The digi dash is very cool to look at in operation. It also allows easy installation of the Trip computer when you can find one (I did!)
It lacks real oil pressure gage (idiot lamp),
It lacks of the battery voltage gage,
is more sensive to the good condition of the speedo cable and angled adaptor on the tranny side, so speed value can be bouncy to read.
It is not a simple task to swap over, as 2 sensors need to be changed (oil Press and Fuel level), and some body harness - behind the dash needs to be swapped too. Connectors are not the same. Only a couple of very experienced members have succeded a swap.
I have had the digi dash in both of my Canadian Ptypes (GTS!), and prefer them over the analog, just because of 80's look about them.
To each is own preferences!
