Watch out guys, It turns off everything, ABS too! But when ive tried a few hard braking to lock up the wheels, i could not get the wheels to lock no matter how hard I tried, i had new tires on there though.
Using dyno mode for anything other than a dyno run is not smart.

This is a common trick for corvettes at race tracks, as they pull their ABS fuse to get better braking. NOT that it will lock up the rears first.
Note: I do HIGHLY recommend to use it ONLY at the dyno. I tired it once at the track and it was DEFINITELY slower for lap times. The dreaded one wheel spin was a killer. Now if you had a LSD, that could be fun
, for an experienced driver that is.

Having 600rwhp on Hoosier 335's and no ESP made for a fun summer. The car dead hooked too. I am only refering to traction control here, better be able to keep the car straight though
Then coming from the two straight aways, it was VERY easy to lock up the fronts.
I can assure you that I have well over a 1000 laps in many cars at Beaverun, but for an AMG run them ESP off, and NOT dyno.
Again, IF we had an LSD in the rear, you could get a better lap time with the electronic nannies off. But with an open diff, leave them ON as the E diff DOES help on the track.
Edit: Check my posts in the C32 section as I went into it more detail if you want the full story about DYNO mode and tracking.

I was driving around for days in dyno mode having a good time until we went to do the 60-0 brake tests we were planning and found out that ABS is shut off with dyno mode as well. I have not driven around in dyno mode since, my Mercedes brakes and ABS work to damn well to disable them.
Also, I noticed that I had many tranny issues and issue with the supercharger shutting off while driving around in dyno mode. I just figured it was time to do some repairs but ever since I went back to normal mode none of those issues have resurfaced. Has anyone else noticed this?

Turned it on and off again, and it would shift again.
I have heard others have had weird issues in dyno mode, while some have never had a thing change. I think it is like a women, VERY temperamental

PS: YES your brakes will DEFINITELY lock up, because this is NO ABS to stop it from happening.
thank you

Any help with how to switch back into normal mode? Thank you.
