Hi Stu - we had the car running with the ECU without the pectel board yeah.
As for the MAP sensor - we borrowed a wiring diagram for L8 Cossie's and checked the pins to the ECU if that's what you're thinking, or do you mean to break the circuit for the choke on the map sensor so it doesn't send a signal to the ECU - if you could explain that a bit more that would be a great help.
The 3bar MAP sensor is a new one as well - bought from yourself in fact last year!
Cheers,
Andy
