Is PSM Factory fit only

[bermyandy]

Title says it all really... basically can you have PSM fitted as tequipment?

[sidicks]

Yes - Costs about £1,500 I think. Not sure whether they allow you to keep the original exhaust and sell this separately?

He said PSM (Porsche Stability Management) not PSE

Ooops - trying to be helpful and didn't read the post correctly. I'll get my coat.......!!

To be fair, i made the opposite mistake when someone was talking about switching his PSE off, and i replied talking about PSM.

I think i got away with it though..>!

I would think it very unlikely/eye wateringly expensive.

New looms required, new ECU, new sensors. I doubt you would have change out of £5k.

I rarely encounter mine, and I try hard. When it does come in it spoils the fun.

Next one I buy, it won't bother me if it's not fitted.

Have you ever driven in snow? Well worth the money if you do

[bermyandy]

I drive in the snow once a year - well, i drive TO the snow once a year, and normally the roads are clear.

Would chains compensate for the lack of PSM in snow do you think?

Only the day I collected the car.

Can't remember the last time snow settled where I live, must be over 10 years.

I specced my C2 without PSM, mostly on instinctive distaste for TC in sports cars. I drove a friends C2 a while ago in a spirited fashion, and when the PSM kicked in (in a straight line) I thought I'd broken it. Horrid, horrid electronic nanny.

On the other hand, the TC in the RS6 was pretty impressive in its intervention, but then 4wd means it's more likely to trigger as stability control than traction.

Yes, scared the st out of me when I first encountered it.

Sorry for the stupid question , but is PSM the same as TC? .. I see both terms used in this thread and I always thought TC was a more primitive form (not necessarily a bad thing).

TC is controlling wheelspin by reducing engine power or diverting power - PSM has the ability to brake any one of the four wheels independently if the car is 'sliding'. PSM actually allows a fair bit of sliding to take place before it intervenes - even with PSM switched 'off' it will still come on if you hit the brakes in a slide. (I guess if you hit the brakes in a big slide then it's probably fair to say that you need some help ..!). PSM in 4WD porsches is even better as it can divert power to the front wheels to 'pull' you out of a situation.

If you were desperate for it, you could get Belton to fit MoTeC, tune your engine and use the MoTeC traction control.....

Chains usually have to come off at speeds over 30mph and are only useful on packed snow or ice. PSM works at all speeds and all weathers from black ice to diesel spills to a farmers spilled barley.

PSM's generally a good idea for a road car used on the road; it'll watch your back for you. If you really want to push on or drive on the track you can always switch it off.

If you plan to drive your p-car in the snow get 4 snow tyres for it. Those wide sticky summer tyres work very poorly on snow and ice; PSM will maximise what little grip they can provide but it can't work a miracle.
