Hi could please anyone help me?
I have just installed a speeduino V04 board on my Suzuki Vitara 1.6 Throttle body injector and I could not make the injector open while cranking. It is a Low-Z injector with resistor in series to limit the current and it works fine when I go to tunerstudio->hardware test and test the injector.
In this option, the injector opens and closes fine according to the specified duty cycle. Also in this conditions I checked the input signal arriving (ground) to the injector and the noise and signal levels are the same when cranking. However, when I’m cranking the engine, the injector stays closed all the time until I stop cranking. When I stop cranking it opens just a little.
Can anyone help me on this? I’m a newbie in this subject.
I attached my current tune.
