Hello! I have an 2011 e350 4matic sport sedan. I was thinking about getting the OE tune for this car today. Any suggestions or things I should know before buying? Much appreciated.

KEY08

What does a tune do for the v6?

Anthony Harper

to be honest I’m not looking for speed or anything. I just notice I need or hope to get a better throttle response. When I hit the gas I notice my car takes a little time to start moving but as for what it does not much that I know of. Just looking to make the car more responsive... that’s what my hopes are with a tune.

KEY08

Maybe look into the pedal commander for your model. They are on sale. It will increase your pedal response and avoids the expense of a tune on an engine that you won't notice much when tuned.

huh, when driving in slow-n-go traffic kinda conditions, I wish the low end of the throttle on my E350 was a little more progressive, less aggressive.

I'm sending my ECU to these guys:

https://www.kleemann.dk/kleemann-usa/

I inquired and they responded here:

"Our ECU tune for your 2013 E350 sells for $1295.00 and will take power from 302 to about 325-330 on USA pump fuel. We also revise throttle mapping and remove the top speed limiter. The ECU must be removed and sent to our USA HQ for programming and I can typically get the ECU turned around the same day it arrives, as long as it comes in before noon local time.

If you have any other questions or concerns, don’t hesitate to let me know.

Thanks again!

I agree. I had a "Sprint Booster" (same idea as pedal commander) on my C300. It really helped with throttle response. It doesn't make your car any faster, but it is more enjoyable to drive.

I'd love to see before and after dyno runs on the car.

Senecan

Me too... Stay, "tuned"

You’re spending over a thousand dollars for an extra 20 horsepower on an e350? Why?

Senecan

Well I quit smoking crack, so I can afford it now.

alan_e550

I honestly think drugs are a better investment. You could buy a tune from OETuning for less than half the price. I payed $460 for both the handheld tuner and the tune itself for my e550

Senecan

Must be inflation, cuz they want $900 for that now.

I did get it on a sale during the holidays however that still saves you a considerable amount of money and the pain of having your ecu shipped. I hope you are satisfied with the work Kleemann does on it, however thats an absurd price to pay for 20hp

Senecan

I'm sea level. My money is on closer to 30/30 wheel. I'll have before and after numbers by this summer.

making the throttle more aggressive is mostly a lost cause;. you make the car harder to drive without any real resuilts.

Dane500

Easy fix. Buy a 550.
try resetting the TCU/ECU and see if that helps.

LILBENZ230

Same. Coming from a number of older-but-recent Benzes, the 2016 W212 throttle is really aggressive. Surprisingly so when the throttles of the older models were so, so numb.

Pretty sure Vladimir told me he could tune the M276 to 322hp/296tq for significantly less than $1295 but I don't really remember now.

probably, I am a 66 yr old retired computer engineer... I just don't like cars that lurch forward under very gentle throttle. if I want to go fast, I am happy to give them more pedal.

LILBENZ230

I'm 35 and I agree with you. My E350 can be quite jumpy and it is probably my least favorite thing about the car. People I let drive it the first time, or people who don't drive it regularly, often can't start smoothly at first. It's got the throttle tuning of a 115hp econobox, really. You know the ones. The first 25% of the throttle gives 75% of the power so you think "Well this isn't so bad". But with 300hp it's just unnecessary. It also does not help with the eco stop/start system.. I actually keep that enabled and have adjusted to a method. If I'm sitting still with brake hold engaged and the engine is off, I tap/release the gas pedal quickly to restart the engine and then ease off the line. Just stepping on the gas will cause the engine to fire up and the car to lurch forward rather than pull away smoothly.

You mostly learn to drive around it, but I do miss those old numb throttles of the Benzes of yore sometimes.

LILBENZ230

I'm not sure which W212 you have, but that is not true for any 2014-2016 E250 or E350. We start in 1st gear at all times no matter what. I wish they had left it where it would start in 2nd gear as they all used to do in E or C mode. That would help quite a bit. But for some reason, this was changed. I actually tried to enlist Vladimir to program my car to do 2nd gear starts in E mode but he said it was not possible.

Edit: I see you have a 2013 E350. So this was a change for the facelift, apparently.

The above is the best advice so far.

Seriously, try resetting the the TCU/ECU first.

I added a Stage-1 OE Tuning to my M278 and it really woke the car up. In sport mode it took some time getting acclimated to the throttle as it's almost like driving on ice the pedal is so receptive to input.

I just looked at the OE website and a tune and a tune for your car is $900 with the MyGenius flash loader. Claimed gains are 23HP/23/TQ, which is not much; 6 bottles of McCallan 15-year might be a better investment.

Left Coast Geek

My 2016 E350 4matic 'luxury' starts in 1st in E mode, at least according to the dash display.

LILBENZ230

Yes, all 350s do since 2014. No one knows why - at least, no one on here that I've ever read. Some speculated it had to do with eco stop/start but that doesn't seem to be the case as other Benz cars had that function and maintained 2nd gear starts in E. Turning it off makes no difference.

As said above, 1st gear is so short this just results in a quick-but-not-always-smooth upshift to 2nd gear.

You can use the shift paddles and select 2 at a stop and it will start off that way. Much, much smoother.

Left Coast Geek

well, the 6 cyl W124's were all start-in-2nd until the 1993-1995 versions, with the same basic 4 speed slushbox as the earlier models, started in 1st. the start-in-2nd cars, if you give them a lot of pedal at a stop, will go 2-1-2 which is really stupid. if at the full stop, you put the shifter in 2, then 3, they'll start in 1st.
