Could anyone out there shed some light as to why my ASC light comes on when i drive that the car hard I.E it tends to light up at 6500 RPM in 3rd Approx 110mph. This keeps the traction control off until i stop the car & switch off the ignition, this then resets the traction control & works fine until next time

Take the pully off!

Its cause you are exceeding the 18psi range...

17% pulley on yours?

i have the jcw (approx 11%) + the GTT +3% lightened crank pulley. this should mean around the equalivent of a 15% supercharge pulley on a stock MCS. Lots of cars run that , Do they normaly have this issue?
How does a excessive boost pressure cause the ACS light to come on !
by the way i know there's a high boost as the small snoot boot keeps blowing off, I'm going to order some 5 ply ones fron GTT in the morning.
P.S thanks for a quick responce.

Had this (although DSC) on my standard MCS, Mini garage fixed it and said it was a traction sensor.

Silent1 · May 14th, 2008, 05:21 AM

Mine does it at 155mph

I have (still) the same JCW+GTT combo and mine used to do that also especially on high autobahn speeds/5th and 6th gear. Perferctly normal I guess and may also depend on temperature btw.

Problem disappeared after fitting a freer flowing head

lots of cars have the problem. its a feature

But I cant answer if its the records boost pressure for the engines calculated torque figures that actually cause the traction control to shutdown.

When you give Roland a call mention it and see if he says the same

Well that kind of answers if its boost or power related then

Hi,

Go to a garage that has a code reader and get the fault codes downloaded. That is the only way to know for sure. It could be overboost, it could be a faulty sensor, it could be a lot of things. The only way to know for sure is to look at the fault codes

Cheers
