■ Function2
■Ignition timing adjustment
For EASY mode, advance and retard can be input for stock ignition timing.
For EXPERT mode, the entered value (crank angle before top dead center) will be the ignition timing.
For the EXPERT mode, the“engine temperature ignition timing correction function”that adjusts the effect of changing the vaporization time and combustion time and affecting the ignition timing when the engine temperature becomes too high can be adjusted.
■Invalid injection time correction
There is some time lag before the injector is energized and injects fuel. This is called the“invalid injection time”
The“invalid injection time”changes depending on the voltage, so if the supplied voltage changes due to battery or alternator condition,injection command to the actual injection changes, and the injection amount will also change. In order to prevent such a problem, it is possible to set the condition to be constant by applying correction.
■Engine temperature compensation
PGM-FI Injects more fuel than the value of the injection MAP when the engine temperature is lower than the appropriate temperature according to the input value from the oil temperature sensor, and warms up the engine faster. etc.
■Intake air temperature compensation setting
Since the density of air changes depending on the temperature, the air-fuel ratio change due to the intake temperature is compensated.
