If you aren't sure just unplug the relevant ecu plug and the MAP sensor plug and check for continuity, but the MAP sensor signal wire you need to cut down by the ecu connector is yellow and black striped. Blue from FCD to the ECU side of the cut yellow / black striped wire, green from FCD to the map sensor side of the cut wire. Red on the FCD to a switched 12 volt positive ignition feed, black to chassis ground. there are lots of J-Spec ecu connector pin out diagrams around to show where the yellow / black striped MAP sensor signal wire is on the connectors.

I actually have one on my car Chris and its quite old now but its always worked 100%.

 

Recently though my car seems to be hitting fuel cut where before its been fine so i was wondering if its

developed a fault or its adjustment has slipped because i've never had this happen before.

Tiny little pot on the PCB board with numbers on it. A decent electrician could feed a variable voltage in an re set it I guess.

 

Cheers Chris, i think i'll pop over and see Pete in his new workshop and give the car a run at the same time, he's not far from me

so rather than melt my dash i'll do that :)
