O2 sensors

General General RealDash discussion

Hi Jani,

I just want to understand something related to O2 sensors written in OBD XML file. I have only one in front of the catalytic converter and one downstream.
A- Should I update my XML sheet with only 2 sensors?

B- Why you link “in the example XML sheet” Target ID#0 to many inputs?

EX:


C- I can read Fuel-Air commanded equivalence ratio PID(0144), should I send this value to target “ID 0” - AFR? please advise.

Regards

Different vehicles send AFR in different PIDs. For that reason, RealDash default XML attempts to read them all and gets the data from which is active/supported. It makes sense to modify this to fit your vehicle exactly.
