55 uses the 208.374 centre muffler, but ironically the A202# rear muffler does not show up in EPC =) .

    The Sub frame is A202# and does not show up either but I'd bet its a clk55 sub frame... All other parts seem to be related to 208 CLK55 except that funny A208# air-air trans cooler?...which again doesn't show up in EPC..

    W208 sharing more than 70% parts with W202,

    CLK55 center muffler & rear muffler almost 99% the same, and can be swappable easily,,

    I think CLK55 using the Radiator cooler room (as trans. cooler), but not soo sure about that....!!

    On my 97' C36 I want to say its ME2.0

    All we did was code it to ignore faults via CAN from the ETC, since the type 6 was no longer there. That way, the ME didn't light up the check engine light causing me to fail emmisions test.

    With the ETC coded out and removed, at that point you can swap any diff ratio you want, because I don't think ESP would be able to tell. Mine was an ASR car.

    There's nothing measuring driveline speed, I believe traction control only focuses on the yaw rate sensor and looks to see if any of the 4 wheels are fluctuating speed.

    So again, Beckman can provide the custom coding to teach your ME 2.0 to ignore ETC communication as well as 5.4l mapping. Once you achieve that, you can slap any diff you want and any transmission that you can fit.

    Zayed,
    I trial fitted the CLK55 mufflers they do fit however not sure if the tips would be too high for C43 bumper.

    CLK55 uses a #202 radiator that combines trans cooler on right side, these have been known to fail in the 2002 - 2006 MB, I am not sure if this is susceptible to the same problems. It looks like I could run the cooler lines and radiator in the C43.

    Thanks Remo,
    So there could well be an easy way out for the manual setup on the C43!!, I will definitely have a chat with Beckman!

    Yes Paul, CLK55 rear muffler needs a little twist & top rubber mount bracket job to fit, soo easy,,

    CLK55 uses exactly the same C43 Radiator, but with C43 will not need the cooler holes for cool the trans.....

    Zayed,

    You have fitted CLK55 mufflers before?

    Yes the rear muffler top hanger needs "tweak" maybe 10mm to make it sit perfect, did you also modify the rubber hanger?

    That makes sense, EPC show the CLK55 radiator fitted(updated) to C43 but does not show cooler lines to use the internal cooler. The CLK55 one is in a new condition, I will use this but retain the original C43 trans cooler.

    Yes sure, i fitted CLK55 muffler in my friends C36, around "4" years ago,

    as i remember; we twist the muffler bracket & customized with lowered the top hanger to avoid touching the bumper, but honestly, not sure how many mm we lowered it,,

    trans. cooler is not a big thing, it depend to your optional to cool the trans....

    Neither of my C43's have the transmission cooler attached to the radiator. Just FYI (one is a 98 the other a 99).

    My 1994 C280 and 1994 E320 both had the attached transmission cooler.

    Zayed,
    Thanks, I may run a spacer too just in case the tips are too much heat for the bumper!

    Sulaco,
    Thanks for the info, I think I will keep the C43 cooler the way it is and plug up the holes on the CLK55 radiator, the C43 radiator I have has finer fins but they have been damaged by another owner whilst removing the viscous at some stage so would be nice to change it out.
