Auto start/stop feature
Hi freinds
I'm certain this topic has has been discussed in the past. However, I'm curious if any members have had experience with this product or something similar that apparently re-maps the ECM to permanently disables the annoying start/stop feature. Product link below.
Any comments or suggestions would be greatly appreciated.
Thanks very much

This is a symbolic feature found on vehicles today. Lower emissions? If one is at a long light, emissions will be reduced by a small amount. That said, it is immaterial. I'm glad I'm 55 and don't have to tolerate much more of this stuff.

But there are savings in real life too, and several sources think it's about 10%.

Thank you for your reply and links really appreciated, I thought there may be some fuel saving especially on the V8 but I can't help to think what this continual start/stop feature is doing to the starter motor especially in heavy traffic.

C450, GLS 63 and a few other things
They've beefed up starters and/or use secondary components for the start/stop feature. I can say I'm on all kinds of auto forums where I've seen all kinds of issues that cars have, but can't recall a single post on a car with auto start stop that the starter has gone bad and needs to be replaced. (And yes, plenty of posts about people complaining about the feature and wondering how much extra wear the starter will have). It's not an issue. Those of us driving a modern V8 Mercedes have a long list of future repair worries/possibilities that are more likely and more costly than the starter....

I don't think I'd worry about a starter motor for those cars that have an inline starter generator, ISG, since it's brushless it's working all the time to add performance.
That would be all the 53s and the new 63s.

I will at least compliment Mercedes about the location to turn the feature off each time a person starts the vehicle. For me, it is much easier when the button sits right next to the ignition button-as they have positioned it.

I'm planning to use the program change from RJ automotive to remember the last state of the on/off status. That should be fine for me. Don't know about the Brabus option - is that just a programming change too?

I think it may be materially the same. Post your happiness with the RJ solution when you do it-please. I’m 4 months out.

Start/stop
On all but the 350 the 48V ISG is extremely robust and should not be an issue. I find the feature almost imperceptible on my 450.

I have a GLE63 and this looks promising. My wife drives a C43 coupe so I could kill two birds with one stone. Personally, she hates the sport mode and drives both cars so it is worth it to her. Happy wife, happy life.

The RJ coding change works exactly as described - it remembers the last state of the auto on/off between restarts. I toggled it off a week ago and it's stayed off each time I start up. Simple.

How did you go about doing this? It looks like they have a pigtail/OBD2 plug they send you, then you have a short “programming session” with them for them to change the coding? Is this correct?

Exactly - they send you a ODB2 plug for the ALCL, and it has a USB port. They supply a cable with USB-A end to attach to your PC (or Mac). You download a remote desktop app (free) from the s/w company AnyDesk and book a coding session w/ RJ. They are GMT-0 so adjust for your timezone when booking. RJ will communicate with you over WhatsApp while the coding happens and let you know any issues etc. It was fast and easy. I used a Mac w/ Parallels since the coding apps he has to d/l to your PC are intel-specific and the Mac M1 is not supported yet.

What is even more annoying is not at all being able to control the stop/start function with the brake pedal, other cars you can do this very easily. Does anyone know if the brake pedal sensitivity can be adjusted?
