Are you saying that you got the 306 gearing to work on the E55 , no matter where the file came from, without need of StarDas ?

urbamworm

Dyno, where in Italy are you located?

chawkins2001

Have you done the swap already?

dyno

really a long story:
I begun looking for that P98 differential (as it was originally named by amg) back in 2007 ..
In late 2008 iirc I opened a thread about the many problems ..
Got it to work just not long ago as I am getting back again with modding this car, hopefully.
I still have the tcu socketed so as to swap quickly different eprom/files, as I would want to test some mods that I asked recently to make in my file..


I'm in Bologna

Also posting this in this thread in the W208/W209 section

Edit: updated the photos below to indicate proper name for the suspension module.

So with the help of my trusty assistants, I took apart the panel on my 2005.5 E55 AMG (sliding cup holder covers, not split). I don't know that the SAM module has anything to do with this but I labeled it anyway.

What I found is that my car has TCU part number 034 545 15 32 - which I didn't even have on my list on Page 3 of this thread.

Here are all my guesses following this:
- If I keep my stock 2.63 rear gears and switch to a 034 545 10 32 TCU, I can probably do burnouts.
- If I swap to 3.06 rear gears and switch to a C55 or CLK55 TCU <part numbers needed here> I can probably do burnouts.
- If I swap to 3.06 rear gears, I can drive the car with <insert part numbers here> without throwing limp codes, but can't do burnouts.

Tempted to order a 034 545 10 32 TCU to test this with my stock gears first, unless there's someone in Colorado/Denver that has an 03-04 E55 AMG that can do burnouts that wants to get together and swap TCUs to test this!

Y don t you try putting in Dyno mode ?


i m not usual doing burnouts so can t help more.
FYI you have the same EGS-tcu as Cls55
- Suspension module is one thing.
Abs-ESP module is another thing and you can find it close to the main SAM in the engine compartmnt

Tremek

I want to be able to turn off ESP and do this at the track instead of keying the car on and off and messing with wheel commands.

chawkins2001

There is more too it than just throwing in a CLK55 or C55 tcu, sure it will work but you will have another obstacle of issues that I had that come with that platforms tcu.

1) That tcu will shift your car at 5850-6000rpms
2) The TQ limiters on that TCU are that of a N/A motor, and now where near the E55. You will need that adjusted just to get it back up to E55 spec. Just by throwing in the M113 TCU from those platfroms, I also showed my traps to be slower by 5mph, and my dyno numbers to be down considerably.

If you want it done right, get a TCU tune, and to date, there is only one vendor that has done it successfully for me.

With the TCU now back up to E55 spec, plus his TCU tune, and the 3.06 gear, the car definitely accelerates faster. PM me if you want his contact information.

You've got a few mistakes in your photo labels.

The item with the blue square drawn around it is the AirMatic module. That's the one you mess with when you install an electronic lowering module in these cars. I don't think it has any relevant function for TCU or burnouts.

There is an ESL module, but it located in the engine compartment next to the ECU. I'm not sure if it will have any positive effect for this issue...I tried swapping an older E55 unit into my 2006 E55 and the dashboard lit up with all sorts of error codes and didn't work at all.

Here's a simple table that shows you the TCU versions that you need to be concerned with for the E55... The two "green" part numbers are confirmed to allow brakestand burnouts, and the three "red" ones are documented to prevent brakestand burnouts.



I know that user adianaty swapped in the A 034 545 10 32 into his late model E55 and indicated that it was a complete success....he smoked the tires down to the cords, where previously it was impossible with his 2005-2006 TCU module.

The "EGS52"-based TCU modules are allegedly programmable, so with the help of Jerry (EuroCharged) you might be able to simply load the firmware file from one of the older TCUs (the green ones) into a newer TCU and effectively make it act like the older TCU without actually swapping out any hardware.... I haven't confirmed this with Jerry, but since he already does TCU programming, it seems entirely plausible that he could build a new TCU image file from a 2003 or 2004 image, and put that on any TCU in this list.

Greg, this is killer! I will make changes on those photos and update accordingly so we don't get bad data out there in the future.

Edit: relevant to this thread - I would like to capture that same data for the CLK55 and C55 TCUs so that for the 3.06 swaps, at least we know the baseline TCUs that will work with the 3.06 swaps AND allow for brake-stand burnouts, even if they also need a TCU tune to account for torque management, etc.

