First look sensor Exhaust pressure pulse analysis in depth and misfire diagnosis on Honda Fit.

[@jessemackenzie6516]

Your videos are my #1 go to when I am trying to show a friend how useful scopes are. You have a great way of highlighting the power of a scope that anyone can understand.

[@ravifixall]

My pleasure.

[@eranda5268]

Excellent explanation & use of new technology 💪💪

[@Grunter123]

Brilliant Ravi, you have helped me understand the pulse overlay much better.

[@ravifixall]

Thank you Grunter

[@ernestdamo677]

Thanks for the knowledge you have provided to us

[@djmobileautoservices]

Excellent presentation bro. It's crazy, I made the call on where the misfire was before you put up the overlay chart. Scoping is an addiction. Lol.

[@ravifixall]

You are right my friend. Scoping is an addiction, also it made mechanic life easy and accurate.

[@Backalleydiagnostics]

Great vid Ravi. I am new to a lot of this, and I like the theory part, along with seeing affordable equipment that I have in use. Also, you deserve an award for the best presentation with a brake clean nozzle!

[@chrisingram7277]

😂😂It took me a moment to pick up on the brake clean nozzle comment

[@ravifixall]

Thank you my friend.

​Hi Ravi please, make a video on your findings and also teach us the theory for how to analyze inclinder pressure pulse for valve diagnosis... Your videos are great source of learning and helping a lot, so don't take too much time for coming out with a new video 😊 ❤❤❤

[@ravifixall]

Thank you

[@geoepi321975]

High Ravi, your videos are very interesting, i wonder if you can correlate intake, exhaust and pressure waveforms as a hole to make a decision about the condition of an engine..

[@ravifixall]

Will try

[@NEMOJA]

Ravi, would the waveforms be the same with the pulse sensor in the dipstick? I'm learning so much from these hscope videos! Thank you 👍🏼

[@ravifixall]

Pressure pulse waveforms are almost same.

[@mandytuning]

Its on mode 6 generic obd2.

[@saibabupodala6297]

Make one video intake puls

[@alexandrumardare828]

But this engine is not running right now, is it? If you have a running engine than you would see pulses upwards?

[@thesmartguy3523]

Nice. But what was the actual cause ?

[@ravifixall]

It was a mechanical issue that poorly opened intake valve caused to misfire. It reveals by an intake pressure pulse analysis.

[@AutoDiagnosticsPK]

​@@ravifixallplease, make a video on your diagnosis or at least teach us the theory for how to analyze inclinder pressure pulse for valve diagnosis...

[@alexandrumardare828]

I don’t really get why there is a vacuum in the cylinder if the cylinder is combusting

[@ravifixall]

I think you get confused with this explanation. Anyway those 2 waveforms I used in this video are not on a same car. Pressure pulse wave form is taken on an other car and in cylinder pressure wave for is from another car, I just try to explain pressure change in the exhaust pipe .

[@alexandrumardare828]

@@ravifixall Is that pulse waveform from a Running engine?
