Fuel Temperature Sensor
A Fuel Temperature Sensor can be used with your Elite ECU for datalogging, overall safety and Engine Protection purposes. Temperature sensors are typically two wire sensors; a signal wire that is connected to an AVI, and a signal ground wire.

Wiring Tab
Options
Input Type
Select the type of Fuel Temperature Sensor to be connected.
Analogue Voltage
Selected when the supplied calibration data for the sensor is in voltage. This will require an Analogue Voltage Input (AVI) to be used and configured.
Analogue Resistance
Selected when the supplied calibration data for the sensor is in resistance. This will require an Analogue Voltage Input (AVI) to be used and configured.
Thermocouple Type K
Selected when a thermocouple input is to be used. Typically with a Haltech Thermo Couple Adapter (TCA2 or TCA4).
Connections
Fuel Temperature Input
Select an appropriate input to use for the Fuel Temperature 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.
Please note pre installed temperature calibrations will require adjustment if used with an SPI.
Calibration Tab
This allows calibrations for a Fuel Temperature 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 Fuel Temperature Sensor reads below this amount, any relevant items on the ESP software will flash Red as a warning of low temperature.
Warning Maximum
When the Fuel Temperature Sensors reads above this amount, any relevant items on the ESP software will flash Red as a warning of high temperature.
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 Fuel Temperature.
Temperature Raw Min
When enabled, this allows for the error code P0182 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)
Temperature Raw Max
When enabled, this allows for the error code P0183 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)
