Air pressure recommendations?

Sure fire ways to actually get DSC off perm until engine power is recycled? (I'm going to try the 6-12 seconds, 20 seconds, 6500, accessories, etc approaches)?

My guess is I'll hit that 6500 barrier so many talk about...

Follow these steps:

SMG or 6speed? There are certain methods that work on each car...

For SMGII equipped e46 M3s, this is what I've found that works, you will have to run the car twice in a row to dyno it correctly... I've not yet tried to see if you can avoid dynoing the first time and just get by by starting and turning off the engine to avoid unnecessary heatsoaking.

1) insert key into ignition, turn to accessory
2) press DSC button for 10 secs
3) start car and begin dyno process
4) when the car enters the upper rev range, the tach lights will illuminate and the engine will cut out at 6500rpm
5) spin down and shut off the car leaving the key in the ignition
6) turn to accessory
7) press DSC button for 10secs
8) start car and begin dyno process, when entering the upper rev range the tach lights will NOT illuminate and the car will not rev to redline should you so desire.

Note: your car will display a "check engine light" after this process, recording traction control errors. 3rd and 5th gears are the most commonly used ones for dynoing.

If anyone would like to see if you could avoid step #4 and post results, I'll update the FAQ. For the fuse pulling process, you can click my sig.

Cheers,

Nods, those are the ones I meant to infer by my post (i.e. I'm going to try the 6-12 seconds, 20 seconds, 6500, accessories, etc approaches). It just seems kinda 'hacky' so dunno if they will work ;)

Will post what happens...

no go on 03 SMG dyno...

Tried just pushing DSC -- no go (by no go I mean I hit limiter at 80 mph in 3rd, around 6k rpm)

Also tried the hold DSC for >6s <12s -- no go.

also tried
insert key to accessory
hold DSC 10 s
start
shut car leaving key in ignition
turn to accessory
hold DSC 10 s
dyno

a couple times

...no go.

The final method did yield DSC light perm on (and SMG problem light and ABS and brake lights), but still stopped at 80 mph (around 6000ish in 3rd). BTW -- problem light, etc all go away after a minute when you start driving again.

Didn't try the fuse #34 trick. Want to do more research...

I just want to get a baseline so I can post what happens when I add Dinan's CAI (once it comes out)...

i heard even shutting off the sensor that tells the car to stop didnt work. i dont know if its possible or not, i dont know how dynos work exactly, but the front wheels have to be moving the same speed as the rears for it to work. Could you put the m on a 4 wheel drive dyno and spin the fronts as fast as the rears? i dont even think they are motorized tho but maybe someone could hook up something like that. i dunno :dunno:

I don't get the whole 6500 rpm or what not. Is it cause smg won't let us go past 6500? Sorry if this was a repost. I've hit 7500 before. just wondering guys
