Hi there once again. I been reading an old post from Ben Martins. https://www.picoauto.com/library/case-studies/lack-of-power-diagnostic-process In this example he shows a waveform from the crank sensor and a frequency to plot accel and decel. I've come across similar waveforms on vehicles but I don...

I tried the rulers to see if that would work and after plugging in a range i'm left with no trace at a...

Measuring Timing using injector pulses

Hi everyone! I work on diesel engines and was wondering about using injector pulses to determine engine timing or at least a change in timing. Is there any posts related to this already or is there someone who has some info on this? I also understand this may be difficult as today's engines using mu...