Edit #2: Just bought a TCU # A 033 454 14 32 - expect it will be here by next Monday, will report back on brake stands. Would love to find out from Jerry at EuroCharged or Cory at Kleemann if this TCU can be massaged for 3.06 gears.

dyno

Greg, this is good info. now I see why it was so difficult to make burnouts with my cls..

I looked in my bag and found I have an 033 545 14 32 I bought as spare.
unforunately to test this burnout thing I have now to have it reprogrammed for 306

anybody there with a file from a clkDTM )

dyno

from the attached scheme seems more like what's important for burnouts is not the TCU but the ESP module (N47/5) who receives data from each wheel sensor (L6) and the SBC brake unit (A7/3).
I think you'll have to synch the TCU A 033 454 14 32 you are waiting to your car VIN through DAS .
.. even if, I suppose that Jerry/EC should already have its file, considering all their Tcu tuning with many customers and maybe he has an easier chance to do the test.

in any case, Let's know the result. Curious at this point !

chawkins2001

Andy at MHP did my TCU tune and 3.06 gear calibration and worked.

MRAMG1

Glad to hear it worked my friend

Zod

more like He found some one that could and used them and charged you...

none the less i suppose you got what you wanted

Tremek

So a minor setback. Got the TCU, installed it - and the car won't even crank with the new TCU plugged in. Plug in the original TCU and the car starts right up.

Is there any process to install the new TCU that I'm not doing - a reset or something? Is it possible this TCU is either dead or won't work for this car at all? Model is A 033 454 14 32.

Edit:
Can anyone confirm whether this is required?

adianaty

Hey guys, Greg is correct that I used a 0325451032 in my 2006 and can do brake stands all day. Its currently out of the car since my other TCU is tuned so if someone wants to try it out, let me know and I don't mind shipping it out as long as it comes back intact. I did not need to do any VIN inputs in STAR and as far as I know, Eurocharged sends out spare tcu's to customers often when they can't afford downtime with no VIN numbering...

dyno

so, are you saying that you took that TCu from a salvage car, then you just plugged in and it worked ?
.. really don't think so !

PACougar

Please grace us with your knowledge, why don't you think so?

adianaty

You want a video. Ran it in my car for a good 3 months that way. I can swap them readily and I wouldn't offer it up to anyone to try unless it worked...

Craig, didn't you just install the n/a tcu without having to do any coding in star?

dyno

again, YES

either you have the ability to WRITE into the serial eprom of that TCU (that's indeed 0335451432) your car VIN #
OR
you need somebody with a Star to synch it .


need proof ? OK
.. this is the HEX screenshot of that eeprom and you can see it contains the VIN.

PACougar

So you're saying you've physically tried swapping them and it didn't work?

adianaty

Yes the TCU carries the VIN in the eeprom, so does the audio system. Last I remember just because it is in the audio system and I replaced it with another it didn't mean that I couldn't start the car. Key place to look is the startup checks for ignition in the ME. Once you find that HEX feel free to report back what you found and I will bet you a Bologna sandwich that there is no VIN specific checks done on the TCU for startup at least on my 2006 E55 car. Maybe there are exceptions but I wouldn't call what you have as definitive proof given my results and those from others. Jerry from EC at one point was running my TCU out of my 2006 in his car to make sure the tune was right and he didn't change VIN's in it to make it work. I'm simply providing my real world experience with this since I went ahead and spent my own money on proving it. Feel free not to believe it.

My guess is Tremek has a bad TCU.

dyno

Steve, really can't get why it matters for you how people is organising their business.

for me it just count the quality of the end result.

If that' s being proven, then its OK.


I don't know how Chawkins car is really working and if it does or not BOs

me, I 'am happy with my 306 and here' proof it's working:

this WE while travelling to Venice I took this pic

it shows my car running 100 KmH @ 2500 Rpm in 4th gear.



math is simple ... and i even wrote a detailed post but just lost it while uploading the post ...


a standard E/CLS with 2.65 ratio should show 100KmH x 3.06/2.65 = 115 KmH @ 2500Rpm in 4th gear ..

dyno

Tremek said his one is not working ...

as i wrote before, I have this spare tcu that I bought for the hardware but I didn't try to fit also because it will not work for the reason it is not reprogrammed for 306.

should go down in the garage and give a try whether it starts .. but is really late here.

but anybody can try to swap a friends TCU quite easily ..
