Display Logger Files

All CAN Display Updates files must be unzipped and placed on the root of a Fat32 formatted USB Flash Drive for Updating!

Instructions: Power the Display Logger up fully, then insert the USB stick with the unzipped files on the root directory. The Display Logger will present the updating information, then ask you to remove the USB when completed. Leaving the display powered up, unplug the USB drive and the unit will reboot and display the new firmware (6.50) on the first screen before going to the default gauge. The operation is now complete. If you plan to use the same USB drive for writing the log files from the logger to, delete all of the files from the drive.


When updating to any new ProEFI CAN Display Logger Firmware, you MUST use Pro5 Firmware to the Pro5 CAN Display Logger and Pro4 Firmware to the Pro4 CAN Display Logger. Otherwise your CAN Display Logger may become in operable and the unit will need sent in for reboot.
