Speed Density

THE Speed Density (SD) feature changes the way the engine load is calculated.

When SD mode is activated the ECU will disregard the MAF sensor reading and will instead calculate mass air-flow based on engine speed, manifold pressure and air temperature, allowing the MAF sensor to be removed and a larger intake to be installed.

Speed Density can be toggled in any Map Switch mode and a hybrid MAF and Speed Density system can be implemented to enhance the accuracy of readings at low speed and provide maximum calibration at high power outputs. A range of activation options is available for engine speed, mass air-flow and manifold pressure.

This video tutorial shows the setup and tuning of the speed density system for RaceROM.

To view the other available RaceROM Features, please use the menu to the right entitled RaceROM Features.
