I didn't know that the c36 was equipped with an LSD. Question??? Who did the Flash to your ETC module?

hcetzneb

i had a guy in new york do it.... see i didnt want it to be flashed with any new s/w just have the ratio flashed in and he is very handy with computers he was able to find the gear ratio in the program and modify it.... but i know kleeman does it and rentech to most
tunners who are capable of flashing the me should be able to... its just alittle more tricky.
....And the good thing about the c36 diff is is a direct bolt in you just have to swap the front yoke everything works axles driveshalft .... if any one is interested i have a extra new one i think with laying around

Found the pic of the insides of a stock diff. i believe the spacing between the gears was 33mm?
If they send new gears with a phantomgrip then that would workout great or an ETC flash.
I heard that Kleemann will actually just machine down your own gears so it would be a specific grip. Just hear say

I wanted to suggest that you could also run a standalone transmission control. I have been testing this idea. It would also afford more transmission control. As in shift points and firmness and full manual mode. PM me if you are interested.

...could you separate the TCU with the engine ECU or would everything have to go standalone? Being no expert, I thought both ECU/TCU worked off of each others data. Would the ECU notice there is no transmission or is that something you work into the standalone?

I have always loved the flat bottom DTM steering wheels and if one could wire a standalone TCU to run manually using the maybe the F1 paddles would be just sick..

To keep on topic...after I buy some DRs and 17"s for the spring I'm going for an LSD. I have had my heart set on sending mine to phantom grip also. Its 50-75% less than the next one, and it seems to be the same design as kleemann for 75% less. Quaiffe unfortunalty doesn't fit.

I believe one of the factors the transmission uses for shifting is the MAF Voltage signal. That being the case, the ECU/TCU would have to be tied in together

whipplem104

Some of the initial tests I have done suggest that it will work. I actually left the tcu installed and just unplugged it from the transmission. The system did not go into limp mode and the car drove just fine, except not changing gears. I am going to wire up some more tests for each gear. If the ecu and traction control do not care about the transmission then I will wire up a standalone. I have not gone further yet but if there is some serious interest, I will.

As far as paddle shifters go. Any input can be used. I was just taking apart a newer style paddle shifter to see how to wire it up for use in my car. It looks as though it will work.

I have a thread on this subject so as not to hijack this one.

There's a standalone kit for the 722.6 transmissions. Currently only one MB owner is using it in a MB car but he definitely knows his stuff. The only thing that would be annoying is you would have to eliminate the no-start relay and 4000rpm under 20mph rev limiter since the factory TCU will be eliminated. The controller can control all the other things like back-up lights so it wont be junked out.

EDIT: /\There he is . I know for a fact that you can deactivate the ABS and ETC on a e55 by unplugging the ABS pump and all it does is give you some idiot lights, the car other wise functions normally with a bit more fun involved .

whipplem104... what year car are you doing your testing on. Is it tip shift or a gate shifter. This sounds like it will conflict with the engine control unit. Just asking.

There will be an update on the Factory LSD tomorrow if I get the seals I ordered.

whipplem104

It is a 1998 with the gate shifter. I even thought that if the later cars would do the same then the shifter could be replaced if we could not get it to work. I will have to do some more testing but so far the factory tcu does not seem to care about the valve body being unplugged. It did not set any limp codes. I am going to get another harness and wire it up and take a drive to see if anything goes wrong.
I talked to PCS today and they said that they may have a chance to get back to working on the issues that still remain. Once they get the speed sensors set up, there will be gear recognition which should make it pretty much 100%.
I was thinking that if people were interested they should call PCS in order for them to understand the potential demand.
I am planning on starting to drive my car again shortly after the engine is back together and I will start working on the tuning from my end some more.

That sounds pretty good. But I don't see myself going that hard on getting things to work. Great job all the way around though as a hole for the progression in options for these merc's.

