127 trap speeds are good, definitely should be getting better than 11.5 ET
did you try any runs without brake torque just to compare?
how exactly are you launching it?
you should be low 11 or high 10s
ive been wondering how much time may be lost with mash and go vs brake boost launch.

Launching at around 2100 rpms, which may be a bit low. I'm either too low or the ECU freaks if I go much higher than that. Need to find that sweet spot.

I have the same tune and can confirm its got really aggressive power delivery.
i don't think it will ever hit 10.7. I think 10.9-11.0 is more likely on this tune. Still very good.

Tried runs using brake torque and RS. Didn't do mash and go this time. Best run was using Race start this time, but it did bog. I've found that if you launch the car using Race start and launch it as the rpms rise it won't bog near as much, but messed up on this run, and didn't catch it at right time.

i think with this you will get low 11s

Will give that a shot. Would be awesome to see something low 11s.

It's not, it's one of my cars that's not a MB, but my point was, if he can pull a 1.6, with a 127 trap, he'd be in the 10's.
His car is booking it on the back 1/8 and making some time. Tweak that 60' and he'll be there.

So so with this car because of the torque limits in first few gears you end up with a trap speed that is usually higher than what it should be for the ET it does...
definitely the absolutle most annoying thing about this car, I hate that it does this ****.

the only problem is the torque limitations in first gear are preventing that 60ft from being as low as it needs to be for solid consistent 10s.

Still can't get below 11.5 ET, but with new tune getting consistent 127mph traps, compared to consistent 124mph traps (with one 126 trap). All with mix of 93 and 100 octane fuel.
Had new motor mounts and trans mounts installed, as mine were shot at 30K miles.
Still working on launching this thing to get my 60 ft down a bit. Haven't been able to find the sweet spot just yet.
There was a beautiful stock c63s sedan that ran 12.0x at 120. Was his first run in the car. Probably into 11s after he ran a couple of times.

Does the EC tune give more power with that or is it tuned for max power on only 93 octane fuel?

If I attempted to answer that question, it would be pure speculation. When I sent my ECU in I noted I run 93 octane on street and 100 for track. Getting custom dyno tune Saturday; will report back then.

You might have mentioned this, but what tires are you running? My 2014 CLS63 with renntech tune and new spark plugs ran 11.2 while running PSS. I threw on Toyo R888's for another run and dropped to 11.1. Maybe try a stickier tire?

Running Pzeros presently. May try to find some stickier rubber when these are done, which I'm sure will be soon. Thx!

EC told me they only increased torque output between stg1 and stg 2 because turbos on stg1 already maxed out on horsepower (about 600-610whp without DPs). Now i do wonder if using 100 octane vs 93 on this tune will give a bit more power.
They said if i were to do a custom tune it likely wont make much more than the stg 2 as its already maxing the engine potential safely.
I think between custom tune and 100 octane you can squeeze more out.

Will be interesting to see if your custom dyno tune will yield any more power than the stage 2 EC tune.
