Featuring the HScope Cylinder Timing Overlay while putting to work the HS402 PRO oscilloscope, Pulse Transducer and COP Sync Probe all built on this channel. ROTKEE site: rotkee.com/en/...
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.
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:)
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...
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:)
@@theGADGETSplaylist I just watched that one also, actually referenced it on a Pico FB group post. You have some excellent video’s. Perfect DIY channel thanks for sharing all this stuff!
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.
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.
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
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
@@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:)
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 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.
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:)
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.
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:)
4 channel support only for HANTEK 1008 (very limited oscilloscope) at the moment... You might be interested in our TELEGRAM HScope Group, Bannie t.me/hscope Denis
@@ozriblit I know recently 4 channel support was extended for 6074. I left a message for Martin to clarify if that includes 6074BE as all those suffix get confusing. I'll get back to you when I get Martin's reply...
@@ozriblit it is only available on BETA... if you scroll down on HScope Google Play Store page you will see option to join BETA ... double edged sword as you get latest development but may have bugs...many of us are on the BETA version... HScope TELEGRAM group is a great resource for those interested: t.me/hscope Denis
