Bought a Power Vision, what is VE?

 

Quick google search...off dynojet.com

What are VE tables?
VE or Volumetric Efficiency is a measurement in percentage of efficiency that an engine can move the air/fuel into and out of the cylinder at various rpm and throttle positions (or manifold absolute pressure, MAP). This table is influenced by the engine displacement, camshaft, head design, exhaust, and air filter. In theory a value of 100 would equal the volume of the cylinder, but efficient design allows values greater than this. The maximum allowed value in any cell is 127.5. To increase fuel make the values larger, to decrease fuel make the values smaller.

 

Thank you so much.
