Understanding running compression waveforms

[@SimplyDiagnostics]

Great, concise video showing the fundamentals of in cylinder pressure diagnosis. 6 yrs old and as useful in 2018 as it was in 2012

great study,now demonstrate running compression sync to ignition timing to confirm ecm timing advance.

Many thanks. One question; How to measure valve overlap?

[@Dongdang-fc2mb]

Very useful information but unfortunately you're bringing some kind of bright light on the screen that makes the video vision unable to follow. If you kept the video away, it would've been a great one

What was the point of looking at the MAF while determining max bar output of the cylinder at WOT?

Picoautomotive, great video!!!!

[@Premier-w3k]

Hello, is there a way I can get a copy of the samples for this test? Thank you so much.

[@TheMechanic2]

Well done video. Like the graphic on valve opening and closing. Do you have it as a downloadable graphic? Would like to show it to some of my helpers.

[@stuartbrown3769]

where can i get that valve overlay tool for my pico ???

[@Linville666]

Great video thank you!

I HOPE TO SEE A CATALIZER TESTING WITH A PICOSCOPE

[@contagiousFX]

Where can I find more information about this? Also would like to download that waveform demo you posted.

VERY NICE.......

[@דודברזילי-ח9מ]

TO DAY IT IS NOT EASY TO CHECK A TWC CATALIZER

So this is telling me that combustion creates no pressure? That's dumb AF. I just missed this on an ASE test question.

[@LeeWs1970]

There is no combustion happening the transducer tool goes in the spark plug hole

[@franciscovera828]

sorry- I commented before I watched video!!!!

Jesus Christ. That was a terrible video. Ran through it way too fast. Hard to understand.
