DYNO tomorrow: Questions!!!
now iv been doing my research and just want to clarify everything before going tomorrow.
Dyno Mode: thanks jakpro! http://media.putfile.com/Dyno-
just to make sure...
To turn on:
display on temperature
key in, turn to position 2, then off
turn to position 1, quickly press Reset button 3times
*new thing shows up*
steering wheel buttons scroll to "ESP Dynometer Test"
+/- buttons to "ON"
start car
*in dyno mode*
ESP not available bla bla bla on display
To turn off:
display on temperature
**then i got lost from the video
how do i get back into the menu?**after in the menu.. +/- to off and turn car off.. turn car on.
Ok now to the dyno part.
Manual mode, 4th gear, step on it and let off at 5500? 6000?
depending on what fan they have, how long should i wait between each run?
and yes i will take pics and vids
Here's the total procedure:
1. Turn ignition key to position 1 (SRS light on).
2. Make sure digital temperature gauge shows in instrument cluster. If it doesn't, use the arrow buttons on the left side of wheel to scroll through menu until it does.
3. Turn ignition switch off and back on again to position 1 (SRS light on).
4. Quickly, while the SRS light is on, push the trip odometer reset button at the far left of the instrument gauge cluster 3 times quickly.
5. Your display should now have a voltage reading, like "UB: 12.0V" on the screen.
6. Hit the up arrow button on the left side of the wheel until you get to the display that reads "ESP Dynamometer Test".
7. Now go to the right side of the steering wheel and hit the plus (+) button once to light up the "on" button for ESP Dynamometer Test.
8. Start up the car - you're now in dyno mode. The display will read "ESP unavailable Diagnostic Test". The car will stay in dyno mode, even if you turn off the engine.
9. To turn dyno mode off, turn ignition off, then turn ignition switch to position 1 again and hit the minus (-) button on the right side of the steering wheel once until the display says "ESP Dynamometer Test Circuit 15 off." Turn off the ignition - you're back to normal and out of dyno mode.
Suggest pulls in 4th gear - and hold it until it hits the limiter. Make sure you start the pulls low enough in the rpm range to get a good torque reading. I'd wait a good half hour between pulls, but that's me.
Hope that helps!

or a recommended rpm would be....?
(sorry ask very directly, its 4.21am damn time difference)

Never fails, everyone is staring, people are gathering and you can't get it in dyno.
Don't let anyone at the dyno tell you different, do it in 4th and don't let them try to do a "1/4 mile run" or anything first. Near 100% of torque hits around 2500rpms so make sure they start the dyno at around 2000rpms or so.
You'll only have a few runs before heat soaking starts without cooling mods.
Good luck...take it to um man!!
got it first shot
the RPM readings from the dyno are weird
all the pulls were done in 3rd, rolling from 40km/h, up to around 6000rpm
we shut off around then because the curve started dropping.
283.9kW @ 8591rpm
431.4Nm @ 4256rpm
yup, rpm readings are way off but we're confident the power readings are accurate

If the drive train losses are 17% (I think thats what people are saying here) then the numbers must be way off. If calculator/brain correct thats 340kW and 520Nm at Crank. Thats nowhere near the quoted figures.
Why 3rd gear?
Cheers.




Those numbers are meaningless to me ... 8500 rpm ?
Torque is way too low ... and does not compute to get the power output quoted.
You need to get your money back or ask for a re-run - 3rd gear is also no good.
no worries about the money back, it took out the highest RWD kW so.. i get a free dyno along with other freebies
If you're on a road course or the twisties, M mode gives you the added control to apply power smoothly, without worrying about auto shifts messing up the car's balance in the middle of a corner.
thats what i was asking if "dyno" mode does....doesn't automaticaly upshift and then you will bounce off the rev limiter if you stay in it. (you really don't want the car to shift up a gear on the dyno)
ASR light was flashing away the entire time.Any procedure for disabling it on the earlier cars?
Thanks.

Being new to all this, I have a question!
The Hp figures don't look all that bad to me...so is it just the Tq figures your all saying are too low. I can see that they seem very low compared to the official MB stats.
I am hoping for around the 380-400 RWHP...is this achievable on a stock 04 E55?
I live in Queensland Australia, so our high temps here might keep the figures down a bit.
Thanks for any input,
Scar
