5.0 Plug-in Specific Information
5.2 Fuel Model
The ECU can use many combinations of methods to generate the fuel mass output . The
ECU base calibration is supplied using simple but common Speed Density (MAP). There are
many other fuel modelling methods possible to achieve an excellent result. Commonly
modified camshafts, aftermarket air bypass valves, larger turbochargers and modified intake
piping will tend to create unstable Mass Flow Sensor readings so MAP based fuel models
tend to make the process much simpler.
Figure 5.1. Fuel Model Setup
Press F1 when you have this setting selected for more detailed help on each Fuel Model.
When MAF is selected the Secondary Load table can be used to scale the MAF if required.
The factory calibration should provide good initial air mass calculations but it will be
common to modify the intake and therefore this will require re calibration of the MAF
meters. This table will need to be switched ON. To do this select Fuel Menu-> Fuel Table
Control -> Secondary Load Table. Set to a value of 12 as shown in Figure 5.2.
