TCU Tune
What was the first thing you noticed?
Was it worth it?
Who is the tuner?
Are you satisfied with your purchase?
Thanks for any responses.
Most people dont understand the TCU, and are just asking or jumping on board, because its the NEW keyword they are hearing....
One thing about MB, is they designs and over engineer there systems to definitely protect the car (engine, transmission) , when it comes to the TCU, there are scenarios when a TCU tune would benifit , and most others it wont, and is just a waste of money.
Worse, setting yourself up for some failures.
As @skratch77 has stated , with a decent tune, you cant get enough grip on the rear-end to even justify trying to put more down.
So I guess there are those, that just want to say, hey I got it ... I for one, am staying away from it.
I am open to changing my mind. That is why I wanted someone with the TCU tune to chime in with their experience.
I never thought of it like that. Last thing I would want is my tuned engine tearing up my transmission. I am sure a new transmission is pretty costly. Does anyone upgrade there transmission?
I would think that is only relevant if your trying to push major power.

Yes same here.
I have seen tons of threads talking about it and all the claims but have not heard one persons experience. I think one thread talked about having to have whatsapp and the tune in order to be in their special group
I am an interested consumer. Just want some real world feedback.
I did speak with my tuner (velos) and they said the stock transmission in fine up to stage 2. As well as another local tuner in Dallas.
Congrats on the car.. how many miles ya got on it ?
and to clarify, I am not calling you out or anything, I know you had posted on some other threads in regards to the tune and TCU, and had a few problems prior or such.
The issue is, there are NO REAL WORLD facts or anything that points to benefit other then "peoples feelings" thats all..
I knew someone who put octane booster in the tank and drove off, and swore it was the fastest car on planet earth because he could FEEL the power...
so, mostly when this gets brought up, more so, since some of the guys at EC were complete d!cks to people on here, it just makes it all SHADY... SHADY...
2ndly, I dont see much in what was done, that a TCU is worth it, or could amount to anything that could be benefited from, since even in the stock form, its very hard to keep the wheels from spinning , more so with a tune, etc etc..
but again, IMO, since I have yet to see any "PROOF" just heard about that unicorn a few times

However, I was able to drive my car after each flash, and after doing the CPC last. The CPC, on the newer cars 2019+, allows the car to put down maximum power & torque at any given time from my understanding. It definitely allowed the car to do a lot more, even if the extra available power results in more wheel spin (which is fun).
I had a 2k mile rally with 80 cars the day after everything was done, and the car performed flawlessly on the roads and on track. It was out pacing lots of high dollar performance cars..... I'd do the whole process again, and that is confirmed every time that I turn the car on

Cheers!

And yea, here in Boca we have every supercar, hyper car, etc etc etc , lately I have been eating all the Lambo SUV's I see, as well as some Track Cat's, and Hell Cat's .. its fun.
I am just trying to validate the TCU tune of things.. I know wheel spin is fun , but I am not into just eating tires for the hell of it, or just smoking them up just for grins. (and that can be done from Stock mode)
But I am glad your running the car it was designed to be.. I drive mine like I just got it the same day, every day, and it loves it.

Yea its pretty insane the type of cars we get here.. more so are the "kids" that daddy lets drive them, or that they bought them for...
Cant tell you how many Ferraris, Lambo's, etc I see smashed, spun out, and or just plain dumb moves..
I need to archive all the dash cam footage I have and post it ...
our transmission is the same as the old 6.2 and those clutches start slipping around 575 to 600whp but that car does not make the torque our cars make when tuned.

I have noticed a few times if I try to lug a tall gear through lower RPM in manual mode that it wants to slip... needless to say, that won't be done any more. Concerning, but also happy because it must be making significantly more power! (not having dyno'd the car before and after)
Also, the transmission in the 2020 is not the same as the last gen 6.2 car....

I def dont want to know what a bill would be like to get into clutch replacements, and transmission services from this...
Definitely do not confuse the issue that you are getting wheel spin, and clutch slippage with thinking the TCU created more power, TCU does not change power created.. just allowing it to goto the rear end..
