    What's the Tach Incremental?

    18 PX with the 3 analog gauges vs 21 PX with the single digital gauge cluster.

    What are the increments on the tach display?
    My 18 displays every 10-20 rpm on the top. 8010, 8020, 8030 etc.
    My 21 displays only by the 100 rpm. It goes from 8000 to 8100 and the ECU will close it down some and the display goes to 8000 again. Nothing in between. That's crazy, what's up?

    Both seem to show the same 50 rpm increments down at lower rpm.

    I think the 100 rpm increments are ridiculous for a digital tach. It bothers me on my 21 PX.

    I could have sworn I saw a "40" at the end of my tach on occasion? I mean like an 8040? I'm old though so maybe I'm misremembering? So I thought the increment was at least 20?

    That is the case on my 18. Your 19 is the first year of the new style single display. Maybe it reads like my 18, but the 21 appears to be in 100s on the top. That is pathetic for a digital tach on a performance machine.

    That's kinda shitty, saw a video of the color cluster and it also does 100 rpm increments.

    Your 18 will display in 50s down low, but up top, it should display 10/20.

    Looked at a video of CAN-AM Spyder with the color cluster and it also does 100 increments Kinda crappy for fine tuning and figuring out performance gains, logging will become more important.

    LOL...fine tuning? 500 rpm increments is fine tuning. The exception is 5750, 6750, 7750 (250) , then 200 rpm increments above 8200.

    I meant something in this scenario...

    Say your ski is running 8000 RPM and you add some minor mod and now RPM is 8100 what did you gain? Assuming they round up at 50, with 100 increments you don't even know if the original RPM was 8000, it could have been 7950 or 8040. Maybe you're really now at 8140 or 8050, no way to tell without logging.

    There's a point where only 1 RPM will be the difference between showing 8000 vs showing 8100.
