bit about what MB referred to as CIS and CIS-E injection. They both are
equipped (correct me if I'm wrong) a control module,
CIS ( K Jetronic) is purely mechanical, no ECM used or required. The CIS
is short for Constant Injection System as the injectors spray all the
time rather than being pulsed. CIS-E (aka Lambda ) system used an O2
sensor and a Lambda module ( ie: an ECM.) Other Bosch systems such as
the D Jetronic (Air Flow Controlled or Manifold Pressure Controlled) used
ECMs and electronically pulsed injectors. The MPC system (used on VW
Type 3 ) was pure junk and many owners retrofitted the earlier dual
carbs. AFC was pretty reliable but a backfire could (and would) damage
the air flow sensor and would require its replacement. A backfire in a
CIS system might require the air flow plate to be recentered, but usually
not.
