Yup, only differences in the states are equiptment options. Mechanically, they are the same car.

sweet!!! can't wait to get the ECU tune done!!

jgoga

I received my ECU back today and let me say WOW!!!!!!! I have had upgrades on other vehicles before but this one is really worth it. If you have a 2013 C300 this is a must do.

Timed the car 0-60 4 times:

1. 0-60 5.7
2. 0-60 5.9
3. 0-60 5.6
4. 0-60 5.7

And the response in the accelerator is immediate.

Well money spent. Call Cory @ Kleemans.......

That's great to hear, those are some pretty quick 0-60 times too. I'm hoping to hear many more good reviews like yours! I'm wondering... my car currently can't rev to redline in park, with the tune can you rev all the way up to 7k?

jgoga

No, can not rev to redline in park. Can however redline in drive

Hmm... I'm thinking about getting the K3 upgrade on my 350 O_O

Good to hear you are happy with the tune. It is not subtle.

OMG_AMG

Where exactly the ecu located on 2013 c300 ???? And how to remove it ???

As per Cory "The ECU is located on the side of the engine- picture attached. The ECU is bolted to a plastic carrier which is held on the engine via studs in rubber grommets. Simply remove the black plastic cover that covers the top of the ECU, disconnect the 2 plugs and pull the ECU out and up with a mild amount of force"

P.S. End result is typically about 315-320 HP and about 300 lb/ft. of torque.

See here:
http://www.kleemann.dk/Performance/E...250CGI_M271EVO

They claim the C250 tune on the M271 EVO results in 245 HP / 276 lb.-ft of torque.

Quite a bit more costly then the JB+ tune, but nets in more power/torque as well.

I just shipped mine out today, hopefully will have it back before the week ends.

gpotski

I am thinking about this tune also.

Now, does the tune alone really void the warranty?

JaredP

Yup, but the MB tech would need to be a computer engineer to tell the difference. I'm willing to bet ECU software is written at a very low level, you would need to be an absolute expert to tell the difference between modified and non-modified ECU software.

Does Kleeman offer tunes for the 2010 c300/350 and what kind of gains would it produce? Also can 4matic versions be tuned or does that even matter?

JaredP

Tons of companies have tunes for the M272, search around. They only seem to offer maybe a 5-10% increase in HP/TQ. 4matic generally doesn't matter.

eli_youssef

Thanks Jared, i'll take a look. I was wondering if you'd get the same dramatic results you guys are getting with the 2013's, it would definitely be nice.

JaredP

The reason the power increase is so dramatic is because the engine in the 2013 C300s are just detuned C350 engines. The M272 tunes (MY '11 and below) are typically much cheaper, and can be tuned and un-tuned via a handheld tuner.

MrMeth90

Why local tuner says this amount of gain (50hp) is impossible. Anyone have dynos?

JaredP

Because you drive a 2011, 3.0L C300.

MrMeth90

Nah. I got a 2014 C300.
Got another answer?

JaredP

Your profile says 2011, but as far as I know Kleemann is the only company that offers it. The OP said he contacted many company's that have 10-15 horsepower tunes for ~$600. But Kleemann is the only company with the full retune, for whatever reason.

Drazil

For those of you who got it, how's the mileage been like? just wondering, is the c350 tune (if one exists) the exact same thing as this one? so C350 would get ~20 hp bump only...

JaredP

C350 tune nets same result power. I would imagine mileage is the same if you drive the same on either tune.

jgoga

Because your local tuner has no clue. Add the numbers yourself, it's simple:
2013 + models have the 3.5 motor, Mercedes detuned them to 248 HP. The C350 (which has the same motor as the 2013+ C300) has 302 HP. Kleeman is simply tuning the engine to its capabilities + 20 or so HP.

I have done this tune and speak from experience. Best tune i had ever experienced.

Again, no offense to your local tuner but i would not trust anyone touching my car except Kleeman.

Money well spent...

Someone needs to post a 0-60 video... So much hype.
