Specifically for E550 BiTurbo's. I was watching a video of an older SL55 running the 1/4 in dyno mode and getting a faster than stock time. I'm going to run the 1/4 in my car and see what it does and I'm thinking of trying to do a run in dyno mode as well. Let me know if any of you have tried it.

I remember, dyno mode will turn off all electronics, leaving with minimal Traction control I believe.
Hoovie Garage made a video with his 4500$ S600.

So, please check the manual before doing that.

It will turn off abs and ALL traction --- nothing "minimal" is left

try it and report back results

cocobeex

I might try that in the near future.

I'm excited to see 1/4 mile time of my project.

BlownS4

Bro I think WE ARE ALL EXCITED to see how fast your car is!!

Juice1979

be careful, you will lose power steering in dyno mode. I would suggest putting the car in dyno mode and driving it so you know what to expect before hitting the track

PeterUbers

this is the first I've heard of this

BlownS4

Here is why I want to try this in Dyno Mode fast forward to 8:35 and watch from there.

PeterUbers

Great video.... that guy makes me wanna go to the track!!

wow... 13.6 to 12.55 with dyno mode?

oh and he didn't seem to lose any power steering... myth busted

Bowyer

The drink in the cup holder is funny! Cool video, thanks. That GTR is quick off the line!

Juice1979

Have you done it? I have driven in dyno mode on my 2012 and it turns the power steering off. Try it, it takes about 30 secs to do, and then report back

raja777m

He was driving in a straight line, how did you figure it out power-steering is still working?

It says, all electronics are turned off..!

I have an interesting observation. I made LESS power in dyno mode on the dyno. Why? No idea. Common sense says I shouldn't. Maybe it was the shop, maybe the car was mad at me, who really knows. It was only a few, but still, I did.

Also - I am going to clean up the downpipes this weekend - if you are interested still, let me know

BlownS4

very odd, but if I recall weren't you in E mode vs S? I think you still have to switch that manually when you are in Dyno mode.

Hell yes I'm still interested. I thought you forgot about it tbh since it's been some time. They have cats right?

sleeperZ96BT

Send me your email (via PM). Yes, catted, 2500 miles, if that, on them. Dyno was in E mode and then dyno mode. I really don't know what the issue was.

BlownS4

really odd. I emailed you back to our original thread from when I was selling 63 mufflers...

Mikeki7

cars with hydraulic power steering obviously wont lose that in dyno mode, but if your car has electric steering then it can easily be turned off. If you are going to use it in 2012 plus car then definitely practice so you will know what to expect. At speed steering will feel normal.

Kyle Rogers

Keenan rep suggested it, I did but found it did not run any faster with my 2014 E63S model 4matic

BlownS4

ESP off, torque braking, suspension in comfort mode, transmission in S and very crappy 60ft. Yes that is a hellcat!

Juice1979

What was your time and mph?

60ft?

cocobeex

Cooooool

Where is the time slip ??



I did a 1/4 mile test on mine, "On street"....

Scare the shiiiit out of me....

sleeperZ96BT

Thanks for the video - how'd you do for ET and MPH?

Juice1979

These cars 60ft horrible which is what kills their ET. Best Ive seen an E550 sedan or CLS550 do was a 1.9x. The torque management within the TCU kills the launch on these cars

PeterUbers

hes recording the whole time and he is easily turning his steering ... watch he video in the dyno run mode when he has to turn a couple times after the run to get his time receipt/printout... he's not struggling at all and continues to make his video ... for how verbose he is about EVERYTHING you would expect him to say something about the steering.

perhaps electric steering is affected
