VE-Based Speed Density
THE new volumetric efficiency (VE)-based Speed Density feature changes the way in which the engine load is calculated.
When Speed Density mode is activated the ECU will disregard the MAF sensor reading and will instead calculate mass air-flow based on the engine speed, manifold pressure and air temperature
A hybrid MAF and Speed Density system can also be implemented to aid accurate readings at low speed and provide maximum calibration at high power levels. A range of hybrid mode activation options are available for engine speed, mass air-flow or manifold pressure along with calculated charge or dedicated charge-air temperature compensation factors.
Speed Density can be toggled in any Map Switch modes, and a hybrid MAF and Speed Density system can be implemented to aid accurate readings at low speed and provide maximum calibration at high power levels. A range of activation options are available for engine speed, mass air-flow or manifold pressure.


The following video tutorial shows the setup and tuning of the Speed Density system for RaceROM
