Lamda system mandatory?

["content22207" <brobertson@xxxx>]

Hate to throw sand in the gears, but my PRV runs excellent with
absolutely no Lamda system whatsoever. As soon as I get out of this
sling & wrap will drive the vehicle (fast and smooth) to a fellow w/
digital camera to document (if you look closely at pics in #5939's
photo album you can see what I'll zoom in on -- no frequency valve, no
line to lower chambers, capped O2 sensor bung). True, my fuel
distributor may be different internally (Martin G, could you get
Darren to look into that?). But even if I have no lower chambers,
wouldn't simply removing fuel pressure from lower chambers in a DMC
unit yield the same result? My fuel distributor has a Bosch ID tag BTW
(will quote model number when I get home). Is aluminum.

A properly
set-up and operating PRV won't run right without the lambda system, it
adds a little fuel to make the air-fuel ratio correct. With a dead O2
sensor the Lambda will revert (fallback) to a fixed value. The big
symptom would be a loss of power and terrible acceleration. It is even
worse if the Lambda system is dead completely.

You cannot remove the
lambda and successfully get an accurate air-fuel ratio across the
RPM band without going to another injection setup. Bosch K-Jetronic
has to have the lambda to work.
