Mac valve setup

[Acole1017]

I have the 350z plug and play ecu and Im trying to wire in a 3 port mac valve. Everywhere ive read tell me to set it up as aux and i have aux 14 and 15 in the expansion loom open but when i go to boost setup it wont let me select any aux as the source.

Only aux 1-10 can do PWM type functions.  There is Aux 6 & 7 available in the engine bay in the o2 sensor plugs so one of these is probably easiest.
