The
HKS
VAC
Velocity
Advanced
Computer
-
Type
Z
is
an
electronic
device
designed
to
eliminate
the
vehicle's
factory
speed
limiter.
When
competing
on
the
drag
strip
or
a
circuit
track,
the
factory
speed
limiter
can
hinder
a
vehicle's
performance.
The
VAC
is
a
completely
plug-and-play
application
with
not
need
for
modification
of
wiring/drilling/custom
fabrication,
and
is
a
must
when
wanting
to
go
faster
than
the
factory
settings
will
allow.
FEATURES:
-
VAC
Type
Z
is
a
device
that
cancels
speed
limiter
of
FAIRLADY
Z
for
circuit
driving.
-
CAN
BUS
signal,
which
controls
whole
vehicle
systems,
will
be
used
for
cancellation
of
speed
limiter.
Thus,
speed
limiter
is
canceled
safely
and
surely.
-
Only
4
wires
of
ECU
harness
need
to
be
modified
to
connect
VAC
Harness.
Once
VAC
Harness
is
removed,
it
will
be
stock
control.

As
it
is
an
external
device,
even
if
data
of
stock
ECU
is
reflashed,
functions
of
VAC
Type

can
be
used.

Installation:
-
Modify
4
wires
of
