The small hole gives a cleaner waveform . On many map sensors in boosted cars we use a restrictor of .035 to stabilize choppy map signal cause map hose,intake manifold design,etc. Same principal here.
@mandytuning Excellent! I figured the Rotkee ones are made for a transducer and probably had a reason I wasn't aware of, whereas the ones that came with it seem re purposed. Thanks for the insight!
@@BackalleydiagnosticsThat is correct. Pressure has no problem with small holes...flow does...kinda like a wire. Voltage has no problem passing, amperage does get limited. Actually with the pressure transducer the less air mass you have between the testing point (cilinder head) and the sensor itself, the better. The air has inertia and the more air you have the more acts like an accumulator and distorts the wave form accuracy. If you check the rotkee pressure sensor page they suggest you put the least amount of tubing when scoping. Ideally you'd screw the sensor directly into the head. The setup you've made is good for fluids let's say because fluids are not affected by length. Good to know the thread measures tho... Thank you!
