Actually there is a Class 2 PID that techncially COULD be translated by the Interceptor, (but it's NOT)This value IS availabe on the LSJ when using a TECH2 scan tool.
It's actually a "calculated" PID that GM uses that is based on current fuel delivery and existing engine conditions. (Not an actual reading of anything that could be directly equating to actual AFR like EGT or Exhaust Oxygen making it OK for a "trip computer" but not at all accurate enough for tuning) For instance this PID assumes your fuel pressure is OK, but if it's NOT what it is telling you will not be a true reflection of your actual AFR.
And since the LSJ does not use a wideband O2 sensor, it's measurement is essentially useless to anyone looking for "tuning" by the numbers. My advice, purchase a WB02 with controller andgage/digital readout.
