Hi folks, new here, be nice..
I fitted an aftermarket 3-cyl tacho today and the revs showing look a bit low so the very first thing I need to know is what the revs are supposed to be for a few given speeds.

The user's manual only shows idling speed (which is showing correctly)..

Could someone with a tacho-fitted car please post just one or two speeds and corresponding rpm as observed while driving (carefully!)? 100kph would be a great benchmark because it's close enough to 60mph.

Alternatively, some people are probably better at web searching than I - and somewhere all this is documented..

Kind regards, Steve
