If it is, can anyone explain me ?

LFS has a number of programming interfaces, one of which is called Outgauge. This provides a live feed of values from the dashboard. With some programming and hardware you can setup something like this.

I'm not aware if there's an "off the shelf" product.

"LFS Dashboard" is an app that shows speed, rpm etc on smartphone:

Not excactly the same as "real" gauges but easy to set up.

Ok thx guys.
