Picture 3 of 3 from Album injection pulse snapshot
I can see the pulse from #1 injection line and then 3 small pulses from the other cylinders and then the big pulse from #1 again. I am getting about 2v p-p directly out the two knock sensors. I have not measured a timing light yet to see what it needs to trigger. At higher speeds the noise floor becomes a concern. Looks like the $50 store brought pickup might be worth the money for higher speeds.
x is 100ms
y is 800mv
