Stage I & Stage II OBD

[Kirby]

# Bar Boost comment:

especially since certain OBD functions were shut off to make it easier for you to increase performance if you so desire.
It would be of interest to know specifically, which diagnostic functions are removed or turned off in the PCM for the Stage I and Stage II kits. Facts would be easier to digest than conjecture.

The graphics are missing, but this is a snapshot of the Telemetry OBD monitoring readings.

All those will show up fine, except maybe downstream oxygen sensor (bank 1 sensor 2). And I stress maybe. The fuel trim of 100% doesn't seem right, it should be less than the upstream value (0.075 volts versus 0.605) - so maybe that telemetry thing is already giving out faulty info.

The one OBD monitor that I know is shut off with Staged kits is the P1188 code (part throttle TIP overboost). This keeps us from getting the EO number. Trying to find out what else is shut off, if anything.

This is the California list (all that the state will ever require of my PT for as long as I own it), so maybe we can squeek through anyway. Thanks for all your help!
