Help improving my launch on 440i xdrive GC
Newbie here. How are you guys launching your xDrive cars? Here is the dragy from my best launch. Launched at 2900 RPM in sport+ without launch control.
Launch control was slower for me (4.18 in the rain and 4.15 dry). M2 into S2 launch is slow until 20-25mph (4.4). My manual shifting isn't as smooth or as quick either. Best launches seem to be with brake throttling in sport+ mode without launch control. 440i xDrive GC, BM3 E30 stage 2, VSRF catted, AP intake. About 70 degrees, full tank of gas. I don't know how much power the car makes but it runs well. I realize this is a heavier car than most of the ones around here. Is this around the best I can expect or can I improve these numbers? I am waiting for HPFP options because I don't want to deal with meth. I am not sure what else I can do with the car at this point but I want to be quicker. I would appreciate any tips with launch or mods. I would appreciate your numbers as well. Also how much of a difference can I expect with cooler weather and less gas in the tank? Thanks in advance

Have you tried DSC off? With X-Drive you should be able to do better than 1.92 sixty.

Definitely try it with DSC disabled. I got my best 0-60 tonight with it off; (3.92/3.67 with rollout) and that was on an upward slope of close to 3%. Would have been in the 3.80's if I'd been on flatter ground.

Should be going with CPI and E85 soonish. Looking forward to the new numbers. Looks like my current numbers are a little higher than others with the same mods but are pretty decent.

Did a little better with DSC off. I was also able to be more consistent overall with multiple launches. I still can't tell if DSC off or Sport+ is better because I was able to do a bit better with Sport+ as well (3.98 on a slight incline with a better 60') Screenshots are from best launch from yesterday with DSC off.
Overall I am loving the power delivery of DSC off without the higher revs and aggression of Sports+. Anyone use DSC off for daily driving? Keeps showing off those numbers guys. Solid67 You should post some dragy numbers with current setup before you get the CPI and E85 tune installed

I spend most of my time with DSC off these days.

Went out tonight and did 3 0-60 pulls. 3.7 is the best I got for the night. Wish I had done some tests yesterday since DA was about 200-300.