This is the new LSD trim that I pieced back together. I have alot of paint and the silver can was the only one full enough for coverage. So if you don't like it buy me some more paint. The diff was sourced from a 300CE, the year I'm not sure but it had the 3.07 ratio and the 124 housing I needed. I disassembled it and transplanted the LSD guts from the 190E into the new diff. using the 300CE housing, Ring gear and drive pinion. I used the new 190E flanges, new front yoke and rear modified cover.


RESULTS: The LSD Works First drive was slow because I wanted to properly lubricate the clutches. But the ride home was much nicer. In the turns it just seemed to pull right out with no hesitation and the burn out was nice and smokey with two tires turning.

This application will work on many cars with bolt-on axles just by altering different pieces to make it fit. The only problem is locating an LSD.

I HOPE THIS HELPS ANYONE LOOKING FOR SOME SMOKE

^ Wow!! Great work!

I went ahead and got a few friends to record a Factory LSD burnout
Enjoy

Does anyone know if it is possible to change the thread title??? Seeing how it works now

hcetzneb

Nice work money... exhaust sounds good. Did you have the car in drive or manual 1st

money-one

The car was in drive and ESP off.
Side note it was cold as f*** outside and it may look like I'm burning oil but believe me I'm not.

NitrogenBalance

how much did this cost? Time if parts where there? Cost of parts?

money-one

The LSD 3.27........$300 from ebay
Driveshaft.............$190 from Potomac German Auto
Driveshaft Flange...$72 new from dealer
Rear cover............$50 new from dealer
The two new part prices may be reversed. Its been too long and now I have an extra rear cover from the open diff. I could of used
Open Diff. 3.07......$70 salvage yard
Lsd oil..................$20? quart not a 100% I didnt pay for that
Side seals.............$12 new from dealer

Not including the great paint job I would say it took about 3 hours to do the whole thing and that would include the removing the old diff. and shaft, putting the LSD together, re-installation with other rear shaft and diff. and fillup with gear oil.

Keep in mind that I am a mercedes benz tech. I have a lift, and have had the diff. assy in/out several times

The factory LSD you are using has the 185mm ring gear in the smaller housing? 3.27 or 3.07 ratio? Did you have to reprogram the TCU for a gear change? Nice work.

money-one

This was the smaller housing/ring gear set up is found in many of the older, smaller displacement engines (V6 and smaller). They were also found on some of the early 203 chassis before they made a chassis specific one in the later years.This is the 3.07 ring gear ratio which the C43 came with stock. That is why I needed to reduce the 3.27 LSD to a 3.07 in order for it to work. There has been nothing reprogarmed or flashed. Just bolted it up and drive.

taxi driver

Hi money-one, thanks for showing and sharing gets me wanting a LSD also,
(very describing and good pictures too)

Now there is one or two Q. the new diff has 185 ring gear right ? What is the C43 messures and are there no MB LSD internals that go into the stock diff?

When you replaced the driveshaft flange did you just retighten it w a new nut or did you change the spacer bushing # 71 too ? Roger

money-one

To the best of my knowledge it is. Ill check tomorrow on both to verify everything. From what I am aware of there are none. Mercedes saw it fit not to equip their cars especially on their AMG's until recently. The C63, SL65 are the new ones and the older ones were the 190e 16v year specific and one more an older SL not certain. No factory LSD will fit in the stock C43 housing. Believe me I know. The seal was never replaced because i never went that far into the assy. I think that is the crush washer and if you got a good impact you will know when to stop tightening.

hey money-one
i have a 2000 clk430 and will this setup work on my car??
what would i have to change?

thanks
Liran

money-one

I believe your car is equiped with the 210 diff housing. When I refer to 210 I mean there is a part number casted into it that starts with that number. I'm not sure which diff. flange spread you would have but i think it is the medium one (there are 3). If i am correct then this exact setup would work but you would have to locate the correct gear ratio and then do the transplant like I did. Or you could always send out your ETC and have it programmed $$$$.

hi money one! i own a c36 amg with no esp or asr is a 93 model and want to swap the lsd stuff, im a benz tech man too, in spain. did you use original parts? could you tell me the number parts did you use?thanx
