Helllpp guys. Truth or Myth about driving in dyno mode??
Long story short, that's why they don't let us legallly have Star units. I was playing around and I am always super careful but I hit the wrong button and messed up my EEPROM on my ESP unit.
Only way to fix it will be for my tech to reflash it. I did discover the car will start in dyno mode so I need to drive it down about 30 miles in dyno mode to the dealer.
We've all heard about the car going limp or shutting off with longer driving in dyno mode.
Anyone have first hand experience or know of someone who has had it happen. If so, I'll just have a flatbed take it down next week.
Ugh, one wrong button on Star and POOF.

I drove mine 10 miles back to the office in dyno mode after hitting the dyno last year just to see how it responded. I didn't notice anything different from a driveability standpoint. I know that you lose ABS and some other features, so just don't wreck and you should be fine.

Man, you're gonna LOVE it. I don't regret mine at all.
REMEMBER, Benz gives you a SIM mode in Star so go to programs and look for the Sim. That is a simulator for you to learn/play around with Star so you can get the feel for it. Sim works and pretends you have a car hooked up to it without fear of damage.
I actually have the "developer" version which allows you to go deep into the car. I ended up inside the coding of the ESP unit and when I realized this was serious stuff, I backed out but hit F2 (which erased the line of code) and not F1 which is always "back up a step" in Star. Use F1 first if you ever have a question. F2 is always execute a command.
You'll understand once you get inside Star and start learning.
It's a bit tricky at first to figure out what is happening in Star but be patient and you'll catch on.

MYTH
I've driven my car a bunch in dyno mode without any limp mode. I've done it over an entire weekend and all day long at 3 track days.
developer? huh? anyone have "the best" setup to buy and is it really just $5k?

if i drive in dyno mode for too long it gets stuck in a specific gear, it will then throw "incorrect gear ratio code" and must be taken out of dyno mode and do key on key off to clear itself. This happens almost every track day and has happened to a few other V12tt platforms as well but cannot confirm on your platform from memory.

the car does not "open up more" in dyno mode. Dyno mode helps at the drag strip in two ways, with ESP off you cannot do a proper burnout, and with ESP off if the car senses wheel slip it will still attenuate power, in Dyno mode it wont.

So that is the same as in our cars, right? That is the main reason I used dyno mode in my 2wice at the strip was to get the DRs hot. I didn't think that the CL600 dyno mode was that different but thought I'd ask.

On my 2004 C32, the car would go into limp mode after a few hard runs in dyno mode; and the only way to get it back to normal was to turn off dyno mode. In contrast, I could drive the E63 all day long in dyno mode without any problems

I have been wondering the same thing. Good to know. I was planning to run at the track in dyno mode when running drag radials and power breaking till I find a good rpm to launch. It seems this would give the most ideal 60 foots on our cars.

I drive my SLK55 in dyno mode all the time and no problem. I hate the Mercedes traction control and the only way to really disable it is dyno mode. Just don't try that in the rain

be careful, you ABSOLUTELY CAN go into a fault mode which is not safe if you're in traffic. it's not limp mode in the typical sense but i've had the car get stuck in a random gear if i try to stay in dyno mode for random driving. as mentioned, you have to take the car out of dyno mode and pull the key to get it to reset. i've done it more than once just to confirm the cause.
btw, since it was brought up...there's no need to go into dyno mode to do burnouts at the track and you're not gaining any hp. you can get your tires plenty warm by simply turning esp off.

Another AMG guy helping a brotha out.
Thanks so much to Brian S for taking some screen shots of his car on Star. It was a simple highlighting and saving error (it's a star thing)
Fixed it and I am back in business.
Again, CAREFUL to all you Star rookies!! Like me..
