RATS!!! I bloody hate it when this happens. CRAP.  I KNEW there was
someone else that had posted on this Moto pressure sensor stuff, and it
WAS SteveGork that first mentioned using these devices in his flow
bench, to me. I looked back in my archived posts, and in the time I took
to look, I found Jack's followup, but not Steve's initial post, so mea
culpa. YEAH, yeah, I know we're not running the no-bell prize committee
here, nor the Academy frigging Awards, but it's a pisser when someone
contributes some essential lead, and ends up not getting the credit he's
due.

So thanks Steve for the lead and for graciously not getting pissed at me
for not giving you kudos where it was due. I don't mean to make a big
deal outta this, but this whole bloody group clicks and runs on the key
inputs of this kinda stuff, and so I ALWAYS wanna thank those that put
in the essential plug-ins that make the whole thang run. That lead for
them Moto devices is KEY to me building the FB of me dreams. Nough said.

BUTTTT just to give ya an another way COOL example of how this dynamic
works, consider the following. I post sumpin about ION not seeming to
involve alot of special sauce in order to work, and Joe Zivnak posts a
comment on the original Saab patent (hey Joe, what you did dude!). OK,
so I go over to the IBM patent page:
	http://www.patents.ibm.com
look up the patent Joe mentioned ( 4,862,093 ), and *danged* if it's not
almost the exact same schematic that I've pulled from that '90 Saab DI
module I got from my Saab parts dept. buddy, some of which I've been
scratching my head for days, wondering "now why did they do THAT?" So
now I have a running commentary of how the circuit I'm looking at works,
POOF! Hah! WHERE else, I ask you, could this sorta thing take place and
gell, except for groups like ours!!

Not to sound like I'm gushing over the obvious, lemme just drop another
lil gem I got outta that patent, thanks to Joe, that REALLY sweetens the
pot: (page 6, the last page of the patent text)
	"Although the invention has been exemplified with reference to a
capacitive ignition system, it will be understood that the invention can
also be applied with an inductive ignition system."

Hee hee. Here, where the Saab patent attorneys try to cover their bases,
should a counter claim be made that THEIR patent & technique only was
possible/feasible and therefore only applies to CDI, they hand us a
royal golden EGG, by confirming that there's nuthin particularly crucial
about using CDI with this system. Now, lest you think this is a mere
detail of minutia, consider the fact that CDI is notorious for producing
MUCH faster sparks than inductive IGN, and so I had always harbored some
fear in the back of my mind that we might not be able to use this
technique on our stock IGN systems, simply because by the time the
inductive spark ionization finished, there'd be nothing left to work
with, vis-a-vis ionization detection. This one lil sentence in the
patent disclosure says "not to worry", we WILL be able to apply this
technique to our normal inductive IGN system fired plugs.

So, just to illustrate how vitally important the fractional wit system
is to our endeavors, I offer these two prima facia examples. Hey, I can
now even post a schematic with values on it, from the Saab module I
have, since the patent discloses and protects from commercial
exploitation, that very circuit!! Howja like THEM apples, maties? Make
use of it for your own "research" purposes, and you're fine; try and
cash in on it, and you're in a world of hurt! Ain't it grand! I LOVE it!

Wahhhhoooo! ION lives! And she's prettier than ever. Whew, wadda rush.
