Hi all..My buds ST150 here in South Africa has the cosworth 240bhp cam set and dreamscience installed..The car drives for a few days and then the management light comes on.He plugs the DS in and reloads the software and then the car is fine..The light goes off..None of this happened when he had the cosworth 200bhp cam set in..Is this the cars computer box playing games??Any ideas on what the problem could be???

there appear to be many many reason for this and yes it can come on and go off after driving, I thought DS can turn it off, other possibilities we have been discussing is protecting the Hego sensor leads with heat insulation and even moving the leads further away from the exhaust as possible.

Kaxe where art thow for the above question ?

Hello peeps!

Yeah my engine light has been on for a few months now...

When I have a nice careful long drive and run the cossie cams in a bit it goes off but lately the weather has been pants so I haven't been on any long drives. The power/sound is still fabulous though...

Hi Kaxe..May i ask what size cossy cams do you have in your car??Thanks for the info..

i think he has the 200 ones
