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
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
