Some interesting info for you. Went to Well Lanes on Friday to get setup properly and it turns out my car wasn't fuelling properly due to the black ECU being faulty.

He tested this by pulling the fuse out of the heated seat part in the fuse box and lightly touching the 2 terminals with the fuse. Apparently this shoudl make the car judder slightly. If it doesn't then the fuel ECU isn't working.

Put my spare fuel ECU on and sure enough doing the trick with the fuse caused the car to judder slightly.

Just thought I'd mention it on here as alot of people don't seem to know about this.

Cheers
Dave
