'7730 and TBI?!? (CrossFire/2bbl TBI conversion?)

[chetwagner at qwest.net]

I have been using a 7749 computer with either the Sy/Ty code or 
the 8D code, depending of fuel milage requirements.  The catch to 
using the 749, or even the 730, is the memcal chips.  I have been 
using one from a 4 cyl TBI engine that had the 730 computer.  So 
far, this combination is working great on my 77 FJ40 Landcruiser 
with a TBI off a 4.3.
