I guess I don't have any knowledge of either of these you mentioned. I am referring to my GMC Sonoma 2.2L 4 cyl.
Anyway, I just finished building a little fuel injector monitor which I can now use to visually monitor exactly how much time the injectors are injecting fuel. It has 10 LEDs, each one representing an injector ON time of approximately 2.3% of total time.It was very interesting to learn how much a higher gear reduced fuel consumption. I have been driving in too low of a gear climbing hills. I have always thought that pressing the accelerator pedal down further, as required in higher gears, was worse for mileage, but I am surprised to see how that is not quite true.
My LED monitor just converts the pulses from the injectors to a voltage which the LEDs correspond to.
