[DML] Re: K-jetronic not connected

["content22207" <brobertson@xxxxxxxxxxxx>]

Welcome to the wonderful world of US government mandated emissions...

That silver box is your Lambda Sond ECU. It's what controls the
frequency valve. Unplugging it has the same effect as unplugging the
valve itself -- lower fuel distributor chambers fail safe to a
constant state of enrichment AND NEVER CHANGE. You can then tune the
engine manually (except for CIS, unless you want to bypass it too).
Thousands of Europeans run their PRV's just this way.

For some reason talking about bypassing Lambda amounts to heresy among
some DeLorean enthusiasts. Yet it was not part of the original PRV
design. F series imports through 1979 ran just fine (better?) without it. 

In theory a DeLo won't pass tail pipe test without Lambda, yet my DeLo
with a Renault block (absolutely no provision for Lambda, equivalent
to E series) came with a current Pennsylvania emissions sticker. Of
course it was tuned funny, which cut into performance dramatically.
