Why run in dyno mode when on the dyno instead of in normal mode?
If mammary serves me, I ran a 380hp in normal mode, and 409hp in dyno mode (can't remember the dyno type but about 2 months later, I had a 451hp in dyno mode on a Mustang dyno...pfftt.). So, a significant difference in horsepower in the mode that I am in 99% of the time.
Is the number we dyno with in dyno mode the actual number we are driving around with at the rear wheels on the street?
As far as the #s being the same, yes they are. Dyno mode does not give you more HP, or provide a more aggressive tune, it's just disabling safety features to allow you to dyno, hence it being called "Dyno Mode"

I did, however, just drive my car right on to the dyno and run it without putting it in dyno mode. So I guess that is why I was under the impression somehow Mercedes had dyno mode as a means to really turn any electronic disabling device off to allow minimum drivetrain loss when on the dyno.

Surprised like most of us that it didn't really shut you down cold.
When against massive "wheel spin" like your ECU was seeing, it should have shut that butterfly on the TB down tight.
Weird.

!!Warning never try full power on normal roads as you will most likely go side ways & wont have the safety stuff to keep you in check!
Even now I still have about 2 months on my factory warranty and I have service message on and I'm afraid to take it over there...I'm afraid they will do more harm than good, esp. with the ECU. I may be paranoid but I have no assurance that it won't happen EVEN if I tell my SA.
That's the only two types correct?

Run three was NOT in dyno mode. Notice the difference in power. I'm guessing y'all are right about there shouldn't be a difference, but empirically, I can't discount what I saw with my own eyes.
Run 1 = 407.44HP 437.44TQ
Run 2 = 399.54HP 442.20TQ
Run 3 = 379.64HP 443.69TQ
Hmm? Could this be heat soak? I wonder as I look at this...anyway, the car ran on the dyno in normal mode, even though I guess it shouldn't have. I assumed the difference was the mode, but I guess it could be heat soak.
Well, I can't seem to upload my photo so I'll have to figure that out later since that website I used to use doesn't seem to exist anymore.

And this is a moot point...VR550 installed and just got home...I'll post up what I gots!
Needless to say, I'm very pleased with the results and I certainly exercised the new horses on the way home from LA! Will post more later!
I wonder if its new because of the Porsche gt lawsuit.
Thanks.
I get a warning saying EBV, ABS and ESP or disable/inoperative
Second msg to come up says Speedtronic is disabled.
Yes my ESP light stays on. When I hit ESP button while in this mod it has no effect.
I know im a newb and all, but can someone tell me what the EBV is? Also when it says speedtronic disabled how does that effect the car. I must not totally understand what that is because I thought that would mean I couldnt manually shift. WHen I try it does allow me to shift as all settings were before Dyno mode. So what does it mean?

electronic brake force distribution (EBV) .. i'd assume it has something to do with easing off brakes if w wheel is slipping under braking.. kind of like individual ABS.. but its just a guess.
Speedtronic is the proximity sensor for the autospacing cruise control.
go out and see if you can drift the car (if you're confident with your skills).. does the ESP still kick in?
so annoying.
