Taking the uScope Class on the Road!
I posted the last uScope class we did here in Charleston, SC and received a lot of great feedback. I have been wanting to do that class more but it took us way to much time to prep and set up for that class to make it mobile.
I've bounced the idea around and I've seen other trainers take the scope class mobile but I'm far too stubborn to do it the traditional way with waveform generators. I'm also not working with a Consulab or Atech budget so I decided to build my own demo board that would allow me to test actual components in a scenario that was as close as possible to live, on car testing. I believe the end result gave us an opportunity to train technicians at a higher level than just using waveform generators and even on car testing. With this demo board we can easily manipulate timing, CMP and CKP sensor gap and even change spark plug gap (even though we don't have combustion pressure).
My hope is that using this board will help technicians to visualize what they are testing. We purchased a used vehicle to make this board so that we had a complete harness with matching wire colors. We ran most of the wires outside of the board which allows us to use actual vehicle wiring diagrams and allows technicians to follow along through our diagnostic procedure as we decide which wires to test and why as well as what waveforms we expect to see.
With this demo board we will be able to demonstrate signals from:
CMP and CKP sensor waveforms, correlation, and amplitude changes due to adjustable gap
Ignition primary voltage and amperage
Injector voltage and amperage
IGF signal from coil to PCM
I am also working on a new signal distribution harness. It is not yet complete but getting close. It will allow us to set up multiple channels beforehand and also the ability to work with just about any room/table configuration.
I'm posting this not just because I wanted to show off my latest creation, but also to promote the next class and future classes.
The next class is taking place on August 3rd in Bluffton, SC at May River High School. See the attached flyer for more info. Contact Sam Johnson @ … to register. We are expecting this course to sell out but if you are interested and can't register for this one we will be doing this class in a few other locations. If you're interested in hosting this class in your area let us know as well!
That demo machine is COOL!
In my head I'm trying to figure out a way to easily add VVT into it too! Love it.
NOPE! Haha this was already a much bigger project than I had anticipated!
Nice job Mike! This brings back old memories of Toyota T-Ten College were we had a complete vehicle on a board it was definitely not mobile but was a great learning experience as it had the entire vehicle wire harness, exterior lighting, and a ignition system... I am sad I don't live closer would love to attend
Thank you! Yea we have some pretty cool Atech stuff at the college. It's pretty dated but still awesome to use for class.
VERY NICE WORK, Mike. I for one, know what kind of time it takes to put something like this together. I would LOVE to be at a Training event that you are doing this class and sitting in when I'm not presenting.
Thank you Jim I really appreciate it! I couldn't have done it without your help! I took your advise and submitted the course for Vision next year so I'm keeping my fingers crossed. Me teaching a scope course with Jim Morton in the audience seems a little backwards but I would certainly value your feedback. Thanks again!
If I'm not presenting at the same time, I WILL BE IN THAT CLASS.
This is fantastic! Changing CMP's airgap would make for some interesting demonstrations if it is a Hall-effect type!
Thank you! These CMP and CKPs are AC sensors and changing the gap changes the amplitude. I have yet to play around and determine at what amplitude the PCM doesn't recognize the signal but I'm looking forward to finding out!
Might want to proof read that second sentence one to, to many. lol On the flyer Hope you get your class to the Philly area.
I second that. We can make Philly easily but SC is too far.
My thoughts exactly, James Allen Smith, on getting Mike up to the Philly area with this class.
I have been doing some classes for AASP-PA. I will see if they have anything they can put together in the Philly area.
I didn't to the flyers but I will pass the info along to Sam, thank you. I'll do some research and see if there is anything I can put together in the Philly area.
Very cool demo board. What is the cost for this class ? Are there any other possible locations ?
