if i give my car beans ie high up the rev range i get the emissions light and the traction control light on constantly and wont let me turn it back on any ideas?

car is fitted with alta 19% pulley and alta v2 filter kit

and a scorpoion exsaust


thanks alot

Very very very very very common on a modified MINI. Get someone to read the fault codes if you are worried but I bet its the P108 error. If you drive it nicely for a couple of days does the "emissions" light go off again? This is caused by the manifold pressure being higher than expected although I still dont know why it switches the traction control off. I would guess the acceleration calculation is higher than its tolerances.

This happenned on my old S, its common thing on modified minis, should re set once engine is turned off then on again..

I`ve been getting this as well on my Lohen modified MCS at relatively high speeds. I thought it was just a glitch in the bluefin remap software.
Last time it did it was a couple of weeks ago & it reset as per ususal when I started it the following morning, but suddenly after around 4 miles of tootling along at 50mph I had 90% power failure & had to pull over. The EML came on, & the one with the engine logo and it sounded like i was only going on a couple of cyl`s. After switching off & on again it had reset itself & has been ok since ... touching stuff now

Fault triggered when you hit 18psi boost, resulting in ASC being disabled.

had mine come on a stay on recently turned out to be a failed sensor although I don't which of the three it could of been the garage replaced except it was the hardest to change, apparently it's shared circuits hence the traction issue

My engine light comes on quite a lot, today it showed error code P0420 through the Scan Gauge which is Catalyst System Efficiency Below Threshold. I'd been out using the performance box to finish the V-Power vs Tesco 99 test so it's not surprising it came on after 4 foot to floor runs. A list of error codes can be found here

My traction control light comes on quite a bit also which is usually down to the car over boosting (normally in cold weather) especially if you've changed the pulley and CAI.

Interesting to note your problem with power failure and the car sounding like it was running on a couple of cylinders as mine has done that a few times recently, although a cloud of smoke also came out the exhaust too. I took it to Paul at 1320 and he thinks it's to do with one of the sensors (forget which one) being faulty and over fuelling the car to the point where it almost floods the engine, at least thats what i think he said. Popped in to Mini to get a new sensor but they didn't have them on the shelf (two in particular go wrong a lot apparently according to the Mini Technician who agreed with Pauls diagnosis) so its booked in to have them fitted a week on Monday. I'll let you know if it sorts the problem.

forgot to mention mine misfired

which sensors please,

Paul... what are they called?

my car started misfiring yesterday so went to the garage and had melted a plug ill post a picture in a minuite. what would be a solution to stop this happening again as i said only mods are 17% pulley and alta cai, so i was thinking if i got a Bluefin and injecters maybe?

What plugs were you running?? If you melted iridium plugs then lucky escape on not trashing that cylinder......

17% pulley with cooler plugs in most cases is fine on the standard fuel system as long as you are using a decent 98+ octane fuel.

stndard bmw plugs i was using got some ngk now tho
