The TORQUE PRO Volumetric Efficiency (Calculated) PID from the PID list just displays “0.00”. I think it has to do with Absolute Barometric Pressure is not available at PID x0033 on my vehicle (2004 F150 5.4L). All other PID necessary for VE calculations work via the Standard and/or Extended Ford PIDs, ( Engine Displacement (5.4 Liters) is in Vehicle Profie. Mass Air Flow, Intake Air Temperature, Engine RPM, all work). I created a Barometric Pressure PID from FORDs x1127 PID that is Barometric Pressure in InHg. I can convert it to proper (kpa) units, but the ‘OBD2 PID Editor’s “Overides PID:” option does not include Barometric Pressure as one that can be overriden.

Am I missing something simple – or any ideas. I have not had success putting together the ‘rather complex’ formula for just creating my own VE calculation.
