Frequency Math

[@alexanderorozco661]

You are unique. Thank you

[@thisisausername1265]

For idle speeds only, putting a lower limit on the hz (say 550-300hz) will remove some of the spikes dropping downward from the missing trigger wheel teeth. Makes is visually more pleasant IMO.

[@CartersDiagnostics]

I'll have to try that. Thanks

Almost 1k Mr Carter 🎉. We getting there

[@CartersDiagnostics]

Heck yeah, The channel is getting some traction. Thanks for the support!

@@CartersDiagnostics for real. Keep it coming

[@Lambros_Stefaneas]

very nice explanation my friend 👏.we (or at least i) want more frequency/math channel explanation.thanks for your effort to teach us.

[@CartersDiagnostics]

Thank you, glad you commented. I will try to incorporate more explanations on frequency math in upcoming videos.

[@ELEISONCARABALLO]

Very good video. I am curious about the snap throttle technique for diesel engines. Would you make videos about diesel engines drive-ability problems. Another thing: Why do you prefer Pico 6? Thanks again.

[@CartersDiagnostics]

If something cool comes in with our diesel engine i will try to record it. Pico 6 is what I started with and I'm just slow to change.

Have you ever locked a NISSAN crank signal with pulse WIDTH trigger to see timing chain slop thanks MIKE

[@CartersDiagnostics]

Yes 👍. Here is a small video on my Instagram where I use it. 2020 Nissan Altima 2.5. Using a scan tool and Pico to explore the E-Ivt system. Also utilizing an advanced trigger within pico. #oscilloscopeawareness #automotivediagnostics #testdontguess #nissan #mastertech #alwaystraining #picoscope instagram.com/tv/CTAdfT4FQNo/?igshid=MDJmNzVkMjY=

Sir,you have amazing skills in using picoscope 👍 👌 it's a great explanation. Question-how do we know the onecycle using rising Edge to rising Edge as you said its 433 hź? Thanks.

[@CartersDiagnostics]

At around the 3:34 mark, I show the 433hz in the lower right corner of the screen. That's how I came up with that number. Thanks for the support!!

[@markferraro5250]

Thanks can you make a video on an RPM CHANNEL. thanjs CARTER

[@CartersDiagnostics]

Try the link in the description box. It goes to my Instagram page. Its about a 10 minute post that explains the RPM math channel.

How do we do this on a generic snap on scope with out math channels? I have a 2009 Saturn cue that counts misfire on cylinder 6 but sitting in the seat it doesn’t Even feel like it’s missing. Trying to see if it’s a bad pcm or if it’s actually missing

[@CartersDiagnostics]

Im not 100% sure, but I dont think you can on a S.O scope You coul howevver use a pulse sensor in the tailpipe to verify the mis-fire

[@kyletuttle9064]

Great information thanks

Thank you. Awesome.

Buongiorno, complimenti per il video. Volevo chiederle se è possibile visualizzare un segnale del sensore giri motore induttivo a 60-2 denti (forma di onda sinusoidale) come lei a fatto con il segnale del sensore massa aria creando il canale matematico. In pratica poter vedere quando il motore accelera ad esempio da 800 a 2000 rpm su un grafico con una sola linea come quello di colore nero del sensore massa aria, grazie

[@CartersDiagnostics]

Yes it should work on analog signals as well. A filter may have to be applied to the signal to make it work.

[@andreai9165]

@@CartersDiagnostics ha una formula da consigliarmi? O il settaggio da inserire?

[@CartersDiagnostics]

@@andreai9165 Do it the same way as I did at 2:22, just assign the channel your wave is on. I just tried it on an analog signal, it works great!

[@andreai9165]

@@CartersDiagnostics Ha perfettamente ragione, complimenti, ho testato la funzione su molti segnali acquisiti e in varie velocità motore: al minimo 800 rpm eaccellerando fino a 4000 rpm e, naturalmente se modifico accuratamente il range del canale matematico del valore minimo e massimo, si riesce anche ad analizzare i giri tra 3000 e 4000 rpm. La forma d'onda mostra sempre le accelerate e rallentamenti come nel suo video, mi chiedo se sia possibile invece creare un grafico lineare dove analizzare solo la velocità giri motore come se fosse un contagiri o come vi vedono nelle autodiagnosi, così che magari durante un test su strada si possa osservare un rallentamento del motore o una pediata di giri improvvisa, e poi in seguito analizzare nel dettaglio come ha fatto lei nel suo video

[@juergenscholl2843]

Thank you Mike. Your comments on stressing the secondary ignition when snap throttling sounds like best Mac Vandenbrink simply, great 👍

[@CartersDiagnostics]

Mac was a wizard on secondary ignition. I have some of his study material. Thanks for commenting.

[@mandytuning]

Something is not right here, from peak to peak there is around 128teeth, that's 1280 degrees in a 36-2!!

[@CartersDiagnostics]

Hmm. Not sure I'm following.

[@mandytuning]

@@CartersDiagnostics supposed to be 720 degree from compression peak to peak. In a 36-2 thats 72 teeth.

[@CartersDiagnostics]

Exactly. I just checked the file from that video 68 teeth with 4 missing from compression peak to peak. Thanks for making me re think this. I need to be kept on my toes 😄😄
