you can run a z32 with a standord ecu if you run an apexi safc and change the hotwire settigs to allow the bigger afm,, end of the day more air is only good if your getting the mapped petrol mix to match it,,
no an sarf is simply an air fuel controller,, looks like an rsm
An SAFC is a piggyback air/fuel ratio controller , it won't allow access to the ignition map which is every bit as important when mapping a car.
