Ok i got the Lambdas working! , one lambda is PID 34 and the other 38.

I just made it 'long int' in the source file, and it seems to be working great!

result = (long int)getLargeValue(data) * 200 / 65536;
break;

I still cant get commanded air fuel equiv ratio to work though...but il keep at it ...

Thanks so much! Really appreciate it!

Unfortunately its still not working, my car must have a random pid address or something.

I've tried oxygen sensor voltages, oxygen fuel–air equivalence ratio, demanded fuel–air equivalence ratio and none of them are returning any values. Only short term and ...

Hello,

How do I retrieve a PID's data that isnt a float?

For example i want the 'Fuel–Air Equivalence Ratio' which returns a value between 0 and 2.
But obviously its returning it as a int, so i only get values 0 and 1 lol.

Please help, this is the main PID that i need.

Thanks!

Hi there,

The obd adapter is working great, no issues and update speed is decent!

Im wanting to add a few extra PID's, basically only fueling. Requested lambda and actual lambda. So if you can guide me on the right track it would be awsome.

I started with defining the PID in the header file ...

Thank you!

Hello, im having a blast with this obd reader, no issues yet and reading pids non stop! Really impressed!

Sorry for the noob question, but how do i use getVoltage()?

Hope someone can help!

Thanks!
