Dave,

From what I've read on mbworld is to keep the car in c-mode, feather the gas pedal at the start whilst changing gear manually via the gear lever rather than the two buttons behind the steering wheel.

 

Probably dumb question: what's the redline rpm on e55?

From the E55 board's sticky on mbworld

THE LAUNCH

The hardest part of the race is the first 60 feet. Practice is the only way to improve this time, but here’s what works for me.
Settings: Suspension in COMFORT mode and raised, trans in SPORT mode.
After staging, with my foot on the brake, I press lightly on the accelerator to bring the RPMs up to about 1100-1200. This takes the slack out of the drivetrain. On the last yellow, I release the brake and roll into the throttle. Simply slamming on the gas will result in wheelspin and a slower ET. The speed at which you come to full throttle depends on available traction.

 

Also, have you reset your ECU? You will notice a night and day difference in your car.

 

A little bit different topic, do you know how to get into dyno mode?

 

For an E55, sure.

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.

You can drive with it on, but be careful. Some guys actually keep it on in dyno mode at the track, but you'll need some sticky tires and some hairy *****.

 

raise the car up all the way, comfort mode, lower rear tires to 21 psi and keep the fronts up to 44psi, take the revs up to 1200-1500 and roll into the throttle taking about a half second, and go wot when you feel the car bite at the top of 1st gear. hope this helps.

the beast is a little tricky to launch well. but when it does it leaves like a scalded cat!

ECU Reset:

1: Turn the ignition key to the on (not start) position.

2. Press the gas pedal to the floor and hold for five seconds.

3. Turn the key to the "off" position (don't remove the key), then release the gas pedal.

4. Wait at least two minutes for ECU to reset.

Basically, this resets the adaptive transmission and "wakes up" the car. The car will eventually adjust the tranny for the best fuel mileage and smoothest ride depending on your driving style, so a simple reset will bring the animal out again.

It is said unplugging the battery overnight does an even better job, but you lose all your memory seat etc. settings. I've never tried it so I can't say for sure if it helps more.

As far as dyno mode, the only other reason to put it in dyno mode is to dyno the car, of course.

 

+1 ecu reset works well i must say.

You may really want to consider putting a Quaife LSD in these cars for better traction and better times. We keep them in stock for the E55 because it is such a big improvement to them. Give me a call if you are interested in adding this great bang for the buck modification to your E.

Thanks-
