Naturally this tune is available for any M278 (4.7 L V8 Twin-Turbo). Applications are in any Mercedes ending in 550. Example E550, ML550, etc.

So wonderful to see someone finally did a detail dyno analysis of the M278 ECU HHT tune, drag racing w/ AMG and post-tuning driving experience and pull data. THX!!!

Yup! The whole shooting match! Glad you like the videos. :)
Insightful video! I especially appreciate the added technical explanation with the dyno graph and data logs. Running into the man himself, great way to end!

Amazing and detailed. Thanks for putting in all this work for the car and us!

Thank you! I agree. 4 cyl Hybri C63?? Nope!
I love the intro 🤣❤
Interesting info on the tune. Had no clue.
I have one main concern about this tune, I 100% agree is one of the best if not the best, BUT.. how is the stock transmission handling that extra stress? Is it ok on the long run? Do you need to reinforce it? Please let us know.
Awesome job. I used to have the Renntech tune on my CLS 550, it was fun to drive 😊.

All cylinder walls ok? Many people have scorings on m278…

I've had no reason to have my cylinders scoped (eg: pining, loss of compression) so I haven't had that procedure done. @@fb8207

@@clevelandaeromotive knowing many people who drive a 278 and have not issues. But after scoping the cylinders there a lot of scorings. A few with 80-130tkm on it with normal driving and the good 102 aral ultimate from germany… others drive 300tkm and have no scorings…
that gold wagon rs60 is one of only a handful. sienfeld has one of the other 5 sedan though. i believe that and the early sec amg belong to the MB market guy blakely. he is a big help to the premerger scene. thanks so much for showing this to us!!

Awesome vids. Thanks for sharing. Where did you get your front splitter for your CLS? I have an s550 m278 and I'm looking to put a splitter on mine.

Nice video, I assume you’ll do a driver’s review of how the car has improved?
@clevelandaeromotive

Yup. That’s my video from a month ago. The one with the “Zero to 60 Time” thumbnail.
Whats up brother. Nice car. I have a 2013 s550 thinking of getting the tune. I was just wondering if u think it will cause the car to have problems . Will the differential ands trans hold up ?

A car with a tune will hold up as well as you treat it. Can you go out and blow your engine with a RENNtech ECU tune?? Just as easily as you can with a stock tune. If your out there treating your car like poop, constantly racing it, neglecting it, expect engine trouble. If you maintain and care for your car well, a RENNtech ECU tune will take no more miles off your car than a stock tune.
That front lip. Where from? Fits perfectly

look at those recaro cse's!!!!
How much throttle can a stock 550 handle? Ive been going easy and never fully floored mine yet its over 100k so what would you say. Its been well maintained. Im 3rd owner

With the RENNtech ECU tune, at the Bradenton Raceway, I floored it off the line all four times. Although admittedly, I always roll on the power from a stand still in day-to-day traffic. So, in all reality, I really don't know. I think the stock ECU on a CLS 550 really cant harm the car's power train.
Where did you get the front bumper lip?

Even an 80’s 420/500/560 sel would be cool with an LS swap
It would be awesome if we can race some day to compare my tune to yours my cls 550 is tune by weistec

I've heard good things about Weistec as well. Enjoy!
Anyone know how much power the m278 can handle reliably?

Considering the block walls are thick enough to be bored out to 5.5 litres for the AMG’s M157… a LOT more than any Mercedes Benz factory application places on the M278. It’s well known as an “over-built” engine. Anyone else?
