    The tach is important. Go out and get it up to cruising speed in D and then drop it into Sport. You will soon see.

    You can turn the tachometer on and off from the Home screen, go to Settings->System->Tachometer Settings. From here you can toggle it on and off.

    If you notice all the gauges "sweep" on power up. This is a pretty common thing with many computer dashes. It actually has a name, its a "POST" test. Yes, we all know "post" comes from the Latin "post" as in "after" but in this case its a acronym for Power On Self Test. It shows that all the segments of the board and their drivers are working. Oh, and it looks cool too. But actually its a build in diagnostic test that can be very helpful if there is a problem. So for a computer POST comes first, not after.

    Tachs are very useful, especially in a vehicle where its hard to hear the engine at times. It lets you know if its lugging, if its over revving, if the transmission is slipping, etc. But if you have no use for it, shut it down using the instructions in the manual.

    OH, and its been a VERY long time since any vehicle had a cable driven tach or speedo. A very long time! In the field we were so happy to see those damn cables go away back thirty years or more ago. They were a PITA.

    The gauge sweep at startup can be kind of a PITA. I have another car that does it, and it prevents me from seeing things like oil pressure at startup. I end up using an OBDII sensor if I want to see that kind of info within 5 seconds of starting the engine.

    It does look cool, though. Moreso on a full set of analog gauges than on the CR-V's digital ones.

    I much enjoy my 2017 CRV digital tachometer's post test. Thanks, "master" Hans471 for your meaningful explanation to everybody in this room.
