Hi!
I’ve just started using the Torque Pro app and I haven’t been so lucky as to get the current gear indicator/value as the manufacturer of my motorcycle used a different PID for it.

But I do have information on RPM and velocity and I’d like to build an app to make a cool looking display of it integrated with a map. Anyway, what I’d like to know is, is there a way to use the RPM pid and speed PID into one gauge in the torque pro app?

RPM formula is ((A*256)+b)/4

Formula for gear ratio:

Gear ratio = (RPM*(3.14*circumference of tyre))/speed

End Quote.

Use equation like the following for your
Gear Ratio custom pid.

([0c]*3.14*circumference of tire)/[0d]

or by long name

(Val{Engine RPM}*3.14*circumference of tire)/Val{Speed (OBD)}

The long names must match exactly… since I’m trying to
do this from memory the names are probably off.

This assumes your motorcycle is returning [0c] and [0d]…
and equation is correct. (pi*diameter, units)?
