I have the UG. It was much cheaper. It had more data available on each screen. And I think it looks better in our cars (the rounded corners of the black plastic housing fit the OEM dashboard design better than the ScanGauge color and form).

EDIT: btw, if you have the stock wheel/tire sizes your HX will likely show 2300 RPM at 60mph in 5th gear. My old DX trans showed maby 2450rpm, and my 93 CX/VX trans about 2050rpm at 60mph.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
