some very interesting notes in there...

from the wonderful folks on the internet...

i love the idea of using a LM3914 ( basically an array of voltage comparators) to control the coil power... simple and elegant.

Can you give us a hint where/who this actually came from?

The format sure looks a lot like original Stan Meyer documentation.

Mention of 430FR wire is a Stan source.

Wonder what other secrets "Anony mous" has stashed up their shirtsleeves...

I sure hate being toyed with.

  • An old version of Windows Movie Maker was used, XP.
  • Account registered Wednesday.
  • They had insight on the circuitry before.
  • Russ knew about it shortly after.

Overall, I don't see anything but improvements to the original design.  If you can't get the original to work, you won't get this version to work either.  In fact, this version doesn't even have a PLL lock so you'd have to be spot-on and continue to track frequency as things change.  I'm also not real hip on the coil taps needed or relays for that matter.

Looks to me like this circuit is specifically for the injectors, not the regular WFC.

I see more emphasis on the coil array.

Obviously, more turns == more power.

I think the circuit works the same way.

The most important thing to take from this is the blocking diode is shorting the bemf not used as the original diagrams

I can´t see that ...
which diagram do you refer to?

Good observation chuff.

That being the case, the back EMF must be reflected and sent to the injector as forward EMF, in-phase.

Obviously there is more than one way to skin this cat.
