Hmmmm, DSC, my driving, is all ok?

anissut · 14-03-2009, 02:20 PM

So, decided to go for a blat last night to a really nice stretch of road close to where I live, very quiet, super smooth tarmac and 3 roundabouts with 3 nice twisties in between. The car is on Conti Sports which I know is not ideal but when the tyres still have 5mm tread left it seems silly to change them.

Flat in 1st DSC light going nuts. So I'm thinking that is probably acceptable due to being a little cold and never easy to get all the power down in the CSL in 1st. Also noticed that now and again doing it in 2nd. Anyway on favourite stretch, stuck M track mode on and went for a few runs. Quite a lot of wiggles and I'm thinking the car is maybe not gripping as well as my previous 2 CSLs. Then parked up next to 4-5 bikes who were doing the same as me, had a chat with them etc. then decided to do a couple more runs and then home. Forgot to stick M Track mode on and again, DSC going a bit nuts. I'm wondering whether it might just be the Contis or could it be something else. Diff was replaced less than a year ago. Could potentially be RTABS but not sure I can find out without sending it in under warranty and can't be arsed with all of that.

Any thoughts chaps? I hope it really is as simple as crap tyres.

Thanks for any advice.

Anis,

Contis aren't good on the track but they are still a premium brand and 'okay' on most cars, the CSL is a bit different though.

I have just put Goodyear F1 Assymetrics and felt they understeered badly on the road (34 psi). The roads were cold and slightly damp so I'm waiting to if they get better on 'better' days. Assuming you have checked the pressures?

If so, perhaps get Simpsons or Thorney to fit a RTAB limiter kit?

When I first got mine it was on PS1's. Looking back they were appalling and felt like as much grip as wood! So could be tyres. After tyre pressures easiest would be Thorney/Simpsons if it's real reason for concern. You don't have to be a top racing driver for wrong tyre pressure to effect you.

Something sounds wrong mate, you shouldn't be getting these sort of issues on a dry road once you have some temp in the tyres. I've not had a CSL yet but the M3's is not that far off really and I would not expect DSC lights to show on a dry road in anything more than first really. Could you have picked up some diesel do you think?

Sounds normal to me, its easy to light up the rears in 2nd - Im on ps2s.

Agreed - my car can feel squirmy occasionally for the 'usual' reasons, normally a few combined: damp patches, cold temps, oil/mud on road, heavy right foot!

I wouldn't worry too much. Fitting a RTAB limiter kit is a worthwhile mod to consider - especially if going on track

BTW - i'm running PS2s on road also.

I get the same , the PS2's are hopeless on cold tarmac, mine just bogs down with the lights flashing in 1st and 2nd, sometimes 3rd if its a poor surface, set off toady from a junction, DSC turned off, dry tarmac, 12deg outside and it stepped out nicely as i was straightening up , limiter in 1st into 2nd, still wiggling its hips.
Went back a bit later past the same junction, not a mark, never mind fat number 11's

, basically i think they need a fair bit of heat in them,would expect super hard Nankang ditch finders to perform the same , not £1200 of Michelin, (but they are summer tyres really i reckon) and some pretty warm tarmac to put power down

Doesnt help just having a plastic bootlid over the rear tyres as ballast.

That makes me feel a bit better, sounds pretty much the same as mine.

I was also thinking that I know how to exploit a car better than I did when I had my last CSL so maybe that's another reason why.
