Not sure if this has been posted already but went through this tonight and wanted to document it for you guys:

1. MAKE SURE TEMP GAUGE IS SHOWING ON CLUSTER, IF NOT SELECT THE BUTTON ON THE LEFT OF THE STEERING WHEEL TO SCROLL TO THE TEMP GAUGE.
2. PUT YOUR KEY IN THE IGNITION, TURN IT ALL THE WAY OVER UNTIL ALL YOUR LIGHTS IN THE CLUSTER LIGHT UP , BUT DO NOT TURN THE CAR ON.
3. TURN THE KEY ALL THE WAY OFF, THEN BACK ON TO THE FIRST CLICK.
4. PRESS THE RESET KNOB 3 TIMES FAST IN THE UPPER LEFT OF THE GLASS INSTRUMENT CLUSTER.
5. USE YOUR UPPER ARROW ON THE LEFT SIDE OF THE STEERING WHEEL AND PRESS IT UNTIL THE CLUSTER READS ESP DYNO METER TEST.
6. SELECT THE PLUS(+) BUTTON ON THE RIGHT SIDE OF THE STEERING WHEEL AND THE CLUSTER WILL HIGHLIGHT “ON”.
7. START THE CAR UP WITH THE KEY, AND YOU ARE NOW IN DYNO MODE.
8. THE CAR WILL REMAIN IN DYNO MODE PERMANENTLY EVEN IF YOU TURN IT OFF. CHANGE IT VIA THE SAME METHOD ABOVE BACK TO NORMAL MODE.

Besides the obvious (using on a dyno), what precisely does the Dyno Mode alter on the car?

It's basically a "test" for dyno's so that the ESP or any other electronic aids are off completely.

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.

You know, the fact you could not lock them might be a SBC thing. In dyno mode on the E63 the rears lock up first, easily. Usually ABS brake cars are slightly rear biased. Locking all of them just requires a good jab on the brakes.

Using dyno mode for anything other than a dyno run is not smart.

Sick. I know how I'm getting to work tomorrow

Not true my friend. ALL rear wheel drives cars sold in the US have HEAVY biasing towards the front. This is to prevent the car from spinning around in the rain or poor traction conditions. The ONLY exception to this rule are a few Porsche's, but that is do to the rear engine, not so much from the brakes.

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.

DAGREEKNYC

thats funny how it is slower for track times on a track but will throw down more RWHP on a dyno . I figure even with a one legger with traction you should see better times in Dyno mode ????

i_am_amused

In dry conditions, a good driver should be faster without stability and traction control.

For me it is way more fun on the street. I have driven many high hp american muscle cars before my e55, and they actual recomend that you turn off esp in the tunes and the hand held tuners now have that option to turn it off completely.

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

MRAMG1

Yeah, that is what I thought so I tried it at Beaverun in my C32. With good tires, I was cutting high 1:09's all day long. Second session, I tried it in Dyno mode. Coming out of every right hander, she would light up the inside wheel lousing accretion. Best lap times were in the low 1:11's

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.

nice post!

So how many of you guys tried it and were blown away?

chawkins2001

me totally different car! alot of violence involved.....

I would definitely look into your brakes if you could not lock the wheels up in dyno mode. At 60MPH in dyno mode, if I stomp on the brake pedal, the car will lock the brakes for almost 150'.

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?

MRAMG1

YES, while in dyno mode on the street, my tranny liked to stay in 2nd

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.

WHTEVO

Very cool. Thanks.

hi , my friend owns a W211 E55 AMG and it is German spec and we have tried to get the dyno mode to work on his car but with no success , some one told me that German spec cars have a different way of doing it , can some please help
thank you

esqdg

just confirming that you can do dyno mode on the 07 slk55... and if you can't lock up the brakes, may i suggest that you do a quick 110mph to 35mph test?

BrianS

Great writeup. I'm not sure if it's different on later models like yours but with my '04 all you need to do is turn the key to the first position and within 5 seconds press the reset button three times, and you get to the voltage screen then up two for the dyno screen. No need to turn the ignition all the way on.

ELITE_KOV

I just got back from the dyno and had great success putting the car in dyno mode. However, I can't put it back into normal/regular mode ...

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