- Adjustable downshift threshold voltage
- Adjustable upshift threshold voltage
The Drenth Gearboxes Switchbox is an analog-to-digital converter which is used in combination with the Drenth Display Unit or a programmable ECU to enable flat-shifting. When a digital output signal is required for setting the ignition cut the Switchbox is used to convert the analogue signal. Because the Switchbox is equipped with two potentiometers, the upshift and downshift threshold levels can be adjusted as desired.
