RPM Signal reading wrong

I'm using a V1 UART adapter and when using obd.readPID(PID_RPM, value) I'm getting a completely wrong value. My car idles at roughly 700rpm and using the freematics adapter and code library it reads roughly 2,300rpm so I'm guessing the library code isn't set up correctly for two byte hex data? Has anyone else had the same issue and solved it?
