It would be pretty cool as a replacement for the 370z left circle display.
You could even make the graphics looks like that old screen.
And since you have the data you could replace the fuel bar and temp bar with higher resolution bars on your screen. Maybe make it easily removable if the user has to access the original lcd for some reason.
Just cover this right up and put a much more useful display there.
I would definitely buy one.
with a display like this maybe?

that would be the definition of OEM plus. and unobtrusive upgrade.
