I took advantage of the year end 20% off sale with free shipping. My car is a 2009 C350 and I took it on a 100 mile road trip over a mountain pass after the tune. I drive this road frequently and the car is very noticeably more responsive and faster. I am impressed with the added power. CS was great with Patrick walking me through the process. It's not difficult but I'm technically challenged. I'm happy and money well spent IMO. Supposed to get improved mileage also but I don't know yet. Glad I went with OE.

What would I need to buy to flash my Benz ? When you make an order does it come with the obd2 flasher or you have to do it through you're phone or how does it work ? I have a 2010 Mercedes c250 4 matic Canada, I don't see anything on the website for my model there is only c300

I would call them. They got back to me quickly. Yes, I needed to purchase a My Genie(handheld flash loader) or you can a buy an Android loader. Then you also buy the tune.

I don't think there is anything available for the C250 1.8 turbo engines. I'm not sure why other than people saying it's not worth it for the tuners to decode.

The stock output isn't bad on the engine but I'm sure some more could be squeezed out of it, especially since timing could adjusted for 93 octane fuel.

While not an ECU flash there is a plug and play box that will add about 20 HP in the low range. For a daily driver application this actually an ok upgrade.

I've also seen mention of a TCU flash. Considering how weird this transmission can get this might be a nice upgrade too.

I was under the impression that the m272 engine needs to be bench flashed?

Tell me more about this plug and play option...I'm in Ontario, Canada and have always purchased a tune for my Audi, but this is my first MB and I would like to know pricing and details for this option you are speaking of.

ghlkal

I'm assuming you can re-flash back to the stock tune if needed (e.g., for service). True?

Rodpwnz

I believe so. If you check out the OE tuning thread, they mention having multiple flashable maps, stock map being one of them.

ghlkal

Thanks

Mine isn't the 1.8 L turbo engine , it's a 2010 c250 2.5 L preface lift , they didn't have it in the states only have c300 and up there , 2.5L facelift came out 2012 with a 1.8 L turbo engine . Mine is a 2.5 L non turbo v6 , like the preface lift c300. It would be nice to add some horsepower . Maybe someone can see what I can be able to use

Rodpwnz

You're welcome.

Here is a direct quote from the thread (I wanted to fact check myself):

"Each MyGenius/Android OBD2 flash loader comes with a 4x Map Pack including:
- Tuned Premium Pump-Gas Tune (CA91, 93 & 98RON), Please specify when ordering
- 100 Octane RACE Gas Tune
– Factory Stock Tune
- Valet Tune (20km/h speed limited)"

Nope. That comment applies to the M276.

Rodpwnz

Would there be any real benefit to bench flashing over OBDII? I know in some cases it wouldn't matter if the tune is "universal", and I think I read somewhere that the m272 OE tune is.

I've had friends with COBB tunes on their BMW's where they send logs back over time until the tune has been optimally adjusted for their car. I really like the idea of a tune that has been tailored for my car, so to speak.

Are "universal" tunes much harder on the engine or less optimized than the adjusted tunes?

Is that an option with the OE tune or maybe I should be asking them directly haha...

Thanks for the positive feedback Dennis! Glad to hear you are enjoying our product.

You have it the other way around. You WANT an OBDII capable tune, because that way you have flexibility. M276 must be bench flashed because unfortunately there is no other way.

I highly recommend the OE tune. Got it done a few months ago on my 09 C300 6spd and felt a noticeable difference. Everything is a little bit more responsive and the torque band starts a little lower.

After changing gears I had just a little bit of lag and that is completely gone now.

Their customer service is incredible. I went with the MyGenius device so I could remove the tune if I wanted to.

The tune is actually custom made for your car. Once you get the device you have to download a mapping of your car and send this file to them. They will send you 3 modified files based on the mods you have done to your car. Overall, very satisfied.

Hawesome

That sounds amazing, I would definitely like to take advantage of this during the sale period...is everything just sent to you and you just install it yourself - no mechanic needed?

MB Marko

these types of threads pops up every couple months of someone saying its good but post results on a dyno then we will be convinced, its like a never ending topic but no one ever posts proof of a before and after. just saying.

Ders

It's super simple. No mechanic needed. You plug the MyGenius device into your computer to update the firmware on the device itself. Afterwards you take the device and plug it into your OBD2 port to get your ECU file.

You'll either want another car or a battery charger connected to your battery when you are doing the tune. They recommend this in the instructions that they send you.

ghlkal

I agree, and I wouldn't put too much stock in the increased HP and TQ claims without the dyno evidence.

At the same time, a tune can aid in drivability, and that's what interests me.

BTW....lets say you have tuned your W204 using the OE tune flasher then the next day you drove your car over the island and totaled it in the process can you still reuse that flasher on another W204?

SALES@OETUNING

Dynograph and details can be found here: http://oetuning.com/blog/2010-merced...-dyno-results/

Each OBD2 flash loader is tied to 1x unique VIN. Unlocking the VIN is $150 or $200 for new OBD2 flash loader.

shotgun_banjo

That is not bad at all.
