I am amazed coming across this channel. I am wondering why so far only 7k subscribers. I am going to let many more aware of here.

[@daveunbranded]

You diagnosed something that would have taken a shop tons of money and parts in 5 mins. I am so damn impressed by you Bernie

[@tech1302]

I have seen one 4.6 dohc in a Mercury Marauder have a worn out key slot on the wheel. Definitely not a normal issue but apparently it does happen. What I do know is most shops don't even know what a lab scope is let alone how to use it for diagnosis. GREAT VIDEO thanks

[@JOHNPHUFNAGEL]

Bernie you are a F ing genius and your tools are awesome! I wish I could give you 50 thumbs up!

[@rusty1187]

The more i see this software in action, the more impressed i am! I originally thought the price tag a bit high, but after watching a few of these diagnostic procedures, I cant wait to purchase this! i can easily replace at least 4 diagnostic tools with this!

[@8SecSleeper]

How's it working out for you

[@rusty1187]

@@8SecSleeper have not bought one yet, the price tag is a bit steep: $1500.00 last i checked. but it does have some features that none of my scan tools can do.

[@DIYDaveOK]

As I've heard other sage techs preach, "Never trust your scan tool data!" LOL really enjoyed the diagnosis. Thanks so much!

[@michaelbuela8403]

Good Engineer, Good Quality Tools and Technology.

[@jwhiz3219]

Bernie, You are absolutely right. Using quality equipment along with a method of best practice to capture and analyze the data is key to finding problems. I see the first 2 pieces of data you collected was the CRANK POS SIGNAL and the #1 coil signal. Then you retested with a pressure transducer, getting a reliable mechanical reference by way of cylinder compression and cycles. It still showed the ripple of the crank signal. Once you proved that the fault was a loose crank reluctor wheel and then repaired it, I appreciated your follow up to show a good crank signal with the tight reluctor wheel. THANKS SO MUCH FOR YOUR GREAT DEMONSTRATIONS!

[@jcmobilediagnostics8611]

Nice Bernie! Pico can graph the frequency of the crank but the E-scope does it flawlessly!

[@joshr8176]

This is a great diagnosis, please keep pointing out the anomalies in the wave forms as that helps all of us, including some of us using less powerful scopes and tools. The wave forms with information, I feel is the key factors, not always the specific tool. ( I understand this is to help sell a tools platform.)

[@exmotorsports]

Absolutely amazing stuff Bernie. Thank You so much for sharing your wisdom with us.

[@baxrok2.]

Impressive diagnosis with an impressive diagnostic tool. Thanks!

[@SimplyDiagnostics]

Awesome case study Bernie, I need to use this function more. As a long time Pico user the learning curve on your scope has been steep. The truth is, the comfier I get with the escope, it's fast becoming the first one I pick up for fast diagnosis. ⭐⭐⭐⭐⭐

[@EliTheOBDTech]

[@paulberumen9258]

Great diagnosis, thank you for sharing your knowledge.

[@YuckFou0x0FFFF]

I always love your videos because everyone thinks a Tech's job is so simple that instead of paying for a diagnostic, you can simply go to an Auto Parts and they will tell you exactly what you need free! Wrong!!! With that logic, if I have a burning sensation in my loins I should just go to the Pharmacy so they can tell me what I have and prescribe the right medicine.

Amazing troubleshooting. All that because some rookie didn’t install the harmonic balancer properly.

[@eliteautomotivediagnostics4424]

Wow! Awesome work Bernie.

[@EXOVCDS]

How is it that your scan tool can get live sensor data (coolant temperature, battery volts, vacuum etc) at the left of the screen while going to get mode 6 data? Every scan tool that I have ever used can only do one task at a time. Live data, mode 6, monitors etc. while eScan seems to be getting info from all different options at the same time, or at least allows you to (what it looks like).

[@ZIGZAGPRODUCER]

A true Mechanic!

[@edwinbrewer1789]

At 16:18 I believe the cursor was placed a touch further to the right. I believe that added a peak on your crank signal. To be clear I don't think it changed your result. Thank you Bernie for sharing these videos. I am learning a bunch!

[@Discretesignals]

I wonder what the power balance graph would have shown? If you see drop outs in the graph, but don't feel it missing that could be an indication of crank sensor signaling issues? Then it would be time to break out the scope and pressure transducer?

