Manifold Absolute Pressure (MAP) Sensor
Wiring Tab
Options
Input Type
Select whether the internal Elite MAP Sensor is to be used, or an external MAP Sensor is to be wired to your Elite ECU. (Default = On-board Pressure Sensor)
Analogue Voltage
Selected when an external MAP Sensor is to be wired to the Elite ECU.
On-board Pressure Sensor
Selected when the internal 3.0 Bar MAP Sensor is to be used.
Connections
Manifold Pressure Input
Select an appropriate input to use for the Manifold Pressure Sensor. When an external sensor is to be used, an appropriate AVI (Analogue Voltage Input) should be used. (Default = AVI-9)
Connection Type
AVI
An AVI (Analogue Voltage Input) is suggested.
Pull up
Enables a 1k pull up resistor to 5V.
Typically the pull up should be enabled with any two-wire temperature sensor, and disabled for sensors with their own voltage supply. If the sensor is being shared with another ECU, such as with a piggyback installation with an OEM ECU, then the other ECU will generally include a necessary pull up and this setting should be set to Disabled.
SPI
An SPI (Synchronised Pulsed Input) can be used where there are no available AVIs.
Sensor Type
Set to Hall Effect for all analogue inputs
Pull up
Enables a weak 10k pull up resistor to 5V.
Typically the pull up should be enabled with any two-wire temperature sensor, and disabled for sensors with their own voltage supply. If the sensor is being shared with another ECU, such as with a piggyback installation with an OEM ECU, then the other ECU will generally include a necessary pull up and this setting should be set to Disabled.
A MAP sensor is powered by 5V+ so the pullup should be set to DISABLED.
Display Tab
Warning Maximum
Sets the pressure such that if it goes above this, any gauge displaying the Manifold Pressure will begin flashing red.
Display Minimum
Sets the minimum pressure that the Manifold Pressure gauge can display. This does not affect the reading of the sensor, only what can be displayed.
Display Maximum
Sets the maximum pressure that the Manifold Pressure gauge can display. This does not affect the reading of the sensor, only what can be displayed.
Calibration Tab
Active only when the Input Type has been set to Analogue Voltage. This allows calibrations for Manifold Pressure Sensors to be loaded or saved. A number of calibrations come pre-installed with the ESP Software package. If your sensor is not listed, a custom calibration can be created with the data provided by the sensor manufacturer.
From the image below:
*1 – Selecting this yellow Open icon will allow the loading of a pre-configured calibration file.
*2 – Selecting this blue Disk icon will allow the saving of your custom calibration file.
Diagnostics Tab
The settings in this tab allow limits to be set for the detection of either fault conditions, or conditions that could be considered to cause engine damage related to the Manifold Pressure Sensor.
Raw Min
Only available when the Input Type has been set to Analogue Voltage. When enabled, this allows for the error code P0107 to be set when the voltage is below the set amount. This is used to detect a short or disconnection with the wiring. If the Engine Protection function is active a DTC Severity level can be selected for this condition if desired. (Default = Disabled)
Raw Max
Only available when the Input Type has been set to Analogue Voltage. When enabled, this allows for the error code P0108 to be set when the voltage is above the set amount. This is used to detect a short or disconnection with the wiring. If the Engine Protection function is active a DTC Severity level can be selected for this condition if desired. (Default = Disabled)
Operating Min
When enabled, this allows for the error code P0105 to be set when the Manifold Pressure falls below the set amount. If the Engine Protection function is active a DTC Severity level can be selected for this condition if desired. (Default = Disabled)
Operating Max
When enabled, this allows for the error code P0106 to be set when the Manifold Pressure exceeds the set amount. If the Engine Protection function is active a DTC Severity level can be selected for this condition if desired. (Default = Disabled)
