Here is more PCM data to analyze and follow how using a OBD scanner pinpoints problems without ever seeing the car.

Owner had the above mods done and then some so called pro tuner tune the PCM

Car ran quite badly. Review the mods installed and then the performance as looking at the torque values recorded.

Notice in top graph if you do not analyze all the data as in this case you would not see any real issue

Now look at the 2nd graph and you notice PCM never goes into close loop, the fuel trims show no values all due to one O2 not functional

Now compare both front O2 sensors and you see the right (B2) O2 never reports over or under 450 mvolts.

By seeing they I then called the owner and the shop he went to to find out the problems and told then what the scanner data had told me and shop looked to find both front O2s were plugged into the other sides wiring to PCM.
