I have installed the air fuel/gauge from JC Whitney to monitor the
operation of the Howell TBI.
So far the meter has shown how hard the computer in the Howell TBI system
is working. With a
cold engine at 2000 rpm, with the computer locked in closed loop operation,
the readings are going
all the way from the bottom reds up through the top two yellows. The
lights go up and down very
fast showing the computer is working very hard to keep the engine at rpm.
The engine sounds
smooth but if you listen while watching the meter, it is possible to hear
the variation in engine
sounds that go with the meter readings. It is fascinating to watch the
computer work..
Now off to some road tests to see if the computer has enough control to
keep the engine "in the
green" in all road conditions.
You can read the details on my Howell page.
