Period/Flatout best mod I've ever personally installed on ANY car (Yes it rivals ECU tune, the delivery & NEW available Monstrous/TQ vs stock TCU shifting prog is incomparable)

The shear terror unleashed by having this TCU mod is hard to put into words, I'm embarrassed to think I used to think this car was fast basically feels like the rear end is trying to rip the front end in half attempting to stand on its tail. The new Power unleashed early in ALL gears is intoxicating...

Now TRUE manual mode is enabled in cluster, by selecting thru C/S buttons
ALL shifts are firmed up like the AMG Speedshift ONLY A LOT fASTER + the pesky TQ limiters are GONE!

Marcin, of SPEEDRIVEN has lifted the TQ limiters so the ECU/TCU/ESP intrusion/TQ limiting in the 1st 800 or so RPM's that happens in every gear in STOCK TCU's is now GONE.

I couldn't believe the difference in overall acceleration, freeway was totally empty, I slowed to 30mph Sport mode 1st gear slowly rolled into full throttle never before has it thrown me back or taken my breath so violently for prolonged moments before, then WHAP 2nd gear it starts ALL over the pull is their again early in rpm's pinning you completely back to seat the entire ride, WHAP 3rd gear same freight train TQ blasting your back

(I'm thinking this is great! Love this mod, & not expecting 4th or 5th to pull freaky hard too but ohh hell yes they do I kept her pegged to 160ish It was still violently accelerating but damned speedo stops counting @ 160, I'm de-limitted I prolly hit 170-175 & coasted to 65 mph(in Mexico) the whole time w/this goofy look on my face.

I could go on & on, if you think your Tuned/modded 600/65 is the shizzy get this LATEST Version TCU from SPEEDRIVEN & report back here, I gotta admit I've been in some fast cars in my day (1 particular APS C6 Corvette TT w/built/forged motor made about 890 BHP it was the ONLY car until NOW that when I got out of it my hands were shaking for minutes afterwards...

Install is a snap, I was a full tard asking Marcin everything twice, but it's quite novice proof... That's it I'm gonna go wreak some havoc, feels like I bought a much faster/shifting/accelerating car that looks just like my old one

Thank you Marcin!!! Go get yours next!
SPEEDRIVEN's LATEST TCU program for SL/CL/S Soon for EV12 too

Is marcin a member here ?

Who is dsmed ???

Does Speeddriven have a website ??

Marcin seems to be the Albert Einstein of V12TTology

InTheBenz0

yeah contact info? Is it a flash like they do with an ecu tune?

And what is the price?

Benz-O-Rama

Do the firmer shifts only come in manual and sport mode? I'd like the ability to throw it into comfort when I don't want to snap my wife's head clean off her shoulders.

v10boost

I'm trying to change subject but man your signature is funny man.

Anyway, I would like to know their contact as well.

Thericker

This SPEEDRIVEN TCU tune/prog is totally different, drive civil in C/M/S & she reacts accordingly, put the hammer down & it's STILL not jerky just seamless downright frightening power. Power you've never felt before, because until recently it was locked away in the V12TT basement

Trust me I have nothing to gain here, I'm just passing on info about the latest mod I just put thru the ringer. It simply should've come stock like this, the original stock TCU is like a Model A in comparo...

Yes Marcin is "DSMED" Sponsor here on the boards, contact him for pricing

I've had OTHER TCU tunes in past on my C6 Corvette & multi other rides, problem w/those is they're just gimmicky KRAP that mostly increase "Line pressure" & give you a false sensation of speed (every shift is followed by a momentary mini sonic boom! total utter horse *****)

I just got mine installed yesterday. Holy wow!! I'll give a full write up when I have a little more time. Here's the sequence of events:

5:04 pm Marcin Installs SpeeDriven TCU

5:06 pm I'm driving in traffic and finally get onto the highway

5:07 pm I'm on the phone with the local drag strip inquiring about their schedule

5:18 pm I've burned a quarter tank of gas


This is the fastest my car has ever been. I now have both the SpeeDriven ECU and TCU mod. I'm going to the drag strip Thursday. I expect to easily better my 10.72

Thericker

Ahh yes!!!

