The ZT-2 RPM is reading wayyyy low. I added OBD-II RPM, but doesn't update very often. Not sure if i need to calc it... I used the Yellow CPS feed per this:

I think you're supposed to set up the engine size as a 1 cylinder to have the correct RPM reading. Your RPM reading should have nothing to do with the OBD if you are using the ZT2. Did you buy the ZT2 add on for your Dashdaq?
