The timing on a proper FRST with the flywheel CPS sensor is not adjustable unless you use the octane ground cable and that only retards it by 2 degrees IIRC. However on a car that has been converted to EFi using a aftermarket trigger wheel then it often is adjustable. You then need to set the timing to be 10 degrees in diagnostic mode in which case it will be spot-on.
I'm sorry if I didn't explain this very well before - I wrote the reply in a hurry.
oh right ok sorry mate my fault aswell,ive converted the car 2 efi using all xr3i bits and my turbo block had the hole 4 the cps so i just used the efi flywheel aswell,ive tried the fault finder on the car but not sure how it sets the car into diagnostic mode
