I need some assistance tuning a cammed OBD 1 LT4 (was OBD II) for emissions. I have been attempting to lean out the idle by altering the O2 voltage. I have had some success but believe I am limited by the O2 lower threshold. I don't know the address of the table for the lower threshold (if it actually does exists like other pcms). If I enter any value below about 300 mv it gets richer.

I am looking for the following addresses and characteristics (multiplier) for the following tables in the $EE bin. An XDF definition with the following tables would be even better.

Fast O2 Rich/Lean Threshhold at Idle (I can access this one via tuner cat, but not tuner pro. Don't really need it but would be nice)
Upper Zero Error Ref Slow O2 R/L at Idle
Lower Zero Error Ref Slow O2 R/L at Idle (this is the one I really need I believe).

Any help would be greatly appreciated!!!
