Hmm. From all the other lists I've seen, O2b1s2 is 16 in hex, not 1146 or 15. Interesting. PID15 would still be within 00-1f. I can try 15 (M01P15S02R1).
I wondered if that data just wasn't read because rear O2s are not used in my truck. I see some half tons used 8322 OS, and they have P10420 enabled where mine doesn't...but I don't see a place to "turn on" the rear o2 in my BIN.
This weekend I tried moving the pin to the EGR and using that with no luck. Oddly enough, it also scaled perfectly with the speed for some reason... So I went back and noticed my WBO2 MACRO was right underneath the KPH MACRO in the MONITOR MACRO list. It was the 11th entry in the list. Maybe the ELM will only take 10 readings total and it just duplicated the 10th reading for the 11th? I deleted the STFT B1 MACRO and moved the WBO2 MACRO up in the list to see if that makes any difference. I'll find out tomorrow. Either way, I'll switch the wiring back to the o2b1s2 pin when I get a minute and try that out too. I'd really prefer that than killing my EGR.
