This document explains how to install a 3-port boost control solenoid for
use with your NismoTronicSA ECU.
See EBC (Electronic Boost Control) SETUP
for information on programming the boost control solenoid operation.
This document is broken into two sections; External WG Setup and Internal WG Setup.
External WG Setup
Port 1 - Boost source from the intake manifold OR turbo is T’d into the BOTTOM port of the WG
Port 2 - Connect Directly to the TOP port of the WG
Port 3 - OPEN FILTER
Internal WG Setup
Port 1 - OPEN FILTER
Port 2 - Directly to Internal WG nipple
Port 3 - Boost Source from intake manifold or turbo
Boost Solenoid Wiring
Wiring the boost solenoid is very straightforward. There are two wires coming from the solenoid; 1 goes to a switched 12v power source, and the other goes to a PWM output from the ECU (which varies depending on which ECU you are using).
If you are using an SR20DE, KA24DE or RWD SR20DET ECU; then connect the PWM output wire to the stock AIV output on pin 102.
If you are using a FWD SR20DET ECU (GTiR); then connect the PWM output wire to the stock WG solenoid output on pin 111.