[@shakeelsss]

I am always impressed

[@jameswasher3938]

[@spiraldarian]

[@madmike214]

Absolutely amazing! Can this be done with other scopes? I want an escope so bad! Planning on an escan elite first though

[@2nickles647]

Yes. Buy a Pico scope. The tool that Bernie has is built into his tool.

[@Carlitosway211]

I like how you burn the shop without outright burning the shop. "What we need to do is actually diagnosis it"... LOL But man, some of these shops. Sending em out without verifying the repair.

[@chadchiasson7768]

Great catch, but lm puzzled why the tone ring is moving ( even with the loosened harmonic pulley bolt)? My 97 f150 4.6 Windsor has a tone ring keyed with the crankshaft. Is this one set up differently? Just did a timing job (PM) and had to reuse my CS bolt. I purchased the wrong one ( I know torque to yield bolt) but reuse it. Going to change out but expect the tone ring position to still be good, or am I mistaken. Thanks

[@swordofthelord7104]

Pico need to up their game!

[@scientist100]

Isn't the processing something similar to the negative channel in the pico scope feature? I'm trying to figure out what that process data does, I think that is achievable with the pico processing part but I don't know for sure.

Can this testing be done on any scope? Or can it be done on a snsp on vantage? And do we need a cylinder pressure sensor? Not that I don't want a eSCOPE its that I got bit by the snsp on bug and was able to buy on credit/ payments. Thank you Berney Thompson.. And do you want a brand new Vantage in trade for a eSCOPE?

[@carlodonnell146]

Thanks Bernie !!!!!!!!!

[@Discretesignals]

Wonder if you watched the signal live at say a smaller time base and set a trigger on a compression peak. Then watch the crank signal shift back and forth against the trigger point.

[@memphis_sean8169]

This guy is intense 😮

[@jharrison6557]

Amazing. The average car owner has no clue how incredibly complex diagnosing modern vehicles can be and the associated costs for diagnostic equipment necessary to do that. On a side note, what were the pink/purple lines with the cylinder numbers above them you were using to compare ignition and transducer signals against?

[@lupopina3616]

Couldn’t the same test be done by comparing crank and camshaft relationship? I mean trying to detect the movement on the reluctor wheel for crankshaft.

[@Discretesignals]

That would be really difficult to see if you were referencing it off of the cam signal because of chain lash and VVT phaser action. You really need a point of reference that is consistent such as cylinder pressure.

[@johnbriscoejr9738]

Bernie, could you have use an oscilloscope and discovered the same pattern as the firing order pattern?

Where are you located? I have a 2008 E250.

[@1fnjoreinhofer940]

The scope diagnostics and theory are awesome , but typically if the damper isn't fully seated there be other clues where to start looking , like customer mentioned it started running lousy ever since the front crankshaft seal replaced, and serpentine belt noisey afterwards. Luckily loose damper didn't trash the crankshaft, and end up needing the motor replaced. I think I would have pulled the crank sensor and looked inside with snake camera and tried a little pushpull on the trigger wheel with a long blade screw driver or pick, and try tightening the damper bolt before pulling the entire front of motor off if it didn't have chain noise or cam crank correlation besides.

[@johnferreira9223]

Huh???? ....w0w!!!! I just got a '96 E250 for free. Now I'm scared to work on it. Dammmm....... I think he is way over my head. It's a van ...... Not a spaceship! Lol. I haven't use an oscilloscope since when I was an 2001 electrical Apprentice.

[@kevinbarry4325]

Find a local car crusher, at least you'll get a couple hundred for the junk..

[@STBRetired1]

I can remember not so long ago when you didn't need a PhD and tens of thousands of dollar in test equipment to fix your car or truck. It's sad that industry had to over complicate car technology. Seems like there would be simpler and cheaper ways to reduce emissions and that would make cars simpler and cheaper to produce and maintain.

[@kevinbarry4325]

People ask me why I drive old trucks,vans and car I CAN PUT PARTS ON..the new cars today are a confusing mess..unless you have endless amt of money to waste..

[@rschreck876]

So the shop replaced a bunch of parts (charging the customer a ton of money) BEFORE actually diagnosing the problem? Hopefully this shop isn’t anywhere near me.
