Does the ODBII LT1 pcm have a "commanded AFR" PID? I have autotap and it includes this parameter in its complete list of supported GM parameters, but I have never had the parameter recognized when i plug into my 97 LT1.

Is this a problem with autotap, or do LT1s just not support that particular GM pid?

 

I have autoxray and it reads "Commanded AFR" When its is open loop it fluctuates between 12 and 14 AFR. When it is closed loop it always says 14.7.

I also have a wideband and a guage and the open loop commanded AFR's are quite a bit different.
