Engine Pressure Ratio
The Engine Pressure Ratio function allows the Elite ECU to more accurately calculate the efficiency of the engine. Calculating the MAP / EMAP can show how efficient the engine is at moving air from the inlet to the exhaust, and calculating the MAP / Barometric can show how efficient the engine is at moving relative to Barometric Pressure. The Engine Pressure Ratio is then used as the Load axis for your tuning tables
Pressure Ratio Tab
Ratio Source
Select the secondary pressure source used to calculate the Engine Pressure Ratio
MAP / EMAP
The Engine Pressure Ratio is calculated with the normal intake MAP Sensor and an Exhaust Manifold Pressure Sensor. An EMAP Sensor is required and must be configured separately.
MAP / Barometric
The Engine Pressure Ratio will be calculated with the normal intake MAP Sensor and a Barometric Pressure Sensor. A Baro Sensor is required and must be configured separately.
Display Min
The lowest ratio that can be displayed on any gauge in the ESP software.
Display Max
The highest ratio that can be displayed on any gauge in the ESP Software.
