Injection mode
There are three working modes available:
1) Batch fire output 1 – in this mode, all injectors (not more than 4) are connected to the Power Out #1
output,
2) Batch fire output 1& 2 – in this mode, the injectors are connected to both power outputs and are working
simultaneously,
3) Bank Fire – in this mode, the injectors are connected to both power outputs and are working in turns.
After connecting the injectors to the DET3 device, the factory installed ECU may turn into the limp mode
because of the lack of load in the outputs controlling the injectors. To solve this problem you should perform the
injectors’ „emulation” with the help of resistors. In most cases, it should be enough to connect the 10K/0.25W
resistors into the place of each injector. Unfortunately, certain ECU output drivers cannot be “cheated “ like that.
In such case, you should use resistors of the similar resistance to the injectors, but their power must be
significantly higher than 0.25W. You choose the resistor’s power according to the pattern bellow:
P = U*U/R
where,
P – the calculated resistor’s power,
U – power voltage (usually 13,5V)
R – injector’s resistance
And so, the 14Ohm injector’s power should equal at least 13,5*13,5/14 = 13W. On the market, there are
available resistors of the following power: 10W, 15W, 20W, 25W, 50W, so in this case it is enough to use the
15W or 20W resistor. It should be underlined that this resistors will emit a significant amount of heat. The
resistor’s power may be greater that the calculated one.
