Here is a little more on EcuTeK Speed Density and photos directly from their software.

EcuTeK Custom Speed Density Tables

- Speed Density Activation MAF - ECU will use SD Mass Airflow map rather than MAF sensor above this MAF. For hysteresis, top value should be higher than lower value

- Speed Density Activation MAP - ECU will use SD Mass Airflow map rather than MAF sensor above this MAP. For hysteresis, top value should be higher than lower value

- Speed Density Activation RPM - ECU will use SD Mass Airflow map rather than MAF sensor above this RPM. For hysteresis, top value should be higher than lower value

- Speed Density Mass Airflow - Mass airflow derived from RPM and MAP

- Speed Density Temperature Compensation - SD Mass Airflow adjustment based on IAT

- Speed Density Throttle Delta Compensation - Compensate SD based on Throttle Delta and RPM

All tables can be enabled based on:

- Map Mode - In which map mode speed density will be active, available maps are 1,2,3,4

- Thresholds - This will offer the ability to offer a change when Speed Density is active. Active only above/below threshold maps.

Cheers,
