Flex Fuel sensors
Flex fuel sensors measure the amount of ethanol content in the fuel passing through it. The flex fuel sensor has a pre calibrated signal that is sent from the sensor in a 0-5v voltage indicating which amount of ethanol is present. Capoworks ECU can use this data. The signal circuit carries the ethanol percentage via the frequency signal.
Fuel Level Sensing
The fuel-level input converts an analog sender voltage into a percentage with an eight-point calibration curve. In TunerStudio, open Sensors > Fuel level sensor, assign Input channel, and edit the Fuel Level voltage-to-percentage curve (fuel-level dialog). The curve voltage points must be ascending.
Fuel Pressure Sensors
The firmware provides separate low-pressure and high-pressure fuel sensor inputs. Both use a two-point linear calibration: raw voltage against known pressure at each endpoint (fluid-pressure initialization). Open Sensors > Fuel pressure and assign Fuel low pressure ADC input or Fuel high pressure ADC input, then enter their voltage and pressure points (fuel-pressure dialog).
