Description
We’re
excited
to
introduce
the
world’s
first
complete
Mass
Air
Flow
(MAF)
delete
and
Intake
Air
Temperature
(IAT)
conversion
kit
for
the
Nissan
GT-R
R35.
Aftermarket
engine
control
systems
geared
for
high
boost
application
use
a
speed
density
(SD)
measurement
to
calculate
air
charge
for
combustion.
This
alternate
way
of
measuring
eliminates
the
shortcomings
of
the
OEM
air
flow
meters
which
saturate
their
signal
early
and
are
prone
to
irregular
readings
with
aftermarket
components
installed.
The
OEM
air
flow
meter
device
also
contains
an
embedded
thermistor
for
Intake
Air
Temperature
(IAT)
measurement
used
for
cold
start
assist
and
engine
diagnostics.
In
a
Speed
Density
system,
two
data
points
are
required
to
accurately
gauge
air
density:
The
air
charge
pressure,
and
its
temperature.
A
proper
charge
pressure
can
be
measured
accurately
at
any
of
the
3
sensors
present
on
the
GT-R,
however
the
available
air
temperature
reading
is
built
into
the
MAF
sensor,
which
still
measures
temperature
at
the
cooler
intake
point,
before
turbo
compression,
intercoolers:
Far
from
the
actual
pressure
measurement
point.
So
up
until
now,
the
MAF
sensor
is
still
required
for
its
temperature
reading.
Current
SD
conversion
attempts
compromise
either
the
air
temperature
reading
by
leaving
the
MAF
in
place,
or
relocate
it
to
the
air
charge
intercooler
pipe
near
the
pressure
reading:
Neither
conversion
eliminate
the
use
of
the
MAF,
and
compromise
either
air
flow
or
density
calculation
and
require
custom
made
intercooler
pipes.
After
rigorous
testing,
here
is
the
first
and
most
effective
Speed
Density
conversion
kit:
-
100%
Plug
&
Play
-
Uses
IAT
and
MAP
in
a
single
sensor
package
while
keeping
OEM
look
and
feel
-
Compatible
with
OEM
and
aftermarket
intercooler
pipes
(Aftermarket
pipes
designed
to
accommodate
the
OEM
MAP
sensor
should
be
compatible)
-
Allows
complete
removal
of
MAF
sensor
for
more
efficient
air
flow
-
100%
OEM
readings,
no
sensor
calibration
or
adjustments
required!
-
Complete
transition
looms
with
high
quality
OEM
sealed
connectors
-
Manufactured
with
the
high
quality
SAE
J-5160
wiring
materials
-
Replicated
OEM
wire
colors
-
Fully
reversible:
no
cutting,
no
splicing
&
no
tapping
required!
-
Also
includes
extra
connectors
for
harness
side
MAF
loom
plug
blanking
At
the
heart
of
this
true
Plug
&
Play
SD
conversion
kit
is
a
relocation
of
the
IAT
sensor
from
the
OEM
MAF
assembly
into
the
intercooler
MAP
sensor
package.
This
elegant
approach
at
combining
both
pressure
and
temperature
readings
in
a
single
point
increases
accuracy
and
gives
OEM
look
and
fitment.
Two
kit
versions
were
designed
and
are
available
for
purchase.
SD
KIT
A:
MSRP
$429
Designed
for
the
highly
modified
setup,
this
kit
provides
the
full
MAF
delete
and
pass-through
MAP
loom.
A
pair
of
sealed
terminal
connectors
is
provided
to
blank
the
vehicle
harness
MAF
plugs.
The
engine
side
IAT
signal
is
rerouted
to
the
SD
MAP
sensor
with
a
custom
made
high
quality
loom
that
adapts
between
the
existing
OEM
MAP
sensor
harness
connector
and
SD
MAP
sensor.
SD
KIT
B:
MSRP
$449
Designed
for
a
setup
where
rapid
change
is
required
between
Air
Flow
and
Speed
Density
configurations.
This
kit
adds
to
KIT
A
by
providing
a
MAF
sensor
side
pass
through
loom.
This
additional
MAF
loom
is
normally
sealed
with
blanking
connectors
when
running
in
SD
mode,
but
allows
MAF
sensor
to
be
reused
without
removing
the
kit
and
preserves
the
IAT
sensor
relocation
functionality.
This
kit
is
also
ideal
for
Air
Flow
based
setups
to
gauge
turbocharger
and
intercooler
relative
efficiency,
by
measuring
air
temperature
after
the
intercoolers.
