Hey guys, I took the car to the 1/4 mile for the first time last night. I was hoping to run in the mid 12s but to my disappointment, my fastest time was 13.03. Best time as follows:
2.19 60 ft
5.64 330 ft
8.50 1/8 mile
13.03 1/4 mile
It was my first time so obviously no expert so I'd like to know whether it's just b/c I'm not driving correctly or it's the car. I was at Sacramento Speedway and temp was around high 70s. There was a wind however not sure of speed or which direction. I tried both in manual and sport mode. The fastest time was in manual. I never lit up the tires b/c this is my daily driver. Please advise and maybe answer some of the following questions:
1) did you burn out
2) left foot on break and build up revs with right
3) etc.
Please don't turn this thread into bashing or telling me I should have bought a E55 or go to the search funciton. This is just an honest question.

I would not stress about the trap speed until you can get the car to launch and not spin (It seems you have tire spin). For example, My Mercedes GL450 with like 320 hp and a 5500 lbs had the same 60 ft as your 517 hp sevelt E63. You get a 2.0 60 ft and you will see about 3.5 tenths quicker on average.

dyno update
so here are the results of the dyno. 419 hp and 375 torque. guys on the dyno said my peak is weird and it's plateauing and running rich. Contacted guys at kleeman and they said it's not rich and without knowing prior dyno it would be hard to say. they stated that it looks like an intercooler problem but wouldn't that be detected during service?

Those specialists at Kleeman are sharp as a bowling ball. Uh hah looks like an intercooler issue LOL
You never know that special tune for your E63 may actually be for a E55

This is the issue. Many ECU's will not command full timing until 150-170*. It will also command a lower lambda afr. This coupled with the oil being relatively cold and a poor 60' lend me to believe the car will perform as advertised once allowed to get to normal operating temperature. Was it dyno'd stone cold as well? In looking at your AFR on your dyno chart it seems to show symptoms on an ecu pulling timing. I have seen charts like that with a slipping transmission/clutch as well. FWIW, an AFR of 12.4:1 and lower is considered rich in a NA application. Lower than 12.2:1 is flat out unacceptable.

Maybe I missed it in here but what was your ride setting? Comfort or Sport? May sound strange but I've heard using Comfort is this best setting for the strip, or is it take it out of Sport II mode. I think it's both. I forget.

In order to be in Comfort, you have to take it out of Sport II. It's the same switch.
As far as the advice, yes that is true. Being in Comfort mode allows the suspension to "rock" backwards on take-off, planting marginally more weight on the rear end.
