Nissan
Z
The
JB4
performance
tuner
for
the
new
2023+
Nissan
Z
is
plug
and
play
and
attaches
to
two
easy-to-access
sensors
in
the
engine
bay
and
works
with
your
factory
DME
tuning
to
remap
your
boost,
timing,
and
fueling
for
optimal
performance
and
reduced
turbo
lag.
The
JB4
manipulates
the
ECU
boost
control
signals
allowing
it
to
modify
boost
levels
but
does
not
manipulate
the
ECU
manifold
boost
reference,
allowing
your
ECU
to
properly
map
timing
and
fueling
for
the
higher
boost
levels.
The
end
result
is
something
that
runs
as
smoothly
as
stock
only
with
higher
boost
targets
under
heavy
throttle.
JB4
features
a
64mhz
processor
allowing
sensors
to
be
sampled
1000
times
per
second
using
dedicated
10
bit
digital
to
analog
converters,
ensuring
smooth
and
powerful
performance.
The
JB4
adds
OBDII
CANbus
for
increased
performance
mapping,
a
variety
of
useful
features
such
as
data
logging,
boost
by
gear,
optional
fuel
control
wires
for
AFR
adjustment,
and
on-the-fly
map
changes.
JB4
is
simply
the
most
capable
tuning
system
available
for
the
Nissan
Z.
The
higher
the
octane
the
higher
you
can
safely
raise
the
boost
pressure
over
stock
and
the
larger
the
power
gain.
Wirelessly
connect
the
JB4
to
your
