The ProEFI Display Logger allows the user to monitor over 30 channels through a 4″ color screen. Which can display up to 4 gauges at one time, with peak and hold min and max values. There is also Knock screen and a Fault screen.  Users are also able to change the layout and have multiple user modes to give it a more personal touch. User defined units are selectable as well. This display also logs to a fat32 formatted USB stick, ALL available CAN channels with logging triggered from the ECU software setup. Never miss any data again!
