Detecting if my dealership reflashed my ECU
Hey everyone, I did a brief search and couldn't come up with anything concrete, but I recently flashed my c63 with a eurocharged v3 tune which of course I'm more than happy with.
However, I brought in my car for minor service at the Mercedes Service center. Does the dealership normally reflash the ecu everytime you bring it into service, and if so is there anyway to tell if a car has been reflashed back to stock other than a seat of your pants feel of speed?
Thanks in advance.

Dealership won't touch the ECU if nothing is a major problem on your vehicle. Minor service like you said, they won't touch your ecu unless... Unless they've updated your ECU while you had your minor service done. I've been told that MB of Germany, have a new ECU Update file. I do not know what have they updated in the new ECU file but I know for a fact that it does lock up your ECU from any tuner to tune it. There is a way around it but you will lose your power train warranty even if you have a friendly dealership. You can request to ask if they have updated your ecu and if they did. You have 2 options.
1. Ask the dealership to "Unlock" your ECU but, it will void your power train warranty.
(By "unlocking" your ECU, it allow's tuner's like Eurocharged to still be able to tune your ECU but you will lose your power train warranty.)
2. If your planning on doing Long Tubed Header's or already have Long Tubed Header's, Some companies will match the power train warranty like Mercedes Benz does but the only problem with that sometime's is that some people like me does not live close or in the same state as the company and it will be a hassle to ship your vehicle to them to get anything fixed retaining to the power train.

Try to go past 160. That's the easiest way to understand. Also before I tune acceleration slows down around 90-100 miles. With the tune the car keeps accelerating with the same curve. (That's what I felt after tune.)

Also if you have seen MB service manuals, MB specifically asks the dealer to follow its flowcharts in order to determine if a reprogram is needed. Reprogramming is allowed only if it is warranted. MB frequently threatens dealers that if the steps are not followed, it will not reimburse warranty claims. I learned this by lurking around startekinfo.com.

Thanks everyone for all the suggestions I'll be trying it out to confirm, but seat of the pants feel after I got it back from service, it still feels like I'm chipped, and there was no mention of ecu reflashing or reprogramming in the service receipt.

Hi there.
I recently (last week) got the eurocharger v3 as well. You mai have noticed when you got it that the throttle response to your gas pedal became much more agressive (like WOT at about 30-40% pedal preassure). I sure noticed it... If that changed, that would be the one thing that U would notice easily by just driving around.
You probably noticed it too i you think about it...

I do think that they frequently reset your ECU though, which deletes driving memory. Things will become familiar after a couple of days as the car relearns your right foot.

In Europe they don't do it unless:
1. There's a 'service measure' for it (which is covered by Mercedes warranty and dealer gets paid for it by HQ) or
2. Customer specifically requests it (and dealer is paid by customer)
SBC/BCM issues are slightly different over here but that won't affect how the car 'goes'...
Kind Regards,
Eddie.

I can totally relate to the OP, my car felt slower also after service. I even sent my ecu back to the tuner to verify if my file is still their file, since they offer to reflash for free. It turns out that it is still tuned....which sucks since my butt dyne feels the car is still slow, and vbox times are slower than other recorded time or cars with similar tune.
I think I will try the data logger route since these are tools you can use for many other purposes and all other obd2 cars in the future as well. Dyno of the car is another way to get concrete data...there is really no way to tell for sure if the tune is there, other than getting hard evidence (dyne and logging) or just asking the tuner to reflash again.
