The Recirc Valve wiring node in NSP is where you tell the Nexus which output is connected to your recirculation valve, the valve that vents boost back to the intake when the throttle closes. In most installs that's a DPO (digital pulsed output).
You'll need this page when you first add an electronically controlled recirc valve, or when you move it to a different output. Before testing, check that:
- The output you pick isn't already assigned to another function.
- The valve has its own power supply and the DPO is switching the ground side.
- The valve's current draw is within what the output can handle. If not, use a relay.
Once the output is assigned, set up how the valve behaves in the recirc valve settings and the recirc valve output table.
