Wastegate Valve Position Input(s)
Select an appropriate input to use for the Wastegate Valve Position Sensor(s). An AVI (Analogue Voltage Input) or SPI (Synchronised Pulsed Input) should be used.
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
The calibration can be manually altered by directly entering voltages for 0% and 100% wastegate positions.
This allows calibrations for a Wastegate Valve Position 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.
