You can run it with the stock MAF.. Check out the wire pin-out sheet that came with the ECU to figure out what to wire the MAP and AIT sensor to if you want to run them..

Wiring accessories to the EMS:
Please follow this suggested wiring diagram when adding accessories such as UEGO
gauges, MAP sensors, IAT sensors, or switches for use with the EMS. Note that wire
polarity is not important for the Air Temperature sensor.

You would also want to run a wideband into the ems. Tune it via MAP and you can get more precise tuning. And if your doing a sr20 make sure to change the CAS disk.
