DD-EFI digital dash displays are designed for use with all variants of Megasquirt ECU's. They run the full version of TunerStudio and Megalogviewer (which share your registration from your laptop version) so you have full capability to tune, datalog, etc. through the dash. 

The dashes come in two different flavors (standard and pro), multiple form factors, and two sizes (10.3 and 12.3 inches), and all of them can be controlled with a bluetooth keyboard/trackpad, or you can opt for the touchscreen option.

The pro version of each dash model has all of the features of the standard dash, and adds connectivity to the Megasquirt ECU via CANbus, as well as an internal I/O expansion module that adds 7 digital, 5 analog, 1 fuel, and 2 pwm I/O's. 

The dashes come with many pre-configured gauge layouts and designs, all of which can be edited and modified to fit your preferences, or you can create your own custom display style.
