I'm well impressed, naturally I want more but that's my nature haha
1st & 2nd in anything other than super dry conditions is hopeless to be honest. 3rd & 4th much better but I still get wheel spin in 3rd to 4th and sometimes from 4th to 5th. It's a beast on the road it really is it pulls so hard in 3rd and 4th. It hits about 135mph in 4th before changing to 5th.
The tuner has never had anything in the Dyno that powerful his face said it all when he was sat in the car and the front was lifting. I'll try and upload some videos if I can.
I took him out in it after and he was creaming his pants!
Still going to see if I can get on this other Dyno and get some more runs and data logs.
I've ordered the dragy GPS so will also see what times I get 60-130mph as I don't have a 1/4 mile track.
That's awesome. Looking forward to some videos and some draggy runs. For me, the proof is in the quarter mile trap speeds. If the car is truly making power it will be reflected in the trap speeds. This eliminates the "what dyno was it on" argument.
Find a quiet stretch of level road in an un-populated area and give it a go to log the quarter mile. Your times may be sub-optimal when compared to a prepped surface at a quarter mile strip, but your trap speed should be pretty close.
Yes I'm a newbie but not to the Mercedes world, so forgive me for chiming in earlier just elated on the progress here. I just picked up my other baby. Long story short it already has secondary cat deletes and a Renntech exhaust. Sounds mean even in C mode. The dealer said it a renntech tune but subsequently it has been flashed back to stock. Nonetheless I have been following all threads from here and read every single comment (seriously). I will be dyno'g the car next week in its form now then following up the the flex fuel E50 route. I am really intent on adding BMC or AFE dry filters and DP's. Emailed Jerry he stated he has a set of used Renntech catted DP's on his car and they added no power so that might be up in the air. So to continue the research here I will baseline and follow up with the progress throughout my adventures.
Wish me luck and welcome to the W212 platform. I will also be investing in data collection which should help here.

Historically Tuners call any tune that works with stock hardware as a Stage 1 tune. Stage 2 is reserved for tunes that require some modifications to the hardware to perform safely.
Seb's tune should ideally have been posted in the Stage 1 tune thread to avoid confusion.
Both my tune and Sid's tune are considered Stage 1, as they both work with the stock hardware.
When comparing my tune to Sid's its better to consider my tune a Stage 1+, as mine uses upwards of 18 psi boost to his 14/15 psi.
Sid makes less torque than me because his tune makes less boost, but he is also able to run full E85, whereas mine, being more aggressive, is only able to accept up to E50 in the tank. I am fuel pump limited.
If our respective dynos can be trusted then Sid is making almost as much power as me, but maybe 140 lb-ft torque less peak torque.
I wish Sid was in Texas... It'd be great to line them both up to see what difference there is in performance. I suspect I'd be ahead in a drag race from a start, but from a roll I expect they would be much closer.
There was a comment about down pipes not showing power with this tune (or maybe in general). Where are the fuel limits reached with stock fueling on this tune? Additional power is usually more airflow & more fuel required. Would it make sense that with stock fueling limitations, that no mods except for the tune is equal to any other combination of mods with the tune?
The question of DP's was attributed by Jerry when I asked him if there are worth the investment he said they showed no power increase in his current setup. That answer just saved me a few thousand dollars that I will invest in other means towards the car. I also asked him about the filters I might run he said he has stock filters.
This just shows the amount of propaganda fluent in the aftermarket world to attract clients. Brutus_tx made this claim earlier when a friend of his dropped 25K to run a 1/10 of a second faster at 2 miles per less trap speed. So shout out for someone to challenge the status quo.
That question about fuel requirements and the flow was asked earlier and I think brutus_tx was going to try and collect that data.
I'm pretty sure support modes will help to push the E50 flex tune to greater levels. My next stop after my before and after tune is to invest in the TCU setup and display the data.

I'm excited to see someone else investing in the data logging tools necessary to really quantify these tunes! Kudos to you Marine 1! I'm keen to see your results.
I wasn't able to discern what the max flow rates were for the injectors,but then again I didn't dig all that deep.
This is my daily and I'm waffling on whether to get the TCU tune or not. I have an opportunity to get the Renntech TCU Tune but I haven't pulled the trigger yet.
My goal was 10's tune only and I'm agonizingly close to that milestone. We are going back to the track on the 17th and I will drive there on E50 and put a splash of GT Plus Race Gas on top see if I can crack the 10's barrier.
It's possible that down pipes would have gotten me there already, but I didn't want to rely on the aftermarket for the performance. If you are willing to do the investment needed to push the performance envelop then I applaud you!
Personally, I am really struggling with the justification of aftermarket hardware to support a tune now that I've had my tune for a few months with over 3000 miles of aggressive driving on a stock platform. I've seen the effects that throwing the check book at a car has gotten my friends. I'm more than skeptical that additional hardware is required when you have a competent tune.
Yes sir just extending the same courtesy you have provided for the community here. Well done..
Step one- Base performance
Step two-Eurocharge flash (E50) it should read the Brutus tune.
Step 2.5 Dragy app (ordered already and plan to use as a base measurement)
Step 3 -TCU- Renntech tune which I do feel a bit more comfortable since the TQ management is "controlled"
Step 4 Data logging and feedback.
Hi, I have a 2012 CLS63 with E85 (100%) stage 1. Limited to 640hp (740lb.ft) due to the fuel pump not delivering enough fuel. Do you know an upgraded fuel pump to replace the original one?

Where did you get that tune from? I've been searching high and low for an uprated fuel pump but I don't think there is.
Im not sure where Jerry from EC got his from or how he's done it.
Once you upgrade your high pressure fuel pump I would also look into larger diameter fuel lines, an ethanol content sensor, Then have Jerry work his magic and reflash since you will have the supporting modes to really have similar numbers to his. Reading online it looks like after time some of the rubber fittings along the fuel system might be subject to getting worn out prematurely. You can also ask Jerry for his advice.

Thx hope to see those revised dyno numbers soon.
Glad to see see people coming up to speed on the minimum requirement to run a true E85 tune. You can also keep the rubber fittings lubricated and prevent premature failure by running 91/93 every few tanks or run an E50 blend for daily use if your tuner can develop a true flex fuel map.
The fuel pump and bigger lines sounds like a good idea, but why the ethanol content sensor? If I have a flex fuel tune then it doesn't matter what I run?
My dragy has turned up will give it ago later on once kids are in bed.

oooohhhhhh! Someones going to be misbehaving in France... standing by for results!
Have you registered with draggy yet, and if so, whats your handle? I'm Brutus_Tx if you want to look back on any of my runs/videos, from Stock all the way to my present tune.
Please upload any videos if you can.
I use this mount for my iphone... it works a treat.

If it’s a true flex fuel tune that can properly manage anything from 91 to E85 you technically don’t need a sensor but why not spend the extra $150 when you’re probably $1k already for the fuel pumps and fuel lines? Why wouldn’t you want to know if you’re getting crap E30 or real deal E85? I’d certainly want to know one of the variables that can dramatically affect performance!
I've not got a phone mount like that just a vent one. I'll get one though for sure!
Yes I registered awhile ago and didn't realise you need the little box you stick to the dash haha. My handle is Eddietemple69.
I've realised the problems on the dyno.on Friday were because it wasn't in Dyno mode haha 🤦 tomorrow will be interesting now!
To utilize the video recording capabilities of the draggy, you'll need a mount similar to this, as the phone's camera is used to video the run, with the software automatically overlaying the data.
Here's an example of what I mean from previously when we were still fine tuning the car.
