18.7 Engine temperature compensation
This compensation is applied based on the engine temperature
sensor, which, in water-cooled cars, must be at the cylinder head reading the
water temperature, and in air-cooled engines, must be reading the oil
temperature. Compensations based on engine temperature are only available
when the sensor is connected to the injection system.
18.8 Intake air temperature compensation
This compensation is applied based on the air temperature sensor
placed in the intake manifold, and it is only available when the sensor is
connected to the injection system. This compensation mode is used to
automatically adapt the injection to different temperatures of the air taken by
the engine. In turbocharged engines, it is of great importance, because when
the system is pressurized, the temperature rises immediately to very high
numbers. In cars with intercooler, the ideal mixture can be used from
intercooler inefficiency situations (low speed) on.
18.9 Battery voltage compensation
With lower battery voltages the injectors takes a longer time to open
and to close. This table is used to compensate this variation.
Fuel injectors with a high flow rate usually operate with minimum
injection time at idle speed and are the ones most affected by a battery
voltage drop.
18.10 MAP / TPS compensation
This table changes according to the main map configuration (MAP or TPS). When the main fuel table is setup by
MAP, this table is a compensation by TPS. When the main fuel table is setup by TPS, this compensation is by MAP.
18.11 Prime cranking pulse
This feature improves the engine start by injecting fuel when any crank trigger tooth is detected, just like OEM
parameter injection times.
Select which fuel bank you want to use for prime pulse and setup its table by engine temperature.
