This short guide is a collection of tips for people doing Barra conversions to GQ Patrols. We will update the guide as more info comes to light. If you have any tips please contact us!
FG Falcon PCM in GQ Patrol
Running the FG PCM & ZF transmission is simple. The PCM does not require a VSS signal as it gets one from the TCM via CANBus, so no extra VSS is required.
Using a CANBarra Module we can enable Tacho output, Oil Pressure, and Alternator Lamp on the factory cluster. The Speedo is run directly from the GQ Transfer case using the OE sensor. Engine Temperature is read using a GQ Temp Sender in the lower thermostat housing using the original wire.
GQ Patrol Clusters
GQ Patrols Clusters run off the outputs of the CANBarra module, which can translate the Barra PCM CAN messages into analog signals for the dash. However there were some small differences between clusters depending on the engine & series regarding the tacho:
- Most Yellow on Black Clusters require a simple modification to the PCB to work.
- White on Black Clusters (later ones)
- RD28 Diesel and Petrol EFI Clusters just work with the CANBarra directly
- Other diesel ones require a small C/R network on the Tacho output of the CANBarra to create an AC pulse.
