Hello guys hope you can help.

I have fitted cosworth Management to my Rs turbo 2.1.

When i first start the car it runs fine.

When i try to re-start the car after it warmed up ect i find it hard to start.
I took the plugs out and they are as black as the ace of spades which makes me think i am running mega rich clean the plugs put them back in and all is good again.

What way do i turn the screew on the ecu to lean it out??

Its only running base map at the moment until its run in.

Cheers,

Jim
