Analog 0-5V sensor ground
C2-32
AGND_2
Dedicated analog ground
Analog 0-5V sensor ground
C2-33
Analog_In_20
12 bit A/D, 100K pullup to 5V
0-5V analog signal. Use +5V Out pins as power supply and
Sensor Ground pins as the low reference. Do not connect
signals referenced to +12V as this can permanently damage the
ECU.
C2-34
Analog_In_21
12 bit A/D, 100K pullup to 5V
0-5V analog signal. Use +5V Out pins as power supply and
Sensor Ground pins as the low reference. Do not connect
signals referenced to +12V as this can permanently damage the
ECU. See 3StepSwitch 1-axis table for setup.
C2-35
Analog_In_22
12 bit A/D, 100K pullup to 5V
0-5V analog signal. Use +5V Out pins as power supply and
Sensor Ground pins as the low reference. Do not connect
signals referenced to +12V as this can permanently damage the
ECU. See USBLoggingRequestIn channel for input state. See
Setup Wizard page USB Logging for configuration options.
C2-36
Analog_In_23
12 bit A/D, 100K pullup to 5V
0-5V analog signal. Use +5V Out pins as power supply and
Sensor Ground pins as the low reference. Do not connect
signals referenced to +12V as this can permanently damage the
ECU. See ChargeOutPress [kPa] channel for input state. See
Setup Wizard page Charge Out Pressure for calibration options.
