Rpm e velocidade

Good evening guys, could someone help me, my car only has a kaline and has a red can with obd2 input, I can already map the signals via wires, it’s just missing speed and rpm, could anyone help me make realdashe recognize pulses?

Just generally, asking for help with such little information probably will not get any attention. Also, in many cases it is next to impossible to help on custom projects remotely.

It is ok to ask for help, but you need to give all the details of your connection type, vehicle etc.
