GPC 1-4
General purpose control PID type.
These tables can be used for variable camshaft control or any general purpose PID
control.
Variable camshaft control setup.
1. Select camshaft I/P under "M1,I/P HSI".
2. Setup camshaft tolerances under"M1,Variable cam setup"
3. Select an O/P(PWM type) under "M1, O/P Setup" Subaru select PWM with 1khz
frequency.
4. Setup "GPC setup" setpoint and feedback variables and the "GPC name" If
controlling 2 inlet/exhaust cams, use one table to do each of the two groups.
5. Setup "GPC inhibits" Recommended disabled
6. Setup "GPC Setup table" and "GPC table"
7. Tune PID loop "GPC Tune".
General purpose control
1. Linearize sensors "M1,I/P Analog" and make sure limp home values are logical.
2. Select an O/P(PWM type) under "M1, O/P Setup"
3. Setup "GPC setup" setpoint and feedback variables and the "GPC name"
4. Setup "GPC inhibits"
5. Setup "GPC Setup table" and "GPC table"
6. Tune PID loop "GPC Tune".
GPC 5-13
General purpose control On/Off type.
These tables are general On/Off types. These are not PID types. They cannot have
tunable feedback with these GPCs.
To setup an on/off
1. Select an O/P(PWM or on/off) under "M1, O/P Setup"
2. Setup "GPC setup" setpoint and select a GPC name
3. Setup "GPC inhibits"
4. Setup "GPC Setup table" and "GPC table"
• On/offs do not need high precision tables so select user table E,F
O/P Air con
Select O/P and polarity under "M1,O/P setup".
See also O/P Fan1 as this has some setup for the A/C fan control.
Typical O/P=Non PWM type.
O/P fan 1
Select O/P and polarity see "M1,O/P setup".
Typical O/P=Non PWM type.
NOTE, This also controls the air con fan.
O/P fan 2
Select O/P and polarity see "M1,O/P setup".
