After driving on the OE Tuning tune for a month now, no problems to report - no regrets! I still enjoy how fast the car is off the line and when passing traffic. The car is rarely out of "S+" DYNAMIC SELECT mode so the engine revs mostly above 1500 RPM, making all that horse power instently available. Keep us posted...

Sheepy

Keeping an eye here!

Check out the dyno chart on the OE Tuning page for C300 turbo - I guess there are no glaring flaws in my dyno procedure / results...

I'm planing to drive my car down to OE Tuning soon and do an dyno on their machine after doing the tune but the problem is I'm going to install the AWE Exhaust system and then take it for dyno.

JBMCL

Thinking about either BMS or OE.. Hmm

- VBox hasregistered 0-60. 6.4 sec

At 75 mph with A/C on, the computer now shows ~40 mpg.

Any update on this? Seems hard to believe there were no changes to your 0-60 time, but I'm curious if you retested with different results, or if you hear back from OE Tune.

So l did the tune from OETuning as well, and I couldn't be more happy. Ordered on Prime Day while they were doing 20% off. I've driven 300 miles since I did the tune. I didn't dyno the car before and I'm not going to dyno it now (that's been done earlier in this thread), but I will say that I'm impressed with the tune for a number of reasons.

#1) It certainly feels faster. Probably not 60HP faster as claimed, but my butt dyno is impressed with the improvements. The turbo lag seems less severe, throttle response is much better, and the car just feels much peppier; on the low-end, at least. Once I'm up over 50mph, the car feels about the same in S+ mode as it did before, but around town, it has got a lot more oomph.
#2) Torque feels more substantial and shift points seem more logical. IMO, the stock shift points were a bit rough and always felt too late.
#3) Speed limiter is removed though I haven't tested that out.
#4) Fuel economy is better (although, I've been driving with a lead foot lately since it's so much more fun to drive). Highway fuel economy before @80mph highway was 33mpg. Now it's registering as 42mpg. City fuel economy with same driving is about 3-4mpg better.

All-in-all, the tune is definitely worth doing. Don't know if the improvements are greater than those of the BMS, but I don't care. I love driving this car now and it's got that engagement level that was missing before. Must-do tune for any C300 owner, IMO.

A quick update for those who're interested:

Got a Vbox and made a few 0-60 runs. 6.37 sec is the best result, which is 100% stock.

Good thing I did not follow up and get the OE tune. I'm more leaning towards the burger motorsports piggyback I wish terry advanced the tune from the beta stage.

JBMCL

Me too..was hoping Terry would make it even better! Just like what he did with the BMW's

DapperStyle

Sad that Terry/BMS said he will no longer be supporting the development of the tune. Could be lack of interest from the community, no money in it, not worth the R&D etc. It doesn't help that MB makes it super difficult to mod/tune their cars, BMW will continue to be BMS's bread and butter.

OE Tune has been in business for quite some time so I don't doubt their ability and knowledge. There should be a logical explanation to no changes in performance in my case. The dyno runs by other forum members show that there should be power gain. Many things could have gone wrong. After all, **** happens and all that matters is how things are handled.

That being said, would I recommend OE Tune to anyone? No...not right now. I'd advise to wait and see how the story ends.

SALES@OETUNING

Ok. So we got recent VBOX runs sent to us. Unfortunately the original VBOX runs and first VBOX runs we learned about and requested were not available to send to us to compare. We do require CAN logs and/or Dynos in order to trouble shoot. Without dynos or data to support running condition, it is very hard to accurately move forward when the car is on the others side of the country. We are happy to work with you, and will wait for the information we requested to be provided. We have not a experienced "zero" performance change after installing our current C300 2.0T tune on any other customer's vehicles, so this is why we need more information.

This would be best handled off line and the end result posted.

Neither party ever seems to look good in back and forth forum posts and I'm sure that's not the case here...

Hope it's all resolved soon, and genuinely looking forward to hearing the performance result in the end...

All the best..

Respectfully I feel handling this situation in "the public eye" has tremendous value. The whole concept of an ECU tune is almost entirely a one way trust exercise - based on the tuner's reputation. We ship an expensive piece of electronics, effectively disabling our vehicles, (potentially for weeks should something go wrong) install it in to our cars, and start the ignition trusting that the work was done correctly. How Sales, Technicians, and Customer Service handle this process is of paramount importance and a forward leading indicator of how much trust we should extend in the future. It is unreasonable to put the burden of proof on the customer if such wasn't explicitly stated at the onset.

I would suggest to OE not treat this as an IT case, pull up from the bits and bytes, and treat this as a customer satisfaction issue. There are many ways (commercially) to make this right. The longer this goes on the more permanent the damage will be.

SALES@OETUNING

In situations like this, where the car is not local to us, we require data. CAN logs and Dynos are essential requests we put to the customer before any trouble shooting begins. As soon as we get the info we request, we can then look into this further. The longer it takes to get information, the longer it takes to get the answer from us. We just don't make guesses when technical data is the only way to confirm and address any current operating condition. We offer full customer support and customer service after all products are purchased. This service is only an email and phone call away.

Shadwell

Yeah Fair enough, many ways to achieve an outcome..


IME better resolutions resutled in direct comms with direct conversations followed up with written minutes to prevent confusion. This is ALWAYS in the case of a reasonable, respectful and caring vendour and customer working amicably to resolve. Of course not every scenario has the latter ..


Anyway looking forward to the technical solution and increased understanding it provides to all of us.


Cheers.

Spoke with Rocco yesterday. He confirmed that they are, in fact, having a 20% off Labor Day sell on the C300 tune.

For any who are interested.

I'll taking advantage of this, of sure.

Used this thread recently in doing some research on finding an inexpensive tune to put on a C300. Since it was helpful I thought I would share an email I received this morning from Dinan (BMW tuner) and apparently they are delving into the MB market as they just released a C300 tune today. Looks similar to the Burger one but a bit cheaper ($300) and has bluetooth. Nothing monumental in gains but still respectable for the price tag. Another one to add to the fray.

May try it out since the wifes C300 could use a little fun mode for when I drive it. Always have had good experiences with the Dinan parts I've had on my BMW's, even if my wallet isn't happy about it.

jatt143

let me know how it went.

Wkar275

I definitely will be purchasing this tune in the near future. The numbers look honest and the price tag is great.
