You dont "Need" a pectel board to do anything at all, period.
Pectel hardware simply allows tuners to map using Pectels mapping software. If that is all they can use then they must fit the hardware for the chip to run.
With the L8 i expect you are using we can do closed loop lambda control, air injectors, coilpack ignition, any injector up to 1000cc.. anything you like, and we wont use a Pectel board.
Cheers mate thats good to know as its you that will be getting the damn thing to sort out
