injectors that have been disconnected,
with “false” injectors, that the
petrol ECU will not distinguish from
the real ones.
As we told before a resistive
type of emulation is already present
in the FLY SF ECU anyway some
kind of petrol ECUs need not only a
resistive load but a resistive-inductive
one
For this reason inside
SEQUENT harness a suitable
Modular LD has been introduced to
supply the inductive load required
by the petrol ECU during the gas
operation when petrol injectors are
disconnected through the FLY SF
ECU. For further information please
refer to § 6.2.17.B.
4.19 HARNESS
As we indicated before, the harness
is one of the main novelties
introduced with the SEQUENT
system. In this paragraph we will
analyse two types with different
characteristics according to the
type of Sequent configuration.
The first (picture 38) is the usual
harness used till now for Sequent
application while the second one
(picture 39) is the new harness for
Sequent Fastness only.
The innovative modular harness
allows installing the simpler vehicles
with the only connection of
three wires (rpm, key contact, TPS:
respectively grey, brown and
white/violet wires), naturally in addition
to the positive and negative
battery.
For more sophisticated vehicles,
that consequently can require more
connections, it is possible to integrate
the harness with further connections
that allow optimising the
vehicle setting up and driving conditions.
Both the main harnesses of the
SEQUENT system have a 56-way
connector, used by some of the
more important European car
manufacturers.
