Is there a speed sensor input example for Labview?

While it probably has no impact on the system as you are using it, the "Gear Tooth Sensor" mode is not likely what you want. Read the context help on that mode. It is meant to allow bi-directional counting based on the length of the pulse. This behavior was available from gear-tooth sensors provided in the kit years ago. If you happen to be near the magic number for your pulse length, you could generate glitches in your speed measurement as you "reverse directions". You would be best served selecting Up/Down counter mode and only configuring and connecting the "Up" channel.

Thanks for the info Joe, we will change it up to the up/down mode, don't need any anomalies to pop up in competition.

I noticed I did not link to the TBH code posted by 123 last year, here is the link in case someone is searching this out later.
