Injectors
The DET3 device has 2 power outputs with the 5A load each. Because of this, we can connect to each of them 4
high-resistance injectors or two low-resistance injectors with the resistor limiting the current (6Ohm, 25W+).
There are three ways of connecting the injectors:
1) All injectors connected to one power output, working in the „Batch Fire” mode
2) Injectors are connected to both power outputs, working in the „Batch Fire”. This mode is used in case of
engines with the number of cylinders higher than 4.
3) Injectors connected to both power outputs, working in the „Bank Fire”
In case of the “Bank fire” mode, for the 4 cylinder engine we should connect the injectors in pairs from cylinder
working in the opposite cycle phase. And so, for the engine with the ignition order 1-3-4-2, we should connect
injectors in pairs from cylinders 1 - 4 and 3 - 2.
