Out of interest would it be the same with MSD? They are CDI and coil is not always powered only when coil discharges.
I have noticed factory set ups with those capacitors so it's good advice thanks.

Re: 12P Conversion
Generally with CDI coil neg is grounded and the box pushes coil pos negative, so momentarily the 1uF dump capacitor is across the primary. It provides this path from ground to coil pos. NEVER put a cap on the coil terminals of a CDI setup. Big currents will flow and something will pop.

Re: 12P Conversion
Ive been looking back at the wideband wiring, im going to leave the signal ground on D6 and move the heater ground from the ecu earth to a seperate earth point.
Also there a slight leak on the extractor collector so will re seal that, hopefully will get a more realistic reading at idle as at higher rpm it's more accurate.
