Is this normal ? Am I really that off on my A/F ratio?

Bonus question: Anyone know the gauge settings for bank 1 short and long term fuel trims? I'm not getting any readings with the settings I've used.
If your ECU doesn't have the front AFR sensor (uses standard O2 sensors), then all bets are off. Regular O2 sensors will basically only be able to tell you rich or lean, but not by how much.

I use the following for STFT and LTFT on my '99 California 4Runner:

TXD: 686AF10106
RFX: 044105060000
RXD: 2808
MTH: 00C80100FF9C
NAM: ST%

TXD: 686AF10107
RFX: 044105070000
RXD: 2808
MTH: 00C80100FF9C
NAM: LT%
