Anybody have any experience with it?

http://weistec.com/all/c/c-63/2008-2...u-upgrade.html

Curious to know how much faster the shifts really are?

And, I've got the Eurocharged V5 Tune, will the "Blip-Downshift" still work with this? I guess this one's harder to confirm, but just curious to see if anybody knows.

Thanks!

My car is about to go under the knife for this. Will let you know in March. I haven't seen much feedback on it here.

The 'blip-downshift' is just an ECU trick, and has nothing to do with the TCU. For the upgrade, Weistec modifies both the valve body and TCU to truly rev-match on shifts. Different things.

Yup, I'm aware of the Blip Downshift being an ECU Trick.

Curious to know as to whether that'll interfere with the actual Weistec Transmission when they recode the TCU to truly rev-match and what-not.

Interesting! I look forward to it! I come from VWs, so I'm used to a DSG. But, having a DSG Flash vs not having a DSG Flash, made a pretty significant difference. Granted, that was only about $750.

But, if it can have anything like the effect of a DSG Flash does for the DSG Transmissions, I think it's worth it.

Good reads. Guess people does say it shifts better. Will wait for your experiences to see!

Since you also have Eurocharged too!

it will never shift as good as the dsg

merc build **** transmissions but killer engines its just a fact

but yes it will shift faster

Phil Chow

Yup, I'm aware it'll never be as fast as a DSG. Was just referring to the Weistec TCU/Valve Body being a very noticeable upgrade in terms of shifting speed and everything.

Keep me posted about this!

The fact that the MCT can handle a Stage 3 Weistec Supercharger shows that Mercedes does make very good transmissions.

Been tossing the idea of this upgrade around. More than anything wanting the increased line pressure to the clutches to hopefully hold the extra power from the recently added headers.
At today's exchange rates, a stage 2 blower setup is a loooong ways off lol.

The upgrade "should" suffice what I'm looking for? Only do a few 1/4 miles runs (if any) a year, all just street driving. No real "digs", just some roll on's at speed to hear them headers sing the songs of my people (yes I'm German ).

You shouldn't 'need' the VB/TCU upgrade to hold the power for a headers car. If your trans isn't liking your headers, IMO you have bigger problems than this can fix.

I've got well over 100 1/4 mile passes and a bunch of trackdays on my MCT, and it never slips. It gets grumpy after a full trackday, but no problem holding the power. I'm doing this primarily for the performance benefits on track (quicker/harder shifts, rev-matching) in conjunction with the upgraded trans pan.

Just my 0.02

when you compare autotransmissions between all the euros bmw audi vw and mercedes Mercedes is last on the list when it comes to performance

Its a fact

Sorry, perhaps I didn't phrase it properly. NOT having any issues currently, just thought the TCU upgrade would be more like preventive maintenance and avoid/prolong any future issues.
