Important Notes
Auxiliary Output Channels 13-16
These are high current Half bridge drivers which switch either to ground or 14V i.e. they do not have a high impedance or OFF state. When the ECU is powered OFF these Auxiliary Channels by default will be switching to ground. This means:
- Solenoids or relays connected to these outputs should not use a constant or hot battery feed.
- During the ECU powerup sequence, any solenoid or relay connected to these outputs should have a managed power feed to avoid momentary switching during powerup.
Constant 14V Supply/Backup (Pin C53)
This pin has two features:
1) Flywheeling for Auxiliary Channels 1-8. Any Inductive energy will be sent to the “Constant 14V Supply” pin. To minimise any EMI and allow solenoid current recirculation to operate correctly this pin should be connected to a constant power supply. If this pin is left unconnected the back EMF will be clamped at 45V.
2) Internal ECU EFI Relay function. When power is removed from pins " ECU 14V Supply" the ECU automatically switches to the “Constant 14V Supply” to keep the ECU powered. This will allow the ECU to complete critical tasks before shutting itself down (for example, DBW Self calibration and ECU Logging data storage).
To enable this function, set the EFI Relay Control Channel to “Internal EFI Relay Ctrl”
NOTE: With a Constant 14V supply wired, the ECU draws no additional current when OFF.
Analog Sensor 0V Reference (Pin C28, C29, C30, C31)
As the name indicates these should be connected directly to the 0V (Ground) pin on any low current analog sensor, for example Pressure or Temperature.
- DO NOT connect these pins directly to the Engine Block or ECU Ground. These are dedicated and specialised ground outputs for all analog channels and should be connected directly to the sensor.
- DO NOT connect frequency-based sensors to this ground; for example, an Ethanol content sensor. Use either the Digital Input Ground Out pin (A31) or the main ECU ground.
