1) car off
2) turn key to position 2 (everything on but engine off) and wait a couple seconds that the lights on the cluster finish turning on/off.
3) hold DSC button 8 seconds
4) press sport mode
5) start the car
6) rev car to limiter (it will stop at 6.5k, still)
7) turn off car
8) repeat 1) to 5). The car will now be able to rev all the way to 8k

I've done it and it worked ! it works only on pre 03( or 02/4 IIRC) M3's.

Sweet I'm going to try that soon, my car has a 02 motor/ecu but I don't have DSC, I have my stock ASC will this still work for me? I can still try it off the dyno as the car won't rev past 6500 in idle correct? Don't want to get to the dyno again try and not have it work and pay for another dyno session lol

I would say go from about 3,800 rpms slowly letting of the clutch then hammer the right paddle, and hold on for dear life. At the end you will thank me.

Gotta start somewhere. I'm scared of 1/4 mile. I break
everything. So I don't know if me and 1/4 mile will mix well. Good luck.

If it's your first time skip the water box, and no burnout, just take off like you were at a traffic light, racing. Don't worry about cutting a good light. You're not really racing yet, reaction time isn't important yet. Learning how to drive the car at the track is. For your first couple of launches, just focus on getting off of the line smoothly. Don't forget to make sure DSC is turned off. Then start to increase the rpm's on your launch. Getting off the line is one of the most important aspects.

You are going to be anywhere from 2-3 seconds slower than your best time of the day when you start.

I don't think 3K will spool that 67mm.

It will probably bog then go.

i was told years ago to lower your lbs of air in the rear so

I think lowering PSI in the rear tires does make a difference, but it will depend on what profile tire you're running as well. My best ET was done with tons of weight in the trunk and with the tires nearly 10psi below what I run on the street.
the tires could expand and that way you would get a wider patch of rubber on the ground so the tire would grip better.....

I tried a LOT of things back in 2006 to get better traction, and not everything you think would work does.

I remember at one point swapping from a 245 street tire, to a 275 "R" compound and spinning more. I also ran the car down to 10kms left in the tank, then filled the tank up and ran identical ETs, but with a slightly slower MPH.

My favorite was buying a jug of VHT traction compound, and applying it directly to my tires.

I still have the jug.

Tire pressures did help, but only once I figured out how to let out the clutch slowly on launch, and feed in the power. It's a lot harder than it sounds. Basically, I launched at say 1/4 throttle, then progressed to 1/2 throttle while feeding in the clutch. Once the clutch was all the way out, I'd add a little more throttle while "feeling" the tire spin. Most of the time the peddle would be all the way out and I'd have to shift into 2nd....no chance to add more power. 2nd gear was a little easier.

Eventually I got sick of spinning....and moved to slicks.

2009 I had too much traction.
