Choosing PIDs to log

Postby Hexadecimal » Fri Mar 08, 2019 5:51 am

If I want to change what PIDs are logged to I just edit this in the OBD.h file for the ONE+ ?

PID_POLLING_INFO obdData[]= {
{PID_SPEED, 1},
{PID_RPM, 1},
{PID_THROTTLE, 1},
{PID_ENGINE_LOAD, 1},
{PID_FUEL_PRESSURE, 2},
{PID_TIMING_ADVANCE, 2},
{PID_COOLANT_TEMP, 3},
{PID_INTAKE_TEMP, 3},
};

Hi,
I am looking for the same thing.
Have you found the solution ?
Thanks

Yup. Be sure to keep those 3 tiers and also keep them sorted by tier number.
The idea is that you want lower numbers for PIDs that change quickly and higher numbers for slower PIDs: the engine rpm changes more often than the coolant temperature, for example.
