Mercedes Performance enthusiasts. I did a quick video of the TCU tuning process from an end user perspective. Thanks!

Rehabguy

You, sir, like to live dangerously Public wifi, debit card info and letting some unknown person tweak your TCU. Looking fwd to seeing the next video! Hope it worked out well!

How do I get in contact with this Russian hacker ? I would love to try this out on my E550 please dm me !

SAMzE63s

so whoooo did it?
how much?
results!?
talk to us loool

He can't respond. Computer is hacked, bank account empty, and charge card maxed out. Just kidding, hope it worked and you are still financially secure and you have no future issues. But, seriously, would never knowingly give someone access to my computer or cars ECU/TCU.

Yikes - this is a video on identifying and treating anxiety

57000 rubles ~$750 plus Openport 2.0 clone, and fees for conversion from dollars to rubles all in about $800.

It's definitely quicker. I like how it shifts better. I think I was on an older TCU program from MB, and it kind of felt clunky 1-2-3, and at some point when I would add more power it felt like it was actually getting slower in terms of actually putting it down.

More purposeful forward acceleration power from stop. I didn't like the TCU tune with the OE tune, but the OE bench tune never felt perfectly tailored for my particular car. TCU + ECU tune felt very fast but it also felt like I needed to service the transmission, so I'll run down a transmission drain refill w/liquid moly plus some valve bodies.

I went back to stock ECU and am just running TCU tune until I do transmission work. I think I may try a custom tune after. That being said I am surprised at how much quicker the TCU tune makes the car. TCU plus stock ECU feels good.

I'd guess a TCU tuned with ECU stock is about as quick as an ECU tuned car to 60mph (ECU Tune feels faster above 75mph). I haven't measured on dragy yet but real world I can launch better and pulls away from standing quicker.

With just ECU tune I had to launch the car perfectly or it would just spin, cut power and I felt like a loser. TCU tuned puts down power well, I hit the gas at a stoplight and she just goes.

I guess I should put down some times with dragy and post here again.

ha! I know what you mean. Especially in these days of increased focus on cyber security. I did run a malware scan after and check my bank account for a few days. I also started to mine crypto currency after this video to help offset any potential losses from public wifi/internet tuning and meme stocks.

apt observation -- in fact it is almost time for my Dr's apt. lol

ha! yeah man.

ha, thanks man!

EC's TCU tune made my E550 .4 quicker in 1/4 mile (11.7 to 11.3) with +3mph out the back.

Let us know how the trans service works out. Im going in to my dealer on Wednesday to double check the fluid level and check for newer software. My trans doesnt feel normal with my O.E. Tune downloaded. Good to hear the TCU tune feels better with stock ECU. Im hoping an update to my trans will make it work better with my tune.

When attempting to brake boost, how far can you get the RPM up to with this TCU tune? 3 rpm range?

nota_amg

I launch around 2000rpm, and with 245/285 street tires it still spins all the tires. the converter would never let you get anywhere near 3k rpm. people are twisting/breaking their transmission output shaft when launching at/above 2,200, so I'm good with 1,950-2,000 rpm launches.

E550Amg

You got TCU tune? If so by whom? I know Starline's TCU tune let's you launch at 3rpm.

SAMzE63s

not sure if you wanna do that. With the TCU tune you have A LOT more torque in first and launching at 3k rpm you’re just asking for something to break.

nota_amg

I have EuroCharged TCU Tune
Also, no CLS/E 550/500 runs 10.4 in the 1/4 without some MAJOR mods... 😂

E550Amg

Ya no **** sherlock 😂 lol
@cls5504matic let us know how far this tune let's you Rev the RPM while brake boosting pls.

cls5504matic

Startline’s work is great on the platform. its not as modded as you might imagine just methanol, m157 hybrid turbos, downpipes, and ecu/tcu tune to get 800hp and 10.49 on the street in a cls500/550

It is interesting to compare their e63 build, 10.30 in the quarter and 850hp.

They even say they are running the stock intake

cls5504matic

let me do some transmission work first and i’ll do that.

I have the filter and liquid moly and debating putting in new blue cap (k1 k2 k3 and torque lockup) solenoids too.

cls5504matic

I’ve read here i should at 1.5k and be good. Without ecu tune do you think it would be safe?

cls5504matic

Ok I talked with Morendi a bit today. He mentioned that 2300 RPM is what they felt the torque limiter was hardware limited at unless the turbines were clipped. So I guess I was wrong about the Startline Motors cars not being very modified. Seems they are modding them beyond what is listed on dragy.

RIP M5

Sent you a pm, op. Thanks for the review

PeterUbers

If I launch more than 1750 I get wheel bounce and the trans disengages and goes into neutral until I turn the car off and then on again

$0.02
edok tcu tune

billvp218

Is that a feature or a bug?

PeterUbers

based on posts on a separate tcu forum it seems to be an inherent protection built into the 722.x trans since many tcu users experience similar thing

so like a trans thing not a tcu tune thing
