Are any of your fuel enrichment devices adjustable other than with line
pressure? I'm not sure how accurate it is but the computer than drives the
extra injectors I have has two pots you can adjust. One is the point when
they are activated the other is the curve. I had a part throttle flat spot I
was able to eliminate messing with these while watching the A/F gauge.
In a message dated 00-08-18 16:57:21 EDT, you write:
<< I run the autometer A/F gauge. It's o.k to get you in the 'ball park', but
it doesn't really tell you by what degree you are running rich. Each gauge,
set-up, and O2 sensor gives a slightly different reading. Mine shows 1
yellow (strophic) and 3 green (rich) when I'm under boost, for my situtation
that is around 12.5 to 1.. per Dyno results.
and to answer the other point, 'way rich' will cause CAT failure.....lean
will burn hole in piston, brake rings, etc...and lean means 13 to 1 A/F or
higher under boost conditions.
