J&S Universal unit showing knock retard waveform

This video would benefit from an introduction explaining what's going on for a viewer who has no previous knowledge of what you're doing. You can assume standard background knowledge, e.g., what an ECU is, what an oscilloscope is, how electricity works, etc. But the specifics of what's on your bench were hard to me to grasp.

Fair enough. I'm a small manufacturer, and make knock controllers for distributor and coil on plug ignition, with versions for dumb coils and for smart coils. I have a few videos on my channel showing operation. Originally this was going to be a retest of a customer's J&S SafeGuard. I don't use a script and since "it was a retest", didn't feel the need to explain the purpose of the system. The SafeGuard is an individual cylinder knock controller. He has the Universal version for distributor ignition.

​@@jselectronics8215maybe change the video titles to what the content means instead of the date?

[@jselectronics8215]

@@koushiroizumi0 Yeah, sorry about that. KZbin puts the date in as a default when you forget to add a title.

I don't really know what's going on but this looks like a pretty neat little device!

The J&S SafeGuard is an ignition timing controller that listens for knock then retards only the knocking cylinders.
