Ioniq and Niro PID RPM_Unknown.

Hi all.

On the original Ioniq HEV PIDs there are one RPM_unknown. After some testing with my Niro HEV I think that sensor is the HSG motor rpms. The HSG (Hybrid Starter Generator) in the HEV and PHEV models is an electric motor that start the engine and charges batteries from engine power.

Here are some specs:

PID is:
000_RPM Unknown Unknown RPM 2101 (Signed(BD)*256))+BE -10100 10100 rpm 7E4

Min and max values should be 0 and 12000

Without any technical information about this I'm very confident with this PID.

Great, more people testing more confidence.
