Going off what the service foreman told me, maybe he was wrong or I misunderstood. You seem to be the only one with the connection to have a 2nd ECU from what I've seen. My point is, it's not readily available by the dealer and basically without some sort of backdoor like you have, you're not getting a 2nd ECU, end of story.

I don't have any connections and am only relaying info I've been given from reliable sources. I totally agree that it's not readily available from the dealer...but neither are tunes yet everyone can easily get one. It's not that difficult to get a second ECU, especially since it doesn't have to be new from the dealer. Any ECU with the same part number will work, it just has to be rewritten for your vin.

If you don't want to believe me, just ask the people that did your tune...

The amount of people doing it or not doing it really has nothing to do with it. I'm understanding why you're resisting accepting this because I had the same reservations knowing what I know about the older platform.

I'd like to keep this thread on track as it is intended to help people who have been tuned be aware of the unknown (to most people) consequences outside of just voiding your warranty. If I knew tuning my car would affect my ability to trade it in to a dealer, I would have never done it. I tuned it when my warranty expired thinking I could flash it back to stock and sell it and be done with it. It's not that simple for everyone.

getting Ecu's for our cars are easy as going to online parts store and ordering them (weistec also told me they could do it for me when i was inquiring about W4 kit and ability to run race gas tune and pump gas tune... they said they would tune the 2nd ecu for race gas no problem)

I fully believe whatever you say, but you're missing my point. Tunes are readily available because they are a for sale service. 2nd ECU's are not a for sale service officially anywhere. This is all moot because my car is long gone.

after how many times the dealer tried to blame his tune for the issues he had with the bucking/idle issues thread, i would agree with this... dealer knew they could use this to make a few extra bucks off him and did what a lot of dealers do best... $$

that's true that dealer consistently and repeatedly blamed his tune ... they wouldn't accept an alternative explanation it seems

Op thanks for informing the community with your experience.
But a tune shouldn't be an issue when trading your car in. I know it for a fact since I traded my 09 renntech sedan for the Black Series at a MB dealership.
As I always say you pay for play whether you have warranty or not.
In regards to the ECU you can clone your OEM one which give you the ability to have 2 ECUs. They can be bought at online part stores or salvage yard or over here! Again I know for a fact since I bought a spare one from a member parting out his car 3 years ago that I resold to another member
. I agree buying a 2nd ECU is not as common as having a tune simply because you can achieve the same results with a handheld device. The only advantage of having 2 ECUs is to leave your OEM untouched.
Bottom line people on the fence for modding their cars shouldn't do it.

Man if I bought this car new I don't know how I could handle 3ish years of waiting for my warranty to almost be over. If I had a 2016 I'd wait for sure.

I know this topic is a little old, but I wanted to touch base with those who shared thoughts in this discussion. I have a 2017 S550 and interested in the Renntech ECU upgrade via Flash Tuner. I'm not crazily worried about losing my warranty on the drivetrain as I'm not adding the power to run 1/4 miles or autocross (kinda crazy in an S-Class anyway), but I'd like to have more power on tap if and when I need it. I have very little doubt that my hard push every so often is going to blow the motor or damage the transmission. That being said, I'm not crazy about the idea of the car being flagged. I guess it's just the principle of it. If the car is taken in for service and the ECU is flashed back to the standard settings beforehand, how probable is it that somebody is going to notice it WAS tuned, and flag the vehicle?
I do realize that if the ECU is sent to Mercedes-Benz, they will be able to tell parameters have been changed, whether flashed back to stock or not. However, as far as I know, this would only be the case if the ECU was sent in, for example, if the motor was blown.
Thoughts and criticisms are welcome.

Funny thing is: A guy goes and buys an AMG, lets say it has 550hp and 591tq...........why in gods name is more than that needed? That's like your wife having a set of really nice C's and you asking her to get some D's put in.

Let me ask you this. Why do you post two or three pics of the same babe in the hot abs thread? Wouldn't one picture do the trick?
Anyway, there is never too much power; rather, you can only have too little traction. I've never had a car with too much power. When my warranty runs out on my 63, I will most likely get new turbos for 800+ HP. When I get tired of that, I will get a more powerful car.

It's actually not a 550
It's a 250
Thanx mate, I see........but babes and cars are not the same thing......... cars cannot top you off......or maybe they can

Maybe if you shopped at Walmart you could save enough to buy a 63? I would rather wear Walmart clothes and drive an AMG than Brooks Brothers and drive a lower end car. That's not a jab. My priorities are different and driving a fast car makes me happier than wearing $1k suits.
