Service manual

ATTENTION!
Exceeding the outputs’ load limit (5A) will lead to the damage of the power outputs,
what may cause the permanent opening of the connected injectors !
ATTENTION!
The line powering the injectors (+12V) should be protected with the suitable fuse and
the powering should take place only with the ignition being turned on !
ATTENTION!
The ground used to control the injectors (Power ground) should be a connected by
different wire than the one used to power the device (Ground pin 10).
The description of the parameters of the injectors’ configuration
The options of injectors’ configuration are available from the SA Fuel Implant/Injectors menu.
Injector Size
Injectors’ flow in cm
3
/min.
Injector opening time
The time required to open the injector in milliseconds, for the working
pressure and the powering voltage 13.5V. Usually, this is the value in the
range of 0.6-1.2ms.
Battery correction
The linear correction of injectors’ opening time, depending on the voltage
in the electric installation of the car, with regard to the voltage 13.5V.
Together with the decrease of the voltage, the opening time of injectors is extended.
Injection divider
This value stands for the frequency of fuel injection compared to the crank shaft turn.
The engine’s cycle (720 degrees of the crankshafts’ turn) is divided into 4 parts (every 180 degrees).
Divider which equals 1 in the Batch Fire mode means that all fuel injectors will be started every 180 degrees. In
case the injectors work in the Bank Fire mode, this will mean that each bank will inject the fuel once per 180
degrees of crank shaft turns.
In case it works in the Batch Fire mode, it is advised to use the divider which equals 2 or 4. In case it works in
the Bank Fire mode, it is advised to use the divider which equals 1or 2.
