Hi all,

Just wondered if I can adjust this myself due to my car detonating at 15PSi so I have had to back it off. Took it to well lanes and they said it was to do with the fuel ecu. I have replaced this with a know good one and the car still does it. I've heard about adjusting these to allow more fuel to be to put in at the top end of the rev range. Has anyone done this?

Any help would be appreciated.

Cheers
Dave
