The ECU only does what you allow it to do on the TEC3R. I can tune by map, engine temp, and air temp, also by TPS. You can also give the computer an authority range for the O2 sensor. Mine is tuned to only change mixtures by 4%. I can change the amount but the better tuned the computer is the less the O2 should have to work. Usually after tuning I turn off the authority range, so if the sensor fails it's not adding or pulling fuel. I will work on air temp tuning now and see where that takes me. Thanks for everyone's help.
