+12V_Relay_Cont
rol
0.7A max ground sink for external relay control
Will activate at key on and at key off according to the
configuration settings.
C1-30 Power Ground Power Ground Connect directly to battery ground
C1-31 CANL_Aout Dedicated High Speed CAN Transceiver
Recommend twisted pair (one twist per 2") with terminating
resistor. Contact AEM for additional information.

Recommend twisted pair (one twist per 2") with terminating
resistor. Contact AEM for additional information.
C1-33 LowsideSwitch_1
Lowside switch, 4A max with internal flyback diode.
Inductive load should NOT have full time power. See Setup Wizard page Boost Control for options. Monitor
BoostControl [%] channel for output state.
C1-34
Lowside Fuel
Pump drive
Lowside switch, 4A max, NO internal flyback diode.
Switched ground. Will prime for 2 seconds at key on and
activate if RPM > 0.
C1-35 Analog_In_7 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 the Setup Wizard Set Throttle Range page for
automatic min/max calibration. Monitor the Throttle [%]
channel. Also DB1_TPSA [%] for DBW applications.
C1-36 Analog_In_8 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 the Setup Wizard Set Manifold Pressure page for
setup and calibration. Monitor the MAP [kPa] channel.
C1-37 Analog_In_9 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 the Setup Wizard Fuel Pressure page for setup
and calibration. Monitor the FuelPressure [psig] channel.
