The 3.06 fits in the diff just fine... it’s the same ring and pinion as used in the slk55/clk55/c55 which is basically the same unit as in the c63 ( don’t remember what the e63 uses for a housing but I believe it’s the same hag215 axle design
I don’t think the Chrysler has the same housing so I doubt you can just bolt the entire chrysler unit in but I may be wrong if you can that would be the way to go if you can find one with a lsd and just bolt the unit in

So who can I just pay to do this for me lol

The diff is the easy part. Good luck on the TCU/ABS/ESC programming.

yfz rock

has anyone done this other then the e63 also track times before and after?

TCU tuning is now pretty available - @5soko in NY/Tri-State does it, and I can also do it. Couple other places here and there as well!

Thanks!

I understand that TCU tuning for faster shifts and increased line pressures is available. I’ve had mine tuned since 2015.

However what we’re talking about here is getting a shorter final drive gear to get along with the TCU, ABS and ESC units. 3.06 modified vs 2.82 stock. Without correct coding for all three, it won’t work at all. (see above)

Are you saying that EC can do this for the TCU? And could you explain how exactly please? What about the other dependent control modules?

GLK350 rwd came with a 3.27 final drive differential.
Since it’s based off the w204, would this swap in?

What I would like to know is if the TCU from 2007 E63 (M156-W211) can be re-flashed/programmed via directly connecting to the electrical connector or via the OBD socket? The TCU for this sits inside the Transmission on top of the Valve Body and has an electrical connector that sticks out on the Passenger Side Front and fits through a hole from the bottom of the Tranny. The make of the TCU is Siemans VDO, Part # A 033 846 73 32, VGS2-NAG2. I've been told that "Tony" from Race IQ in Atlanta can do this but after talking with one his associates who operates locally here in S. Florida told me that he doesn't think it can be done??? He of course hasn't returned my call either. I'm sitting here about to replace the Rear Bushings, Hubs, Flanges Rotors and have the bits to rebuild the E63 differential. I also bought a Diff from a 2005-2007 SRT8 from Challenger, 300C with 3.06 Gears, but I'm holding back on getting a LSD until I know I can get the TCU calibration done for 2.82 to 3.06 Rear diff ratio??

Can someone let me know if the have a similar TCU and have had this swap done successfully? If so, please let me know who I should get in touch with to have my TCU recalibrated?

Getting ready for a Hurricane tonight, so I'll be hunkered down waiting for an answer!!!

Pyromaniak

Need Ktag read to change final gear ratio. Its possible to change it

E63007

What's Ktag?

Pyromaniak

K-tag is device for Engine control unit and transmission unit reading and writing. Peoples who made chiptuning have it.

roadtalontsi

ofcourse it can be done and has been done.

Only you would question a Forum Sponsor/Vendor in such a condescending manner... I bet you're parents are real proud of the ****ing douche they raised. But if they're from Ontario too, it's par for course.

Celicasaur

Howwwww on earth was this condescending?!

Believe it or not, he was being very sincere here and his questions/points-raised were perfectly rational ^

Celicasaur

Sorry replying so late to you.

Ok so I had the diffs removed out of both casings because i needed to mate the AMG lsd to the Chrysler ring n pinion...which then meant homing them both as one unit into the Chrysler casing. I hope that helps to clear things up. You do however need to use the AMG flange which connects the diff to the propshaft.

Here's a quote of mine from the OP:

"After the shop had done the work (new bearings installed of course), it was time to finally fit the 3.06 ring gear and LSD into the Chrysler casing which now has the AMG propshaft flange."

BLKROKT

*** off

BLKROKT

Thanks dude, I was just asking a question. Guy needs to relax.

So the question wasn’t answered either which is interesting. Do you really think the required TCU coding for this can be done via OBD2? What else, probably ABS/ESC too? I didn’t think so but I’d be happy to be wrong here...

Celicasaur

From what I understood, it simply wasn't possible to do it via ODB2, hence why the TCU needed to be physically removed. But hey...technology improves over time and maybe somebody has found a way. One thing is for sure though - we'll start seeing a lot more people running a final drive upgrade if/when it really is as simple as plugging into the ODB2 port for the tune. It's the tuning aspect which makes this mod such a PITA.

Worth mentioning though, I remember a little while back that RENNtech claimed they could tune the TCU on the W212 turbo cars via ODB (torque limiters and all that jazz, I didn't see anything about gear ratio's though). Maybe something exists, but it hasn't gone mainstream yet

Jasonoff

It's ok. You didn't understand the legit technical question and assumed it was condescending. It happens.

DavesMeanE's

The tuning that @5soko and myself offer allows exactly what this thread is about In addition to all the benefits of a TCU tune like faster times, better, smoother shifting, higher line pressure, etc. You do have the ability to change your final drive if you'd like to something more aggressive. All software changes, all done through the OBD2 port.

Let me know if you have any questions!

Thanks!

This is great news for the community tbh.

3.06 or 3.27 with a 7600rpm auto-shift would be so nice going WOT from 70mph-1000mph.

BLKROKT

That’s a slam-dunk then, thanks @DavesMeanE's

When are you guys back in CA - this can only be done in-person, right?

Jasonoff

@DavesMeanE's, do you know if Eurocharged Canada will have this capability at some point?

DavesMeanE's

Toronto can do it currently - Get in touch with Slav.

Thanks!
