It is alot of work, but well worth the time.

Agreed wholeheartedly!  However, the price is somewhat of a deterrant, 
and even a sharp engineer will have to rework the design a few times, 
and calibration is an ongoing effort, so it ends up being a perpetual 
project.

Mine runs very well though, and all of the drivability issues that I had 
with the CIS are gone now.   Reliability is 100% better too.   Probably 
the biggest advantage though is that now if there is a fuel-related 
problem, I have the tools to diagnose the problem _exactly_ instead of using 
the shotgun approach that I had to use with the CIS.

Oh yeah, it also makes _alot_ more power than it did with the CIS  :-)
