Gentlemen,

Before I ask your opinion I'd like to give you some background on me and my Black.

I've owned my silver black series for about 6 years now and have put about 20k trouble free miles bringing the car's mileage to 56k.

It's not my only car and I recently had to make the decision whether to sell my 2015 Z06 or the Black to be able to afford the new 991.2 GT3 (in manual of course).

I've never really been into american performance cars but man these new fully loaded corvettes can really hold their own..

Anyway; both cars are at about the same value ($70k ish - maybe optimistic for the black) but the corvette is on it's way down and I believe the Black its way up.

The corvette doesn't feel anywhere near as special as the Black series so as much as I'll miss the Z06 I could have never given up on the black beauty.

SO.. I have this bone stock Black and am absolutely in love with it. I ONLY drive with traction control if it's raining so this thing ALWAYS puts a smile on my face. I usually go through a set of rear tires every 5k miles.. almost as if this thing was made to slide sideways lol

HOWEVER, I'm sure my main complaint with the car is similar to many of yours... the transmission

I know the 2012 C63 Black series uses the same transmission but is tuned a bit differently so has much quicker shifts and I believe matches revs quite nicely when down shifting.

I'm sure Mercedes could tune my ECU to the 2012 C Black specs OR could go with a company like Weistec's Rev Match Tune or something similar.

I am worried however it could have an adverse effect on the value of the CLK.. I would think the Mercedes Tune would make a future potential buyer (probably will never actually sell) more comfortable but might still scare away.

Also - would the tune cause the engine to wear faster?

What do you guys think?

Thanks

Hey Alan,

Good questions. The black c63 is one of my favorite cars for sure, and we have owned a few of them.

The car does need a little more pep, and the tune sure does help with that. It won't have any adverse effect, minus the tire problem as indicated above.

We actually have locations in Austin and Houston if you wanna stop by and chat in person

 

$70's for a 56K mi BS is optimistic, IMO. That said, I'd sacrifice the Z06 for the 991.2 GT3. There's more depreciation left in the Z06 whereas the BS has leveled off. I personally don't think the rev match will negatively affect the resale value but like anything else, buyers will try to use it as a pretext for knocking off a few bucks even though they actually are happy it comes with the car. And if I'm not mistaken, the rev match is a reversible mod.

 

I have had the rev match blip throttle downshift for a couple of years now and to me it transformed the car, in sport and manual mode it sifts WAY faster than stock "manual mode is best for heated driving", it's NOT a Weistec TCU tune but i can't remember the two guys who flew over from Germany to tune the trans for me and a few others, Im also running a Eurocharged tune on my car and have been for about three years now with no problems at all...I'll never sell it...

 

Where's your Houston location?

Do you guys get Ralf and his partner to fly in fro the blip or do you use their software?

 

Yea I agree I'd have a hard time finding a buyer at $70k for the Black even with my impeccable service records and being meticulous about doing A and B services when scheduled at certified Mercedes dealerships..

Sold the Z06 yesterday actually for $67k.. would've preferred 70k obviously but it was a quick sale and I didn't have to shell out $2k for new tires as I was expecting to be asked to.

The pain of the Z06 loss is heavy but definitely overshadowed by the excitement of a stick shift GT3

 

Was it Ralf and the other guy?

Did they do the install at Eurocharged Houston?

Did you HAVE to do the Eurocharged ECU tune for the throttle blip to work correctly?

Thanks

 

C63 BS (7G MCT double cluth) does not have the same transmission than CLK BS (7G with torque converter)

TCU tune can improve shifting time and add re matching but the hardware stay different.

I had the TCU, ECU + rev mathcing tune from Ralf on my previous CLK 63 (non BS) for more than 2 years without any issue.

 

Thanks for the info.. any idea how to get in touch with Ralf?

 

Thanks for the help guys.. I guess it's a no brainer

Now I just have to figure what company to go with

 

Have you considered the Dime Racing rev match? Not sure how it compares to Ralf or Weistec. Only asking because they recently posted below:

https://mbworld.org/forums/clk63-bla...me-racing.html

 

Yes it was Ralf and his mate, I can't fault the work they did, if you want to see what its like PM me and we can meet up somewhere.. I'm sure they will all be similar to each other..

No you don't need any ECU tune to make the TCU tune work,

Yes they did it at the Eurocharged location,

 

Actually spoke with them today and they'll do just the TCU since I already have my ECU tuned by Eurocharged.

And Steve the owner of this company actually used to own Weistec so lots of credibility there.. I'm pretty excited

 

I am really surprised. I remember when Ralf and his mate added blip o my previous CLK 63 (non BS) TCU and ECU needed to be updated.

From what Ralf told me. They need to modify both ECU and the TCU.
CLK63 B(BS or not) have not this feature ON in software, so they modify standard (or optimise if you already have an tuned ECU) software with part of 63AMG software (with blip throttle feature as C63) to activate it. It is a merge software for ECU and TCU

 

Well Eurocharged used to match their V5 ECU tune to Ralf's TCU tune back when they would do work together.. but that hasn't been for several years.

Eurocharged V6 is the newest version of their ECU tune and it comes with a rev match feature but it is not as aggressive as I'd like it to be.. I suppose that's because I need the TCU too.

And this company Dime Racing is owned by Steve of Weistec. A few years ago Weistec would offer their clients TCU tunes by Ralf as well

 

I agree this modification is one of the best you can do for the car.

 

So does anyone actually know if there is a difference between the rev match tunes that are available? Weistec vs Dime etc? Or are they all they same tune?

 

The only way to know for sure is to compare each tune via a MD5 Hash perspective. Outside of that, I think each Tuner made it their "own" by changing the variable parameters available in the software. Some are conservative and some are more aggressive in these settings available to them. This is simply my opinion on the matter. I have not proof either way.

If you are on the hunt to find the "best" one, its very subjective based on how you like your car to respond. To talk the owner or ride in a car that has each one of these Tuner's tune to fully understand what the tune could give your driving experience.

Best of luck!

 

+1

 

 

Same for me

 

I would of kept mine if it shifted like my C63 BS. Did you end up getting the rev match?

 

Yes I got it with aggressive settings (more louder than stock C BS) and I love it

 

 

Dime still offers the tune. Today I received the hardware from Dime to do a remote TCU tune for rev matching. Hoping to get it completed this weekend. If it works on a 2008 E63 I would think it would work on a CLK BS
