Most (if not all) Live Data logging parameters should be described in your Predator or Trinity manual. However, with new CROM software revisions there may be additional parameters added that do not appear in your original manual. This help page should help you determine the meaning of the parameter.
Depending upon what Predator or Trinity part number you have, some parameters have verbose text descriptions and some parameters have only a brief acronym. For the later case, the following table will help you determine what most of these acronyms represent.
Example 1: IN MAN EGR MASS
Intake Manifold Exhause Gas Recirculator Mass
Example 2: T CYL VE MOD
Cylinder Temperature Volumetric Efficiency Model
