The air pump wiring page in NSP has one setting that matters: Air Pump Output. Choose the ECU output wire you've connected the air pump to. Normally that's a DPO (digital pulsed output).
A secondary air pump is a motor and draws far more current than an ECU output should switch directly. Use the DPO to drive a relay coil, and let the relay supply the pump. Fuse the pump's power feed to suit the pump.
Before you run the engine:
- Make sure the output you chose isn't already used by another function.
- Confirm the relay clicks and the pump runs when the ECU switches the output on.
- Check the pump and check valve lines are connected and not leaking.
When the pump runs is set on the main air pump page. Running an Elite? See air pump for Elite.
