Gear Detection
The Gear Detection function allows the Elite ECU to know or to calculate which gear the transmission is in either for tuning or datalogging purposes. This can be achieved by a gear position sensor, a gear ratio calculation simply by the use of a vehicle speed sensor and engine RPM, RPM drop with each gear selected, or with a gear switch.

Wiring Tab
Options
Gear Maximum Number
Enter the number of forward driving gears. From 1 to 6 are available.
Gear Detection Type
Select the method used to detect gear position.
Gear Ratio
This method requires the Gear Ratios function to be enabled and configured.
Gear Switch
This method is used with a gear change switch, such as a load sensor, to increment the gear number. A Clutch Switch activation will reset the Gear number back to zero.
Gear Position Sensor
This method is used when there is a sensor on the gearbox that reports a different resistance for each gear selected. This is the only Gear Detection Type that can be used when the Transmission Type is set to Automatic.
RPM Drop
This method is used when only Engine RPM is available, and is used primarily for drag racing where gears will not be downshifted.
CAN Input
This method is used when the Gear Position is transmitted via the vehicle CAN.
Selector Position Enable
Select the method used to detect gear position.
Disabled
Select when there is no Gear Selector Position Signal
Voltage Input
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.
CAN Input
This method is used when the Selector Position is transmitted via the vehicle CAN.
Connections
Gear Switch Input
Available when Gear Switch is set as the Gear Detection Type. Select an AVI or SPI to be used. Gear Switch input requires the Clutch Switch function to also be configured and wired. The Switch On and Switch Off voltages should be entered to suit the switching conditions.
Gear Voltage Input
Available when Gear Position is set as the Gear Detection Type. Select an AVI or SPI to be used.
Selector Position Input
Available when Voltage Input is set as the Selection Position Enable Type. Select an AVI or SPI to 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.
Gear Switch Tab
Available when the Gear Detection Type is set to Gear Switch.
The Gear Switch will activate when the Switch On Voltage amount set in the Wiring Tab has been exceeded and the Gear Number will increase by 1. Another activation of the Gear Switch is only allowed after the Switch Off Voltage has been exceeded.
Gear Switch Reset Time
The amount of time after the Clutch Switch has been activated before the Gear Number will reset to 0.
Clutch Release Time
The amount of time after the clutch switch has been deactivated before the Gear Number will increase from 0 to 1.
Gear Switch Debounce Time
The amount of time after the Gear Number has increased by 1 before another Gear Number increase is allowed.
Gear Position Tab
Available when the Gear Detection Type is set to Gear Position, for both Automatic and Manual Transmission types.
This allows for the Gear Position Sensor calibration to be created. By pressing the Calibrate button with the gear selector in the listed position, the Nominal Voltage value will be filled out automatically with the currently read voltage. This auomatically calibrates each gear position.
