Spending the last 2 days emailing back and forth ecu tuning companies (4). They all say that "new ECU's cannot be flashed through the OBD2 port like the rest of the MB cars." ( word for word from 1 company) I am thinking about going to the closest location for a highly respectable company which is in Boston. 5 hour drive one way. What do you guys think?

I would prefer someplace local like a oe tuning dealer 20 minutes away from my house but nope got to bench tune the ecu i wish i lived near a major company's headquarters

Try searching Kleemann in your area if you have not done so

I tried emailing the dealers in my area (50 mile radius lol). All of them says "gotta ship ecu to my tuner"

well im going to continue my search. Emailing every tuner in the tri state area lol

jimmy k

Im sure you will find someone, I guess you do not want to ship it out for some reason ?

This is sad to hear. I was part of a Toronto group buy but turns out, like you said, the 2013 models need to be shipped.

What are the companies telling you for power gains?

xjaymzzx

Its my only car. If i send out my ecu i got nothing.


Lol i have too much but most popular companies are oe tuning - 8 whp and eurocharged - 28 whp.

You can thank mercedes for this problem. They just keep on making it more and more difficult to mod. They don't want us to f**k with their s**t.

There is NO company that can tune our cars through the OBD port. It's locked period. I suggest you make that trip and at least you can have it done the same day while you are there to watch them. Otherwise get a tuning box (btw, Kleeman is also a tuning box) which seems to be the direction we are headed with the way manufacturers are programming their ECU's.

Problem is kleeman is $1000 and up. I Have a hard time justifying that. Eurocharged is a great alternative if you can get to them.

Do any manufacturers offer tuning boxes for the M276? What is the advantage of using one? Do they act as an intermediate between the ECU/TCU and the engine?

Knightmare69

I can't answer the first part but the advantage so to speak is that a box is easily removed and isn't as integrated as a flash tune, however that's also a disadvantage, it's not that integrated so you're not getting a real tune.

Tuning boxes are an evolved form of piggybacks, using microprocessors they intercept and modify signals sent to various parts of the engine in order to obtain power. Some companies multiple points in the engine while others less.

For 276: True (a the time of this writing)
For 272: False (look at OE tuning)

I also looked into Kleeman, and the "dealers" simply ship your ECU to Kleeman's US headquarters in CO.

I've been patiently waiting for OE Tuning myself to come out with a compatible hand held tuner.

Which engine is the 272 again? Not the CGI correct? those are 271 evo?

JaredP

The 272 is the N/A non-direct inject engine found in the pre-facelift W204s and the 2012 C300. 276 is the gasoline direct inject engine found in the 2012 C350, and 2013 C300/350.
