Exhaust Gas Temperature Sensors
Up to 12 Exhaust Gas Temperature (EGT) Sensors may be used with various Elite series ECUs. These can be used for datalogging, engine protection, or engine tuning purposes. A common use for EGT input is to allow individual cylinder monitoring and tuning. Haltech has available 2 channel and 4 channel (TCA2 and TCA4) boxes that communicate to the Elite ECU via CAN. These are the simplest way to connect EGTs to your ECU and do not use up existing wiring input.

Wiring Tab
Options
Input Type
Select the type of EGT Sensor to be connected.
Analogue Voltage
Selected when an aftermarket EGT amplifier box with analogue outputs is to be wired into the Elite ECU. This will require an Analogue Voltage Input (AVI) to be used and configured.
Thermocouple Type K
Selected when Haltech CAN TCA2 or TCA4 boxes are being used for thermocouple inputs.
Connections
Exhaust Gas Temperature Input
Select an appropriate input to use for the EGT Sensor. An AVI (Analogue Voltage Input) should be used when Analogue Voltage is set as the Input Type. When a Haltech CAN TCA2 or TCA4 box is to be used, this device must be enabled in the Devices section of the Main Setup and the desired TCA Input should then be selected.
Display Tab
Warning Minimum
When the EGT reads below this amount, any EGT items on the ESP software will flash Red as a warning of low EGT.
Warning Maximum
When the EGT reads above this amount, any EGT items on the ESP software will flash Red as a warning of high EGT.
Display Minimum
Sets the minimum temperature that any EGT gauge can display. This does not affect the reading of the sensor, only what can be displayed.
Display Maximum
Sets the maximum temperature that any EGT gauge can display. This does not affect the reading of the sensor, only what can be displayed.
Calibration Tab
Available only when the Input Type is set to Analogue Voltage. The calibration data from the aftermarket EGT box should be entered on this page.
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 the set for the detection of either fault conditions, or conditions that could be considered to cause engine damage related to the EGT Sensor.
Raw Min
Available only when the Input Type is set to Analogue Voltage. When enabled, this allows for the error code P0545 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
Available only when the Input Type is set to Analogue Voltage. When enabled, this allows for the error code P0546 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 Max
When enabled, this allows for the error code P1321 to be set when the EGT is above the set amount. If the Engine Protection function is active a DTC Severity level can be selected for this condition if desired. (Default = Disabled)
