ok, you have to use a 95 200sx OR 95 G20 ecu with a type 4 nistune board, you should of had this all installed from where ever you bought the board from since they know exactly what to do.. when i took an ecu into a local place to have the shit soldered i had to show the guy Exactly what to do.. lol
and yes you could then use whatever maf you want.
just drive with what you got an when it comes time to put the nistune ecu in switch to a n60 for simplicity.
