just wondering been searching cant seem to really find anything unless i am looking in the wrong spots but just wondering if there is a flash or anything for the 2013 e350 give it some more pop. or anything at all.
thanks

BM2BZ

just out of curiosity, are you having some problems with the car now?

blkacr05

no i havent had any issue thus far. drives smooth pulls good everything functions as it did the first day i got it. am i going to be seeing some issues?

blkacr05

just was seeing if there is anything to get some more out of it thats all. lol cant ever leave things alone lol.

yeah man same here, a month in on my 2013 e350 and im thinking of the same thing, an upgrade in the power department would be great, maybe like 35-45ish more hp nothing crazy, thus I just came out of a SS camaro that was TT pushing 940hp on the street daily. so this e350 feels a..... slow. although i love the car.

unless you have a throttle delay, a reset wouldn't do you any good.

he's talking about a performance tune, not resetting the computer or flashing a stock program back on.... altering A/F ratios, remapping the timing, removing torque management, etc.

Its probably too soon, although I'd imagine one will be forthcoming. If they can squeeze another 20 hp out of the NA 2010/2011 models they should be able to squeeze considerably more out of the turbo probably still in development though.

Without changing the engine internals, there is very little to be gained with "chipping" a naturally aspirated car. Turbos can see huge gains with "chipping" as not only the fuel maps and timing can be adjusted, but also the level of boost. If the car is driving as you say, why not just enjoy it as is? There is little you can do to that you are likely to feel.

i can deal with that just wanted to see if there is anything out there. 30 more at most would have been ok just to give it a little more pop. not that its bad now but i am sure you understand what i am talking about.

Trade it in for a used E550. Extra 100 HP and some nicer interior trim. Only problem there is that while it's as quick as a stock Camaro SS it never feels like it's going as fast as it is. I have a 2010 E550 and I frequently look at the speedometer expecting to see 60MPH and find that I'm going 85mph. The RWD camaro's feel more violent at the same speeds.

How long are you supposed to get out of those shocks on the 550, was at the dealership last week looking at one and the salesmen was trying his damndest to talk me out of even test driving one based on the shocks needing replacement every 5 years and costing 1200 each.

Not necessarily, coming out of a C63 because of space needs, we tried a 2011 E350. We only had it for a couple of months, my wife just couldn't deal with the change of power and responsiveness. So we traded "down" to a 2010 E550 rear wheel drive (air suspension be damned). She liked 550 a lot more but still complained of having to put it into sport mode to get the response she was looking for.
Some of the problem isn't horsepower, it is the "economy" and emissions programing that forces the transmission to shift into higher gears sooner and limit downshifts until you really mash the go pedal. So for Christmas I purchased her a download software package from O.E.Tuning, one of the vendors on this forum. She couldn't be happier and has mentioned several times how much it has changed the way the car feels. She says she has not used the sport button since. It's not some remarkable increase in horsepower, a lot of it is improving response to throttle inputs, seemingly the transmission included. Although I am sure paring down the ignition timing safety margin is a gain as well. I wish we had tried this on the E350 before taking such a haircut on the E350 during the trade. Consider this a testimonial, we really are that impressed the positive change in the car.

Can't you just get a sprintbooster?

C280 Sport

Trade it in for the E63.

noble idea

Interested in your post re OE Tuning performance. Need more info.

1 In the E mode I assume you still start out in 2nd gear.

2 How has that affected your mpg?

3 How did you get the download into your car?

4 How does this affect your new car warranty?

5 What was the cost?

6 Thanks.

GermanCars

Happy to relate what I know.....

1. I believe it still starts in 2nd, but I'm not sure, good question. We will confirm and get back to you on that one.

2. The mileage doesn't appear to have changed much if at all. Since the throttle isn't being pushed as hard to get the car to do what is requested, I wouldn't have expected much deterioration. She only puts about 6,000 miles a year on the car, so we really haven't had a chance to run a good long mileage check.

3. We purchased a "My Genius" O.E. Tuning hand-held programer, which was shipped to us. The programmer comes with instructions on how to log on to their website for the most up to date files for the intended application. You download the files into the programmer through your PC. All that is left is a 10 minute process to download the file into the car through the OBD2 port. The instructions are pretty good, but it helps to read them through a couple of times. And you really should have the car on a battery charger to make sure the vehicle voltage doesn't fluctuate.

4. I supposes that it is possible that a warranty issue could take place but it would be unlikely. They would have to prove whatever warranty issue you have was caused directly by the tune. I decided is was worth the very small risk as we have less than a year or warranty left on our car.

5. I would check with the different vendors as to pricing. What I paid 4 months ago may have little relevance today.

6. Your welcome, hope it helps.

A tune will not affect MPG since the car will always target a stoichiometric mixture at anything but full throttle (and warm up mode, open loop).

The C63 gets huge gains with a tune because it is intentionally detuned from Mercedes. A normally tuned and naturally aspirated engine may have 15-20 HP left in it in most cases. A gain worth the 300 or so dollars on a Chevy but maybe not so much worth the 1000 bucks on a Merc.....up to the individual.

With a car like the E350, I'd just drive it and enjoy it. Tuning it is a little like installing big exhaust on a Civic.

GermanCars

Not my experience with the E550. A HUGE improvement in throttle response, which was was our biggest complaint of both our E350 and E550. For some of us it is a big frustration to have to mash the pedal half way to the floor just to accelerate a bit when maneuvering through traffic. I wouldn't care if we didn't gain one horsepower on top, just the driveablilty improvements alone have made it worthwhile. Didn't have to pay $1000 either, although one my customers did pay closer to $2000 for a Renn-Tech tune for his E550 and feels it was worth it. And rest assured our car is fart-can free

Higgs Boson

I referenced the 350 in my post but I agree, the 550 will show more gains, especially the twin turbo version....

if all you want is more throttle response then why not just run in sport mode for free?

GermanCars

The sport mode button didn't provide the change in character that the tune does. And our 2010 e550 is sans air pumps. Again, I'm not talking about some great big horsepower change. We didn't need nor seek that. The car just responses better to small throttle inputs so much more quickly and it seems that the transmission is quicker to downshift when trying to accelerate from a steady speed. The only analogy I can come up with is the drive-line now feels more like our old E39 540i. It responses so well that you don't think about it. Mercedes' adaptive transmission logic wants to force the transmission to shift early and discourage downshifts. The tune seems to have undone some of that, or at least that is what it feels like.
I don't know what it would have done for the 2011 E350, but I wish I had tried it before going back a year with the 2010 E550.

Higgs Boson

a tune removes torque management, or some of it at least, in all it's various forms. in these cars the driver does not control the throttle with his foot, only sends a torque request signal to the ecu......the computer does the rest. a tune reprograms what the computer does for any given torque request, in a nutshell.
