I have spoken to omex and decided to opt for a new omex ecu. By the time u buy all the omex parts ur into about £1200 ouch. But far better than fords new k jetronic at £850trade plus £300 superchip, and as i am building the car from scratch, i also need an ecu etc in the first place to send to be chipped. Also the new system comes with new wiring, so no messing around with the antique ford wiring looms.
