AMS should be around ~630 on pump gas. ~700 on 100+ octane. Regardless, this tune is showing great results!
Savage hey bud hows your ride!! thought the ams tune at 630whp was tune on 93 fuel but also required downpipes. I'm just super impressed that EC figured out how to achieve HP/TW numbers of 650+ on just E50/E85 stuff and moderate boost increase to 15-18psi which is probably safer for the turbo
Doesn't explain why magazines were doing 11.6-11.9, albeit with a slower trap.
non-prepped surface and 41 degrees outside are likely culprits, as well. the trap speed shows that the power is there. the ET is more related to traction...

Mines RWD I was doing that on a road with a slight curve it was also dark and cold.
The car spins the rear wheels, I'm looking to get a set of Toyo r888r or the MT ET street tyres. I've just bought some more Alloy wheels for the rear just need to get the tyres and wait for warmer dry weather and a decent straight flat road.
Why isn't Eurocharged making their own thread on this? @loungn14 Are they waiting until some other features/testing is complete, or until they have a whole e85 upgrade kit, or what? Based on what people have stated, they are selling the e85 tunes already if people ask them for it.
Did you do OEM mounts? I heard it's $$$$ to replace engine and trans mounts.
Savage hey.. had my trans and motor mounts replaced last year at 28k miles under original warranty. thats on a stock 15 E63 which isnt my daily driver so i think the torque in these cars accelerates the wear of the motor mounts big time!

I replaced then with stock mounts once again. The drivers side mount was shot, as was the transmission mount. I don't remember what I paid, but I think it was in the 1500 range. It was at my local AMG speed shop, not the stealership.
Update was waiting on the dragy(received) but cant upload videos thought. Its captured on the dragy app but no way to share or export it. I'm on Android and I read where they haven't made it compatible yet. I can see the overlay on the dragy app but the video that is captured by my phone doesn't have the data. Need to figure that out shortly as I want to hit the track in Sacramento soon. Have one verified run but we all know that isn't good enough I want several 0-60,and 1/4 mile runs which I haven't been able to do yet.60 to 130 would be nice also. Believe me I have tried need a dead time during the mid day or late at night.
Dyno completed today we logged the best 2 runs almost identical the 1st run was 10HP/10TQ below the current numbers. Once I have wasted a full gas tank this coming weekend I will order the Brutus (E50 tune) come Monday then redyno for comparison sake. Not bad for a stock E63S (only Renntech exhaust and 2nd cat deletes) Then its the TCU (Rennech) I will have to ask for advice for the HPtuners software modules so I can capture the necessary data. I will explore as much options as possible and provide as much transparent information that I have and that will be asked.
Its a little blury but the bottom middle section shows the 2 runs side by side.
I will be posting a ton more of these give me until Sunday evening.
This is like Christmas for me. Lol.
Are you able to share your runs to the draggy site? What's your name on draggy so I can follow you.
I'm brutus_tx on draggy.
Merry X-mas then LOL. I am going to use the same name (Marine 1) but let me get some decent runs in the next couple of days then I'll upload all of them,.
What is your current expertise on HP tuners software I need to pick it up and start data logging. I want to be at a novice level before the TCU is flashed.
Also The tuner has pulled for his own import cars E85 across several Northern California cities (close proximity to me which is good to hear) and the least amount of content for E85 was E81.
So in essence close to 102-103 octane reading. I'm going to get a sensor and have it relayed via Bluetooth functionality. I need will then to increase or decrease the gasoline mixture. I plan on running E50-E53 all year long. Not sure where this will lead and how far I'm going to push the envelope but for me a High flow fuel pump and lines for full E85 sure does sounds enticing to extract that much more HP/TQ along side the TCU should cataplut this sucker into the mid 10's easily..
5soko is your go to guy for all things HP Tuner.
Between the two of us we'll get you sorted.
There is a web based data viewer which is very easy to use that helps make sense of all the data as well. 5soko can hook you up there as well.
In HP tuners, you can open your log, or if you have finished a log and saved it, click file > export file > click export.
now you have a datalog file that is saved and ready in .csv format.
visit Datazap.me, like Brutus mentioned, free viewer, which will graph your .csv file datalog with all your paraneters quick and easy!
make an account, upload your .csv file and your ready to view the datalog in graph format. Click any parameter under the graph to showcase it. Best viewed on a desktop so you can run ur mouse over the graph and values.
Thx for the info @ Brutus_TX and 5Soko I'm pretty savvy on software applications once I get acquainted. I still might reach out for exacts to help facilitate the information and data.
Hope to capture as many 60ft's as possible in the next few days for base line performance before I flash via E50.( next week). The reasoning behind this is for complete transparency for the TCU update and the exact parameters and performance that this will bring once I drop $2480.00. Is it truly worth it and how many Tenths will I actually pick up. I don't want to leave any doubts on the table for the full audience here as I will track and log all data. I might start to chime in the TQ limits thread once I datalog and capture all of my runs from stock to E50 then TCU update.
5Soko I saw the reply with the torque limits in the 1st 2 gears: 1 piece to the puzzle..
TCU limits set by AMG: 1st gear TQ limit: 650nm/ 480 FT LBS (@ the engine) 2nd gear TQ limit: 750nm/ 553 FT LBS
My question is what can they (internal parts) handle in each gear safely? The question I will have for Renntech what are the tq settings raised to on each gear setting and throughout.
Thx

