Post subject:  Measuring Volumetric Efficiency using Scan data
A Neat Online Tool provided by OTC to plug in data and calculate Volumetric Efficiency using scan data for an engine:

VOLUMETRIC EFFICIENCY CALCULATOR
https://www.otctools.com/ve

VE should be between 75-90%
Anything lower could indicate worn rocker rollers or cam lobes. :cry:

IMPORTANT - the readings must be in the following format
- Degrees Fahrenheit
- RPM
- MAF in gs
- Engine size in liters
An acceptable VE range is between 75% to 90%.
When IAT reads in °C, the PID will have to be converted to °F.
Converting °C to °F: (°C x 1.8) + 32 = °F

I used to do this using Torque Pro. They have a PID for it built in and as long as you enter the correct displacement(2776 cc) under the vehicle details, it should be pretty good. Mine would be near 90 at low RPM, but up top it would doo doo the bed. This engine does not breath well at all beyond 3000 rpm.
