Hi all,

I recently bought a Focus RS MK1 2002 with a performance manifold and exhaust running the original Cat. I have just put a decat on which has turned the car into a bit of an animal. I was advised that the car was set up using a Bluefin Map but the MIL light has come on on my way home this evening so I'm assuming it's because of the Decat. I will be putting the error code reader on later on but thought I'd get peoples opinion on here aswell. If it turns out to be on due to the Decat, can I turn this this off without having to get the car remapped as I believe the car has already gone down this route? Will the light being on have any effect on the running of the car i.e limp home mode etc. I will say the car seems to be spot on at the moment running wise, boosting and holding fine.

Any help or comments would be appreciated.

Cheers
Dave
