Custom MAF system: help w/ calculations

[Walter Sherwin]

Hi James,

Good luck with your endeavor.  Welcome here.  I won't say much about UofT,
other than to say I hail from Queen's, 'nuff said :)......

Lot's of info about what you're looking for on the three associated sister
lists, namely:  DIY, GMECM, and EFI332.  The archives hold a bunch of info,
and there is an eclectic group of individuals here.  Most lurk, so, you'll
have to ask away with fairly specific questions. Feel free to expand upon
your project, for group input.  Also, drop me a line and I may be able to
interface you with another individual who excels in pondering this kind of
stuff when he's not busy with his day job.

Walt.
