Does a phase sensor need to be gaped??? i've it neds to be 8 thou how true is this as i fitted but car runs fine??? and also what gap should sparks plugs be 071c's???engine spec as follows

205 Block,
forged 0.5 4x4 pistons
stage 2 ggr head std cams
stage 3 t34.055
on yellows atm with stage 1 ecu but will be on greys with msd evolution chip

 

Phase sensor gap is 0.2mm to 0.3mm.
They will run wildly either side of this, as mine did even though it was touching at one point, owing to the top bush spinning in the dizzy housing.
I used 0.6mm gap on stage 1 with AGPR12PP8 plugs, now on IK31 with same gap on stage 3.

What Tabetha said

 

Bit of a dumb question but what does it mean by the Phase Sensor gap being 0.2mm or 0.3mm

Am going to be fitting an new one into my coss and not too sure what to set it at 0.2 or 0.3?

 

The gap as stated by ford is 0.2mm TO 0.3mm, but they will work anywhere around this so don't worry if not exact, just make sure alignment is bang on, otherwise it will overfuel BIG time, if it does not recognise the phase, because it is too late, ie retrded in relation to the cams etc.
