Gearbox Line Pressure Sensor
A Gearbox Line Pressure Sensor can be used with your Elite ECU for datalogging and for Engine Protection purposes. A Gearbox Line Pressure Sensor is a powered sensor that typically has three wires; a 5V+ power wire, a signal wire to the Elite ECU, and a Signal Ground.

Connections
Gearbox Line Pressure Input
Select an appropriate input to use for the Gearbox Line Pressure Sensor. An AVI (Analogue Voltage Input) should be used.
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.
Calibration Tab
This allows calibrations for a Gearbox Line Pressure Sensor 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 above:
1 – Selecting the yellow Open icon on the top left will allow the loading of a pre-configured calibration file.
2 – Selecting the blue Disk icon next to the open icon will allow the saving of your custom calibration file.
Display Tab
Warning Minimum
When the Gearbox Line Pressure reads below this amount, any relevant items on the ESP software will flash Red as a warning of low pressure.
Warning Maximum
When the Gearbox Line Pressure reads above this amount, any relevant items on the ESP software will flash Red as a warning of high pressure.
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.
Raw Min
When enabled, this allows for the error code P0842 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
When enabled, this allows for the error code P0843 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 allows detection of Gearbox Line Pressure conditions that could cause concern. When the Gearbox Line Pressure is below this amount it will activate the DTC P0841. 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 allows detection of Gearbox Line Pressure conditions that could cause concern. When the Gearbox Line Pressure exceeds this amount it will activate the DTC P0844. If the Engine Protection function is active a DTC Severity level can be selected for this condition if desired. (Default = Disabled)
