Relative compression test with injectors 1-3 and 4-6 disconnected at the valve cover.

Injector #1 signal used as a reference for cylinder ID.

I think what you’re doing is awesome.

Are you a technician by trade?

I started in automotive but have transitioned to heavy equipment and haven’t looked back.

I have a 4ch scope that’s pretty nice but nowhere near a Pico.

Thanks!

I am retired now, but during my working career, I worked as a machinist, diesel mechanic, and electrician.

Also, a fair amount of time working around electronics, uninterruptible power supplies, circuit board repairs, and troubleshooting, etc.

It’s been a while, thought I would add some additional reference waveforms taken with a Pico WPS500X pressure transducer.

Exhaust Pressure Pulse:

Coolant tank Pressure Pulse:

Crankcase Pressure Pulse:

Automotive Test Solutions also makes an excellent oscilloscope.

I think Bernie Thompson is one of the world's greatest automotive minds.
