The Fuel Density Temperature Coefficient setting is used to specify how the density of the fuel used changes with temperature. The fuel density temperature coefficient is required as part of the ECUs fuel equation.

Note: This must be correctly set irrespective of if a fuel temperature sensor is used. Fuel temperature density correction will not be applied unless a fuel temperature sensor is fitted and correctly configured.

 

Fuel Density Temperature Coefficients by Fuel type

Fuel Type

FDTC (1/deg C)

Petrol (Gasoline)

Note: This setting is only used when the Fuel Equation Mode is set to Modelled or Modelled - Multi Fuel.
