Rick, Activate the full throttle switch to enrich the system evenly. This
activates the FV to full operation and lowers the pressure on the lower
chamber of the fuel distributor to flow more fuel to the injectors. There
also an operational difference between early fuel distributors w/out Lambda
before 1980 VS distributors after 1980. With out changing the distributor to
a non Lambda one, the switch is a easy mod.
The control pressure can also be lowered to achieve more fuel flow, but this
would be more tricky.

How does one go about tuning the K-Jet ECU for a Lambda less than
1.0?  Greg, you mentioned that the Lambda controller could be
adjusted for both best performance and emmissions (with the flip of a
switch).  I like the idea of the closed-loop system, especially at
the altitude I drive at but would also like to be able to take
advantage of engine performance modifications.  Any advice on the
procedure to get a closed-loop Lambda of 0.89 - 0.86 that could be
set back to 1.0?  There will not be a catalytic converter involved.
Thanks, Rick
