Make sure that the units agree between the pids in these places:
- scantool Data tab (edit these on PIDs tab by rightclick->Metric/Imperial);
- tunetool table axis (edit these by going Edit->Configure Display Units);
Check also this:
In tunetool, go Edit->Properties->Display and check that fuel units are not Lambda.
I like to use these units: VE units g*K/kPa and fuel units EQ.
