Diacom runs and ramblings (longish)

I love the Diacom+. I recorded a 15 minute cruise, all 4902 frames of it
:) However, Excel sucks that it can only plot a measly 4000 data points.
I also got a few shorter runs...

	Well, I maxed out the O2 sensor at 1049 :) Most of my o2's are around
1000, unless I'm off the gas, engine braking. My knock retard is down a
lot. 
		I also learned that the engine adds lots of pulsewidth when its
about to stall... At idle, my IAC is sittin' pretty at 160 the whole
time :p I
guess the big injectors add too much fuel (1.9ms) at idle, and it opens
the IAC to balance the air, but it's too much air. I think I'm
screwed... If my pulsewidths are small, how will I ever idle, since the
DFI can't shorten the physical time to open/close the injector. Is 1.6ms
the shortest recommended time for 30# SVO injectors? 
	I don't notice a huge change in O2's from almost WOT to WOT, but there
is an incredibly
large bog.... Maybe I'll set up a throttle stop/block under gas pedal
for the autox sunday... These are the ramblings from my latest diacom
runs as I've analyzed them. I've got them all saved as excel graphs if
anyone wants to take a look...