I had the RennTech TCU, likley .10 tenths is all you could expect to gain. At least in my application on the street, it made it harder to launch the car and I broke the transmission. So there is that too. Due to the nature of "modified" cars and the variables in play, it's not possible to say for sure what was the root issue. However the TCU proved to be harsher on the driveline then stock as one could expect. Nor was the TCU a "game changer" in fact my best 1/4 via dragy was on the stock TCU.

Yikes! Yea, it's this exact scenario that makes me think that it's not wise to mess with the TCU.

All the tcu tunes on the market aren't exactly tunes really, more of just raising limits or removing some limits, they are all doing the same thing, just either to their personal settings or the customers.
I dont know the exact number off hand as to where Renntech raises the tq limiters but i do know a few other companies are raising it by around anywhere 70ft lbs and other to 100 ft lbs. in 1st and 2nd.. According to a few guys I've talked to out in Europe, this seems like safe zone they all are liking to be out for the standard tuner customer.
If you do talk to renntech with the exact numbers post them here so we can collect more data.
I dont want to get off topic here but we can continue this in the TCU thread.
IMO if the general consensus was overwhelming in the data to support the theory that a TCU flash is directly correlated to transmission failure then I would cease to follow this path.
But reading through the comments only a single person state side has come forward without root cause analysis. Some people's reaction is immediately "hey that is a know issue" I will seek to prove other wise.
The next line of questioning is asking Rennetech and Gad Motorsports how many TCU flash's have they done? (Hopefully they can be transparent as this will benefit them in the long run)
How many clients have built the transmission to support the upgrade versus just flashing?
The final question is based on the above criteria- how many know failures have been recorded versus non failure then we can calculate percentage's.
This route for me is based solely on empirical data not conjecture or superstition. Not saying there isn't failure I just need to validate the the hypothesis.
Thx for chiming in and offering your opinion.
Next step for me is the E50 tune ordering this coming week, record improvements until I have satisfactory results then the TCU. In the near future I will elect for Exedy clutches as I might push the envelope further than just stock equipment.

definitley sounds like the TCU tune broke it, and the sad thing is that you were even faster without it.
even at best, if raising those limiters are only going to give an Improvement of 0.1s from 0-60 (first 2 gears), and comes at the cost of transmission reliability it doesn’t make sense to do it, period. Better off focusing on making a bit more power on top end (3rd- and all of 4th gear which has NO limiters) to propel car in 10s than trying to do it this way.
the only other way I can see a TCU tune being ok is if you get supporting hardware with it, maybe just upgraded clutches are what’s needed? Then you need to consider the cost vs benefit ratio here which is again not looking favourable
Saw this on *********. From the comments this company is know for Mopar crowd but has since made the move to MB.
This looks very promising for a transmission upgrade plus a TCU tune. I haven't read to much chatter on this but its worth the time and possible investment.

The main roadblock for modern Mercedes-AMG's seemed to be the TCU (transmission control unit) software. It seems tuners are able to address the TCU now on the 722.9 MCT transmission which means upgraded hardware to pair with the software is key.
Southern Hotrod has the hardware for the 7-speed 722.9 MCT. ********* is not familiar with this company but ********* users report some successful results in W205 C63 applications.

Am i missing something here? Brutus you are saying this is a flex fuel tune? do you know what flex fuel means? Is there an ethanol sensor you are installing? How is the vehicle adjusting for the E content? E85 does not mean flex fuel. There is not a flex fuel kit on the market anywhere for direct injection engines.
Unless im totally missing something here you have an E85 tune. NOT a FLEX fuel system, they are 2 very different things.
