What this screen is for
Engines with switchable intake runners change the effective runner length to help torque at different rpm. The Nexus switches that system through one output, and this wiring node is where you choose it. Any available DPO (digital pulsed output) will do, as will other suitable spare outputs.
When you need it
You'll set this once, when you first enable the dual intake runner function, and again if you move the wire to a different pin.
What to check
- The output you pick isn't already used by another function.
- The solenoid's supply and ground side is wired correctly, since most ECU outputs switch to ground.
- With the engine off, use output testing to confirm you can hear or see the valve move.
- Check the runner actually switches at the rpm you've set once the engine is running.
