DFI Fuel maps

[jpearl at qsihome0.qsi.com]

I've been speaking to a new found E-mail buddy cross country about the DFI
system. He's done some nice math with it and I've begun to get a better
understanding as to why my car ran so poorly (smile). One of the things
that's driving us both nuts is having to retype in all of the fuel map into
an Excel spreadsheet in order to do any calculations on it. Has anyone done
any "reverse engineering" with this box? I'd like to find some way to
translate the ASCII text files it can dump for the fuel map into something
akin to what I'd need to do calculations. As I recall they're straight text
but not very friendly.

Also - has anyone written ANY software to work with these boxes or are we
all stuck with the somewhat limited DFI software? I can think of a million
things I'd like to see done in software in order to help calculate fuel
curves. The newest version will generate curves for you but I sure wish
they'd give me some way to feedback the closed loop cycle into a fuel map!

One other thing - awhile back there was talk about developing a wide-band
O2 device ala Horiba at a lower cost. Has anyone been successful at this?
If not, I'm interested in buying or building a decent Air\Fuel meter
(narrow band - I'm not rich yet!). I seem to remember the archives having a
schematic for one but I'd like to know if anyone can recommend  an over the
counter meter. If memory serves a couple were taken apart and found to have
laughable signal filtering. I'd only be using it to calculate VE it would
seem...

P.S. If I could hack the EEC-IV ala Mike's Calibrator I think much of this
would be moot but.... it's not in my hot little hands yet Mike (grin)!
