Eurocharged TCU Upgrade
I know that it speeds up the shifts, changes the torque limiters and changes the redline but does it change the, Comfort, Sport and Manual settings and how?
Thanks

The car is overall more drivable with the TCU tune. The slippage has been greatly reduced. Driving around town is much more smooth because the shifts are more direct now. This TCU upgrade was a great mod. I did a couple pulls tonight in auto s mode and was blown away at how high she revved. 7000rpm FTW!

Can we order the TCU upgrade with stock shift points and just raise the line pressures, shift firmness and other attributes. Unless raising the shift points to 7K is proven to increase 0-60 and 1/4 mile times, I'd rather stay with the stock shift points. At what RPM does power start tapering off with this motor?

What I don't get with this "power dropping off argument" is the SLR. She is no thin mint and pulls mid 11s stock. With driver, it's easily 4000lbs (3858 curb) and shifts at 7000 rpm. While the SLR engine is different, it's not totally different ya know. She has more aggressive cams and heads tweaked (not radically believe me) but so do a lot of guys on this forum. Supercharger is tweaked up but again so are a lot of guys on the forum.
Just saying why would Benz crank up the rpm redline to 7K if they didn't see power in that extra 500-800rpm??
I kinda come to the ultra shade tree mechanic's opinion that it is a bit taxing on our engines (and why would you want to risk it on a 4 door dd in AMG's mind) so use at your own risk....but I believe there is power in them there r's.

I did calculations in another topic and the car most definitely should be quicker if revved to 7K and there should be no side effects in doing so. It doesn't go that high bone stock because bone stock it doesn't need it but modded is a different.

Shouldn't things like valve springs and lifters come into question possibly? I'm with the other guy with wanting to know when the valves start to float. I'd bet the valvetrain is different on the SLR. Were springs stiffer? Lighter valves? Cam duration, lift, or split different? Different lifters? How strong are those connecting rod bolts?
I'd wonder about stuff like that before zinging a VERY expensive motor past factory redline. Adding a bigger pulley and headers for more airflow and power doesn't mean the valvetrain will hold up and not drop a valve, or shoot a rod through the $10,000 block.
Not saying its not safe, but just assuming it is because you have the airflow to support it is a bad idea. Never heard anything about valvetrain mods in the couple months I've been on this board. Maybe I've missed something?

SLR curve is very smooth on the dyno (even a modded one) and the fuel system is diffrent, maybe thats why it shows power up to 7000 RPM, don't forget the cooling and large intake it has + larger TB that allows alot of air to go inside @ high RPMs.
![nix](https://mbworld.org/forums/images/smilies/nixweiss.gif)
this one had pulley + intake filter and on 91 Gas. and you can see the TEMP was 39.8C = 103F
this was tuned by Jeremy from OE Tuning.

we did another one that reached 670rwhp with more mods and on 93 GAS, same weather condition almost.

BTW- Eurocharged already adds a 6,700rpm redline to their ECU tune if you want it.

Interesting dyno of SLR. Torque obviously drops off up top but hp stays nice and steady on up to when she prepares to shift at around 6800.
No idea what that means of course, but very interesting how hp stays up there and doesn't drop off the face of the earth til after 6800.

RE: TCU
I've had an early version EC TCU in my SL for a while, very happy with it.
Anticipating the day that EC brings us a TCU upgrade for the 7 speed, if anyone is listening.

While I basically agree with that, the stories of people with pistons cracking (pretty much proabbly not at all related to RPM) is a sign to me that certain criteria may be being pushed a lil too far past the margin of safety I would like to keep. I'd rather give up a tiny bit of performance to not risk catastrophic failure. I guess I'm just getting old as before I'd say run it for all its worth and if it blows I'll build it better next time. lol

Broken rings lands is due to the motor going lean, get the TTM fuel rail and injectors and that problem goes away

The one thing I will say being that this is a combustion engine.
The red line is the red line like a stop light it's not meant to be passed and when you do you take the risk.
I guess that I'm old school when we were taught that the red line is not a shift light. You avoid going there.
Tuners chime in and educate me please I'm willing to learn.
