It's been about 15 years since I've done any serious tuning on my Firebird and I'm rusty. I'm wanting to check my actual AFR. I have a "Calc.AFR" pid selection that I've used in the past loaded into the black box and the LM-1 connected to it. But I can only find commanded AFR in the log file.
Can anyone share the proper pids needed to log actual AFR data with the LM-1 with me?

Are you using the 0-5V input or serial input?

Forgive my stupidity, but I think I'm using the 0-5v input. It's the one that connects to the V7 black box.

Are you using V7.5 or V8?

If you have the 5V and ground input into the Interface you have to select the correct wideband in the PIDs.
As well as commanded AFR and BEN.
