Do you have a TCU tune?

I have this same TCU tune from "demetre" it does wake the car up. I like it as I have this TCU and kept the stock if I wanted to swap back easily.
Tony set the ECU to 7000RPM as I think some had issues in S mode with the ECU and TCU fighting each other up high. I've not had any issues.

7100 RPM s ? ,on 55 motor ,
I have a Kleemann TCU tune ,RPM is a little higher then stock ,not much ,no where near that,
Been trying to get rid of a fuel cut 1-2 shift when roll racing ,totally annoying,instant 1/2 a car loss lol,at the track with a dead hook no problems .
It's not really hitting rev limiter so to speak,I think the tires break free and motor accelerates up real fast and either TCU or ECU see a problem and cuts fuel till the shift ,then it's full on again ,yes it does it in all Trans settings ,S,M,W and with old TCU ,
Maybe load vs rpms vs who knows what lol
I think one of the computers sees a really fast climb in rpm and anticipates a prob so it cuts fuel till shift, even though I have a TCU tune it may simply be an increase in the RPM s ,that's why it happens with both TCU s ,
Anyone ?

Stock motor and stock pulleys with maximum cooling and breathability mods. I've ran it hard at 7100RMP all day. I will say I generally drive in M mode and nets a lower than redline shift. It will peg the 7K red line in S mode. The tuner said it was safe... I trust him more than myself

Isn't this same trans that is used in the v12's which have more torque and the torque peak is at 1800rpm? So the peak torque is hit more often/handles the additional stress more often and with ease?
#32
And I don't believe the higher shift points are going to be harder on the transmission at all. The torque and hp is actually falling off faster at those rpms. What kills these transmissions is excessive heat of the fluid and when modifying the Trans in an undesirable way such as shifting with to much line pressure. I wouldn't say there's any data to show the dot 6s dying due to raising the shift points.
Not to mention the the obvious failures of the dot 6s with drag radials and a number of 1/4 mile passes. I've smoked a few dot 6s in different e55s I've had over the years, once built like the v12s I've never had an issue in any of the ones I've built. Also adding an additional Trans cooler works wonders on the stock set Trans cars.

Problem with Demetres TCU tune is indeed the ECU rev limiter thats hit in S-Mode, as the full-throttle shift points are higher than stock and most tuned ECUs rev-limiter. I like that the M-Mode will now hit the limiter everytime if you are not quick enough with pressing the shifter/buttons/pedals and the removed torque management. However the S-Mode stuff holds many people back i heard.
If he would be able to lower the full-throttle/kickdown shiftpoints so it would not hit stock or normal tuned ECU rev-limiters, it would be great. I think his TCU tunes are based on Weistec, yes.
I wonder what happened to Eurocharged TCU tunes? I remember last year as BIP was still active, BIP sold a Eurocharged-made TCU tune that was also kind of "agressive" and people loved it, while the normal sold Eurocharged TCU tune was kind of "boring" to most people i read and some did not even notice any big difference to a fully stock TCU.
Jerry told me once via email that they can alter like 140+ values in the TCU to whatever liking of the customer. However i personally assume that most TCU customers just orderd some sort of "mild-tuned/stock" variant of their TCU tune, by well... just ordering it without any further comments/wishes.

I have been on a Eurocharged TCU for about 2 years, I also had one of Demetres V1 "Weistec" tunes with the 7000rpm limiter - IF you did not get the ecu limiter raised it would fall on its face at WOT shifts (I had a 0.7 second slower time at the track with the 7k tcu vs the EC tcu without my limiter raised), this WOT issue however was resolved by getting the ecu limiter raised.
I did not like the original 7000rpm tune because lets face it, we don't have flat plane cranks and the engines are not setup for ultra high rpm
I am now however testing out his V2 tune - 6700rpm limited (still a long way away from an in depth review) but so far it is exactly like others have mentioned except with a more realistic shift rpm
The car feels 1000lbs lighter and more "ready to go"
Moderate throttle shifts are snappy and the car is as if I am in race mode 99.9% of the time
Daily cruising and light throttle is as smooth as stock
It just feels ready to go anytime
Wheel-spin also seems much more apparent from higher speeds but too many variables right now to quote on that
Compared to the EC tune I was running it is night and day more aggressive and completely noticeable, whereas the EC tune had me questioning if it was money well spent and was a more "relaxed" tune overall
* Anthony Lawshee ex BIP / now Race IQ Performance is also another one who offers some great aggressive TCU tunes who can help you out

I trapped my highest mph with eurocharged tcu tune with stock shift points, my traction issue is a different story but, I feel the stock shift points works good for my car.

where do you get this v2 tune from?

I've had the EC TCU tune for about 6 months and so far so good. Smooth during regular driving, no difference then before, but certainly feel more torque when you lay into it. I'd say worth the $.
It actually surprised me the first time i got on it after the install. Literally spun the tires at 40mph on a dry sunny day, and that's never happened before.

A number of members here have been using with great results this: https://mkultra-electronics.company.site/ Member @zerocat101 here is the owner of the tuner. Here's one thread discussing the TCU: https://mbworld.org/forums/w211-amg/...hatters-7.html

I'll say that if your car is all modded out and you have drag times in your signature, you will probably be amazed with the tune. If you have a stock car and just want the transmission not to take 20 minutes to shift gears, then there are some things about the tune that you may not like.
I think I'd be happy if there was a version that kept all of the latest OS programming and TCC control stuff, BUT kept shift points close to stock. For me, I find the shift points too aggressive. I can go into more detail but I wanted to at least mention that much. Unfortunately I think I am in the minority on that. You either want the car on full kill, or you are happy enough with the stock TCU. I am in neither of those categories.
Other than that I doubt anyone has taken the TCU nearly as far as Troy has.

Gotcha.....ok I follow you now. My Ford Expedition does what your saying when the tune is loaded in. Shifts WAY too late for granny style driving but if you were to just drive it hard then it would not matter. So now I only use the tune when towing.

Everyone has mentioned the faster up-shifting but how are the downshifts? With a built transmission and the upgraded valvebody the downshifts while coming to a stop are pretty harsh. Think downshifting a manual and not rev-matching. Needless to say this can (and has) upset the rear of the car coming into corners during "spirited' driving (not as bad when driving in manual mode).
Does the transmission tune help with this scenario at all?
