Renntech disabled the limiter as a matter of routine on my full tune a couple years back. The tuner said he didn't know if the car would hit 200 or not but it should be in the ballpark. Not that the difference between the 186 limit and 200 is an issue around here near Seattle. Just being able to reach the posted speed limit with all the traffic is a good day.

Myself and my Mercedes Benz owning friends and associates all use AMR Performance for our software needs. Ironically one of my closest friends has an E63 S with a stage 1 AMR tune. Not only is his limiter removed, but he gained 132hp and 275 tq above stock. Car is a monster to drive and I would recommend AMR Performance to anyone. Definitely worth checking out (especially since they do not void dealer warranty).

Either way if the ECU logs parameters outside of normal when somethings happens, the dealer can probably figure things out when it comes to the warranty.

It is not a piggyback system. AMR manufactures their own software so they can reprogram the ECU to factory spec with their software in it. That way when the dealer plugs in, everything looks normal. I don't know any other company that does that, not to mention they out power everybody on the daily. Just my input on quality brand.

I am not offended as I also was in disbelief when I first was informed. It is hard to accept change and updates especially when certain brands have been around for so long. However, if you actually do the research (which I did) all of these claims are not only true, but proven with dyno sheets, track videos, customer reviews, etc. I apologize for being a fanboy, but it is hard not to when your car runs as good as mine does and you read horror stories about other tuning companies. Just trying to help the community with a reputable brand. Don't get offended by my post and apologies on the AMR overdose lol

They have a video of an E63 S on a dyno but I don't see any dyno sheets. I would be interested to see them.

Once the suspect ecu is there, either analysis method would likely take less than 30 minutes to complete, based on the amount of code on an average ecu. So the idea that there is no way to detect code changes, which is what ecu tuning is, is technically incorrect. The local MB dealerships may not have the software tools to detect the tune, but MB corporate certainly does.

Hi guys.Let us stay on the topic.I need limiter increase and not a tune.I do know that MB Germany can read the dump for the map if they have the ECU in the factory, but that is not the topic nor is tuning of ECU the topic.
I have MB Star Xentry Vediamo and Abrites Mercedes Commander.Can Vmax be increased with this equipment?
I have MB Star Xentry Vediamo and Abrites Mercedes Commander.Can Vmax be increased with this equipment?

Saying that modifying an ECU without anyone being able to tell is like saying I can make the sun rise twice in a day and no one could tell. It is PLAIN BS.
1. They have the open the ECU (physical modification and intrusion logged in the 32GiB crypto NVRAM)
2. physically jump the ECU (physical modification logged in the 32GiB crypto NVRAM)
4. enter into programing mode (logged in the 32GiB crypto NVRAM)
3. flash new code (logged in the 32GiB crypto NVRAM)
The most simple software would log 3 and 4, the most uneducated engineer with catch 1 and 2...
Just to make the case I went to a major tuner with a simple contract, if MB detects the tune and denies my warrantee or flags my car they own the car at the average trade-in value from 4 different MB dealerships.
Needles to say I when home without a tune...

Don't you know anyone else with Star who can plug in to your car to confirm that it can be done?
