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?

v 7.5

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.
