Z4m Dsc off = Different car!!

I would say DSC goes off in the Z on 90% of my journeys. Unless I'm in horrendous weather (which the Z doesn't get driven in often) or I have a boring journey trundling up a motorway, then the button gets pressed almost out of habit. The traction is incredibly intrusive and nannying in the Z... it's a shame there isn't an M-Track mode like the E92 and CSL.

Agreed. In the dry I have never once had the car break traction when I wasnt expecting it or wanting it to (the top floor of the Trafford Centre car park is a drift fest even when its dry 8) ). If you keep the DSC switched on at trackdays arent you in real danger of causing the brakes to prematurley overheat?
P
moonigan, the DSC isnt used enough to cause brake overheating but what more annoyingly the dsc cuts engine power herrendously, i mean you can actually feel the engine being reigned in, why the car feels so different i think is because litterally you have complete control over the engines power, and now you can meter the power as and when you want it, instead of the dsc cutting power, sometimes at the wrong time also.
Hi Beedub,
Firstly, Congrats
My DSC was always off, i asked sytner if they could program it like that to save me pressing it ! If I remember there is a little intervention from the DSC with no light, like the auto-braking on the outside front wheel, you can feel when your brisk into a roundabout never used to light it up but foot down asking for slippage or wheelspin did, same as when skitting around on the OEM springs.
P.S Sixpeed : Your car was looking mint as ever at Lemans 8) Did you see the 288 GTO parked down the field at Mulsanne ?

I am back 
It was great
completely forgot that i wrote on this forum lol
well i tried with DSC off and .................................... WWWWWWWWWWWWWWWWEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE does the car fly.
Had another problem last week the noise with RPI exhaust
They warned me of the noise and that it was illegal .

Congrats on the baby news Beedub
I always drove both my Z4M and M3 with DSC off in the dry as it gives that little bit more freedom to play but if it was throwing it down with rain I would leave it on, if the road was a little damp I found it easier with it off as when its on it seems to intrude quite a lot and doesn't give you much proper feel as to what is really going on.

Just been out for a blast with the DSC off and it was great. Usually I can tell that it has cut power even though it hasn't lit the light of the dash, but with it turned off, I could put the power down properly without wheelspin.
In the wet it would be a different matter, but in this great weather we've got at the moment, it's nice to turn it off.

Tried it in the wet once too. And then quickly put the traction control back on..... enough said
I know what you mean!
I find you can't make use of the lsd with it on. And sometimes when powering out of a corner onto a straight, it intervenes for the slight spin coming out of the corner, but continues to hold the power back a little for a few seconds after, even though you have full grip :/
I generally turn it off as soon as I get in the car most dry days. I know I shouldn't. You never know, something could catch you out!
Yeah, thread revival!
Well firstly congrats on you surviving your 3 yrs old! lol
To be fair, I find the DSG really well calibrated and it saved my bacon a couple of times from a little prang. One winter from the -6 floor car park, there was a massive ice patch on the snail coming up and out and the car's hip stopped 2 inches from the wall - that wakes you up at 7.00 a.m! Otherwise it just intervenes quite subtly at low speeds and seems to prevent a problem before you noticed there was one! I put this down to the 99% diesel crap on the road you get over here in town.
Only rarely had it going off on small roads going at it appart from the odd occasion where it looses traction on a very bumpy road. ABS otherwise is just perfectly judged on or off the track letting good modulation and enough slip from the wheel. That M differential is really awesome, traction is just so good.
On track its not so bad either in the sense that it will understeer way before it intervenes on or off the power but the biggest issue I have is the stability control ie: the ABS hitting the back wheels in low grip conditions. I always try DSC off for some laps but the one " it" moment I had was when it was really quite wet. Found the car so poised and controllable and for once I was ahead of all those pesky 911's and Lotuses!
Re: the weight saving - it really could do with shedding weight at front, it should lake it more balanced at the limit, improve the front end feel and grip so less flicking that steering wheel from left to right. I have no doubt that those who drive their car on track at the limit from time to time know what I'm talking obout - it too busy on that front. These are structural changes though and that = muchos $$$/£££/€€€

im guessing my cars power maybe a massive issue for the stock traction control as the car is SO slow with it on its unbelievable... literally a stock z4m would sail past me if we both accelerated at the same speed in the same gear, it seems with the DSC off the wheels are JUST spinning ahead the road speed , as soon as i drive quickly with the dsc on the car doesn't accelerate properly and also the light flashes in high gear when i can feel no apparent wheel slipping ....
however normal / fast road situations are always dsc and it works well in this arena, i can't remember the last time i drove it on at the track however... years....
