Hi all,

I've recently been experimenting with Dyno Mode in my '02 C32 (don't worry, I'm a track-educated driver, and I don't create dangerous situations on public roads). As expected, ESP is fully disabled (and so is ABS, regrettably). The problem I'm having is that in Dyno mode, the driving characteristics of the vehicle are completely changed, and not for the better. It is sluggish, it won't obey manual shift selections or downshift with throttle application, you can't brake torque it at all, and from launch it feels like it's in third gear. If I disable dyno mode and cycle the ignition the car returns to normal. Has anyone else encountered this behavior?

Brake torque is fine with just the ESP off, instead running in a full dyno mode.
This way u still have all the goodies (ABS & BAS) running.

what is "dyno-mode" and how do you do it?

Dyno mode disables your traction control and ABS

Apparently, it disables a lot more - I can't get it to do what I want, much like the rest of the transmission "features" of the C32.

<---- owned too many manual transmissions

dyno mode was made for exactly what it is called.... dyno!!! It does not allow downshifts (as you dont want them on the dyno) and it disables all forms of traction/braking related electronics that might interfere with your car on teh dyno. With the 04 C32, just turning off ESP wont allow you to do a burnout anymore, ESP is very intermitent with burnouts, rather, you have to do your burnouts on dyno mode.

im a little skeptical on this "dyno mode" ive heard of it a while back but knowing my luck i wont be able to turn it off lol

is there any known way to do a burnout in this car? it just wont work
(yes ESP is off!)

The bolded part of your statement illustrates the inability to do a burnout. If you can't get the car into first gear (possibly second), you can't do a burnout. In dyno mode, my C32 simple bogs down and accellerates away from a stop s l o w l y in some other gear (the display does not indicate it, it's flashing the no ESP/no ABS warning). I have to agree with you - Dyno mode appears only to be useful for...dyno! If I want my car to come alive on the road 100% independent of the ESP watchdog, how do I do it?

inability to do a burnout???... sorry buddy, you dont need to downshift to do a burnout, you leave it in first gear hold the brake and just ease on the throttle from a dead stop!!! we're not supras, we dont do rolling burnouts!!! If you guys want, I'll make a little video!!

that'll be awesome if you could post up a video!

cool... ongoing project!!! first the burnout video and then i am in dire need to make a video spanking up an E39 M5 (that was a video in the works a few months ago, but never happend b/c the M5 never came)

are you talking about the M5 that claimed he beat a CL55 Kompressor?

you hit the nail right on the head!!

Just did it a few weeks ago. Smoked an E39 M5 from dead stop by about 2 car length, twice. I have to admit that he did too much tire spin.
Then I got killed on rolling from 30, twice. Kompressor lag.. I should've done it in manual mode. The key is, get the sc to work before flooring.. in my case (rolling from 30mph) that means i'd have to be on 2nd gear.
I'm sure we'll try it again soon after a little bit of practicing..
The moral of the story: careful when racing an e39 M5 on roll.. u have to be good on manual mode. From a dead stop, no worries.

no video?

no.. sorry. We didnt know we were gonna race. We were just out to take some pics. On the way home we passed an open wide road and decided to just did it.
I think there will be a video next time.
