Proj 7747/101

[Gregory A. Parmer]

Rather than rig up a fake distributor to gen pulses
I am using the real thing on the bench.
Don't let OSHA know, but a $3 fan belt from the
drill press to the bottom o' the distrib shaft
spins it nicely. The drill press has a stepped
pulley which allows me to vary the RPM via gearing.

She ran awhile yesterday at 2800 rpm. A torch flame 
to the O2 sent it immediately to closed loop. The
O2 reading is gonna be a serious hindrance to
bench testing. Interestingly enough, the MAP seemed 
to have as much affect on pulse width as TPS.
Makes sense, figgering that load is kinda opposite
of vacuum ("somewhat inversely proportional" to use the
proper terms).

BTW--The "18mm Sparkplug Non-Fouler" makes a perfect
O2 mounting boss. Thanks to those who pointed it out.
They came 2 to a box and included new gaskets all for
under $4.

questions:
The max RPM (at least reported by the scanner) was 6375. 
Is that a hard limit or just a reporting issue?

What does the "Crossings" value represent? Crossings
from rich to lean as reported by the sensor?

No o'scope available...
