Took it for a spin and the pinking has stopped but if i advance the dizzy to much and increase the boost more than .7 of a bar i can get it to pink in 4th and 5th, so do you guys think this problem can be solved by a rolling road set up as i didnt think there is actually much you can play with on the s2 mfi set up, any info much appreciated
A setup, and/ or maybe a chip for your spec will sort it.

Fit cam pulley (needs to ne on correct timing) and belt and tension belt.
Basicly, you have to spin the crank pully to the set degrees (as quoted by the cam manufacture, or ford, on CVH usually 104 - 120 degrees, depanding on cam fitted).
Then undo vernier adj bolts, spin the cam to get No 1 inlet valve at full lift, using dial gauge.
- spin the engine to make sure belts tension'd correctly all round, and no valve to piston.
- then double check the cam dialed correctly.
- run up, get warm, and set the idle, mixture, ign timing.
Dan, do you have a decent way to determine the cranks TDC with the head on? If so, would you be so nice to describe it here....??
Thank you in advance.........
A dial gauge thro the spark plug hole.
(will need a extension on the dial gauge)
