The fuel injection system reads the input airflow just after the air filter
with the "sail" switch. Therefore the amount of boost does not affect the amount
of fuel being provided by the CIS.
However, the ENGINE ( MACxx )computer sees the wrong boost, and reads the
It has no idea how much air is going into the engine, but "guesses" at the
loading by reading the intake manifold pressure, ( remember "vacuum advance" ? )
This is the culprit that provides the incorrect ignition timing.
