    a Narrowband oxygen sensor(what you have) has a range of .1V-.9V(aka 100-900mV).
    Stoichiometric is .450-.5V whichis key to catalytic converter efficiency.

    Under WOT, you're AFR's should be 12.5-13.5 on a stock car, and somwhere in the range of .650-.750V reading on the Oxygen sensors.

    Yes .85 would be where you want to be at WOT, this is in the low 12's to high 11 range.

    great.

    i got an SAFC Neo to try and adjust the 5k-up range on my PC-16 setup.

    i don't have a wideband yet.

    here is the lean top-end of the PC-16 the day i got it installed.

    this is after the FPR adjust to richen the top end.