See, I know what newfound unholy unbridled terror feels like, can't wait for you to SNAP off RENNtechs CL65 record

InTheBenz0

Where is he located, or can he do this anywhere cause its a set file as long as you have internet access.

MB_Forever

I'm very interested in this.... can someone please post a website, e-mail, or contact info? Do they do TCU for other models?

Ok, explain this to the dummy.....

I understand that TCU tuning can do a number of things, like firm up shifts and remove the torque limiter, but how is it adding horsepower? I understand that with the torque limiter removed, you have the ability to pump more torque through the tranny, but you'd have to tune the ECU for more hp/tq, no? I always thought that TCU tuning got rid of the lazy, soft, oem shifting and inserted snappy, race inspired shifting. You two are making it sound like you just gained 200 WHP.

Help me understand what's going on here.

DCMETRO22Z

Lol thanks. That's a true story. It was during summer 2005 in south france. I saw a 60 years old parking a silver SL65. I was kinda exited. I started to speak with him.

He told me he was kinda disappointed since he wanted to buy a powerful riva boat, and his wife really didn't want him to spend $500,000. So He decided to buy the SL65.for the half of the price of the boat.

V12Godspeed

Thats not fair , My car was made by speeddriven as well and I don't see it in the Media screen. I sence some favorite-tism here....

Thericker

Re-read my OP slowly, the 1st 800 rpm's in ANY gear are totally neutered in STOCK form IE the TCU/ESP nanny's pull the plug on the TQ output until AFTER those initial 800 rpm's in power band of ALL gears, so after TCU has ALL TQ limiters lifted every gear has found NEW untapped HP/TQ from 0-800 RPM's. Beyond that everything is improved vs stock...

That's my understanding of it anyway, Marcin will have to chime in as he his far better versed than I.

PS..No lie it actually feels like I gained more than the ECU tune, because these power gains are not just @ peak levels in RPM band but thru-out ANY/EVERY gear from 0-800 rpm's. It gives the car an entire new balance/aggressive nature like it lost 100's of lbs not kidding... @ 1st I asked Marcin if I was just imagining it, the gains are so impressive it's a shockingly different vehicle POST TCU mod...

Benz-O-Rama

Ok, so that makes sense to me. Basically, in 1st gear, and every gear after that, the first 800 RPMs are allowed all available torque to the rear wheels, whatever number that may be (based on your ecu tune).

So that leads me to the question of why did MB design it that way? What are the inherent risks associated with unleashing all available torque at the nanosecond of gear change?

Intriguing, nonetheless.....

Thericker

I'd imagine there main thoughts in doing this is saving Driveline half-shafts diff's etc...(As well as it would possibly put some older gentlemen who buy these vehicles in immediate hunt for Depends under garments) I highly doubt the stout Maybach tranny's we have will grenade. A FAR more powerful SL600 w/1300 odd HP is running this TCU tune w/zero failures.

I'm certain repeated assaults @ dragstrip w/sticky tires will pop a few half-shafts-diffs eventually as others have already done, but highly doubtfull anything will go using ONLY street tires or never running @ Dragstrip.

I'm going to Sacramento raceway either this wknd or next we'll see what comes

Gondon

So noob drivers don't crash it because they cant handle all that power.

Sunir

ricker/marcin...

Is this tune available for SL55 as well? do we also have the first 800rpms in each gear impaired in stock form as well?

Thericker

ALL high powered MB's have this castration, I'd imagine it's probably going to be the MOST dramatic in a tuned V12TT as the TQ is already redonk! But nevertheless a power/speed robbing dilemma in ALL models.. Contact Marcin, he's a bit busy right now but these TCU mods are coming for you 55k guys too

SL600 V12TT

Do they do ECU as well?

bassn_07

Awesome Sean and I post with both jealousy and envy. I'm glad to see you TT guys finally starting to unleash the true potential behind the beast. Can't wait for Saturday!!!!!

Thericker

You've got nothing to be jealous of bud! You've set the bar for many of us.. I can't wait for Thurs to see WTF Marko does

DCMETRO22Z

Speedriven seems to sell exactly the same Intercoolers as VRP.

MarkoCL65

They were manufacturing those intercoolers for VRP at one time but are now selling their product directly.
