always nice to see you here, Matt:)

Nicely done. Good for chasing head gasket problems.

[@theGADGETSplaylist]

yep, great tools we have at our disposal... thx for comment!

[@mikep95133]

I don't understand the timing overlay, yet. But I totally get the sync signal. That's everything on any scope. Great going Denis !!

[@theGADGETSplaylist]

Hi Mike! Getting the gist of timing overlay on a 4 cyl engine is a good place to start. It'll come to you:)

[@mikep95133]

@@theGADGETSplaylist Thanks Denis !

[@Jpilgrim30]

You’ll get it just keep pulling it up and using it any time you pull a pressure waveform and it’ll start becoming more clear especially once you see a few known bad issues that you can correlate it to. I remember the first time I used one it looked very busy and noisy but after a little while it became more and more intuitive.

[@davesage9190]

Pretty cool demo. I'm going to have to give that a try. Thanks Denis.

[@theGADGETSplaylist]

yep, all done with our trusty HS402 Dave!

[@chriscadman5715]

Always an excellent video. You're a very creative guy. Thanx! Quick question: Do you have any videos on setting up and using the MT Pro software? Thanx...

[@theGADGETSplaylist]

the little I can tell you about MT PRO software is that an english version is available on the ROTKEE site...so the user interface will be in english...but there is no english manual available... thank you for the kind words, Chris:)

[@TheGibby3340]

Nice...I'll have to poke around that feature. Need to get myself some pulse sensing gear. Cheers Denis 👍

Nice one Denis. I didn't know hscope had the piston overlay! I'll have to get working on it!

[@theGADGETSplaylist]

I think the only overlay missing right now is valve overlap. I'll spend time with Martin when he's free and maybe get that one done... Take care, Rome

[@romanosautomotive]

@@theGADGETSplaylist Excellent. Look forward to it!

I haven't had the chance to use the Hscope software but it looks like you all are really turning it into a great product!

[@theGADGETSplaylist]

Portable and powerful, PJ I got involved with HScope release (69). It's now (190) Will help Martin add valve overlap overlay in near future... Now that you bought a hot air reflow station, you should build a HS402 PRO:)

[@billrimmer5596]

the GADGETS playlist Over the years u have brought our level of thinking much higher. A vibration is not just an annoyance, it has a frequency which we can observe by means of an oscilloscope. The intake manifold is filled with pulses that resonate and can have an effect on other cylinders as their valves open, or fail to do so. Many of these effects can b observed with the tools u help us to understand. Translating pulses, pressures, and vibrations into frequency and magnitude as observed on the scope is the object of many of your lessons. So a dead miss on cylinder 3, a failed intake or exhaust valve is going to upset the relatively smooth flow of air thru the engine. And relating that to the firing order by syncing a cylinder is an invaluable diagnostic aid. Getting that info on a second channel that in real time is relating to the first channel is the key. Being able to explain to others helps us to ground the understanding in our own mind. Fun and games in the OK corral

[@theGADGETSplaylist]

@@billrimmer5596 the exhaust manifold resonances (tuning) would be interesting to explore also. I toy with a few ideas now and then on how to explore it. It's just a step step too far...for now:)

muchas gracias amigo:)

[@chuckreed2677]

Thank you for teaching. I am confused because when I saw this I would have thought that this engine had an issue because of the peak amplitude differences of the vacuum draws. To me cylinder 7 peak is almost double that of cylinder 3 and the positive swing after cylinder 7 intake closes appears larger than the others. Admittedly I'm struggling a bit to decode this since the overlay always shows 2 cylinders in each cycle. I realize this may be more than you can explain in a comment. Thanks again.

[@theGADGETSplaylist]

it is more than can be explained in YT comment section Chuck... it's why I invite those with a deep enough interest to join us on HScope Telegram Group, a platform that does better lend itself to discussing complicated topics... follow this link if interested Chuck: t.me/hscope Denis

[@rs1971camaro]

The loop around the ignition coil would be the ticket paired with the HS-101 BLT for test drives if you don't want to back probe.

[@theGADGETSplaylist]

I suppose it would, Jim. The idea was just to get a sync without consideration to waveform quality. But put a chunk of copper near these COP and we can't help but get a decent secondary.

[@osvandremolinari]

Great, thank you

[@theGADGETSplaylist]

welcome:)

[@osvandremolinari]

Hello Denis I saw in a place that it is not necessary to use a motor vacuum transducer equipped with a map sensor, the only thing to do is change the oscilloscope coupling to AC and capture the MAP signal directly, use the sensor negative to minimize noise. Have you tested this type of reading? I will test this weekend. greetings Osvandré

[@theGADGETSplaylist]

I am not familiar with this Osvandre, don't think I can not be of much help...

[@osvandremolinari]

@@theGADGETSplaylist Just an idea that came up, I don’t need help, I’m just commenting that in some cases you can dispense with the use of a vacuum transducer.

[@theGADGETSplaylist]

@@osvandremolinari piezo based pulse transducers can not be replaced by MAP sensors, if I understand your project/plan properly.

[@yipchitaywonga]

Once again awesome video!! I've been meaning to ask, which tablet are you using? Thanks

[@theGADGETSplaylist]

In video, it's a 10in LENOVO TAB4 ... great tablet, unfortunately discontinued. The new LENOVO have MediaTek CPU in them. Might be OK but I'm reluctant to recommend anything with that brand processor. Thanks for comment, Yipchi:)

[@yipchitaywonga]

@@theGADGETSplaylist Thanks, will keep an eye out for a used one

[@9josealfonso263]

Hello, first want to thank you for your channel, looking your lessons was amazing for me to gain knowledge ,recently I've purchased a VATO oscilloscope 4 channel, but for my suprais, the record length is not near hscope possibility, how will be possible to include a license for this one ,thanks in advance.

[@theGADGETSplaylist]

thank you for your kind comment Jose Martin Loren is the actual developer of HScope. There's a lot of work involved in adding support to a model. VATO is expensive and is still only 8bit vertical resolution. Martin already supports Hantek 6074 which also has 4 channels and only 8bit resolution but only costs 1/4 the price.

[@9josealfonso263]

Yes , I had a 6074 and gave it to my brother, and purchased a VATO for the battery that is included and wasn't too expensive, 220 actually, work great, don't crash like 6074 sometimes using the 4 channels for long periods. Also, I have HS502 ,amazing scope, but many times, I needed a 4 channel. Thanks for the reply .Thanks for your support.

[@9josealfonso263]

I know that's a lot of work for adding an oscilloscope, I have no idea about it, but that is why I had to ask ,due to big tasks that I don't know, nothing about it. Thanks.

[@theGADGETSplaylist]

@@9josealfonso263 people do ask Martin directly in our Telegram HScope LOUNGE to add a specific scope model feel free to try that ... and am sure you'll find many interesting oscilloscope related topics (and other things) discussed there

[@donho9670]

Denis, you replied to a below post regarding what tablet you use. Believe you said yours is a now discontinued 10in LENOVO TAB4. If you were to upgrade or had to replace yours could you recommend a good(budget)tablet for HScope use? Thanks.

[@theGADGETSplaylist]

I am still partial to the LENOVO products, purchased directly through their site and especially on sale (sales are frequent but for short durations) The current model to look for is the M10. I had been hesitant to recommend it due to their adoption of MediaTek CPU but members on our TELEGRAM group assure us that this is not an issue with these models and are quite pleased with using them for HScope. Good luck Don:)
