OBDLink Custom PIDs
Posted: Tue May 29, 2018 11:38 am
Using the latest version of the OBDLink MX ap it is now possible to enter Unit values.
If you have Metric selected in the settings then you can enter a "C" for a Metric Unit reading and it will show in the Trans Temp.
The same with pressures etc.
Aternator Current Clamp Amps
Min Value: 0
Max Value: 200
Header: 7E0
Mode: 22
PID: D113
Equation: ((A*256)+B)/20 If you are getting figures like 500 amps then change equation to ((A*256)+B)/200
This gives a % reading of the battery state of charge for the MAIN battery only.
