Dual
Intakes
just
got
a
little
easier
on
the
Z32.
The
Version
2
Selin
Dual
MAF
Translator,
like
its
predecessor,
offers
accurate
and
easy
conversion
to
a
proper
dual
intake
system.
With
true
dual
MAF
air
intake
metering
and
plug-n-play
installation
this
product
allows
you
to
upgrade
to
a
dual
intake
without
the
need
for
an
ECU
re-flash.
You
could
install
one
in
the
morning
and
take
it
for
a
cruise
that
afternoon.
Even
better,
if
you
have
the
classic
dummy
MAF
setup
and
have
been
considering
upgrading
to
a
true
dual
MAF,
the
product
is
DIP
switch
selectable
to
work
properly
with
dual
pop
tuned
ECUs.
Combined
with
the
elbow
kit,
power
gains
as
much
as
30hp/30ft-lbs
have
been
realized
on
lightly
modified
twin
turbos.
The
new
V2
design
includes
high
quality
OEM
male
and
female
connectors
with
the
more
modern
quick
release
latch.
No
need
to
run
wires,
cut,
splice
or
solder…
just
snap
it
in
place
and
you’re
done!
The
circuit
enclosure
is
molded
from
automotive
grade
PA66-GF10
for
strength
and
longevity
in
the
harsh
automotive
environment
Inside
the
case,
the
circuit
board
is
rubber
encapsulated
to
protect
against
water
and
moisture
as
well
as
combat
vibration.
Combined
with
the
individual
wire
seals
on
the
connectors
the
unit
can
be
considered
waterproof.
The
mounting
bracket
tucks
the
unit
away
conveniently
next
to
the
filters
with
factory
fit
and
finish.
At
redline
the
Nissan
300ZX
fires
at
350
cylinders
per
second.
The
translator’s
high
speed
digital
signal
processor
updates
the
output
signal
over
1000
times
per
second
to
ensure
the
most
accurate
and
up
to
date
information
is
available
to
the
ECU
at
all
times.
In
addition,
each
unit
is
individually
serialized,
tested,
and
tuned
during
manufacture
to
ensure
1%
or
better
accuracy
across
the
entire
operating
range.
Flow
bench
testing
in
the
“ADD”
configuration
shows
incredibly
accurate
metering
to
over
800CFM!
The
“AVERAGE”
setting
in
combination
with
a
classic
dual
pop
chip
doubles
that
figure
for
truly
wild
setups.
In
a
traditional
single
intake
setup,
you
hit
the
single
MAF's
limit
near
500hp.
The
Selin
Translator
can
be
run
in
ADD
mode
to
support
two
MAFs
without
reprogramming
your
ECU,
but
if
you
are
looking
to
make
over
500hp,
you
can
pair
the
Selin
Translator
in
AVG
mode
with
an
ECU
upgrade
tuned
for
dual
POP.
This
gives
you
the
best
of
both
worlds--accuracy
of
dual
MAF
with
the
HP
ceiling
of
a
dual
POP
ECU!
Additionally,
if
your
ECU
is
already
tuned
for
dual
POP,
it
will
already
be
compatible
with
the
Selin
Translator
in
AVG
mode,
and
you'll
get
better
accuracy
than
with
your
aging
single-MAF
setup!
Sub-harnesses

A
New
Wiring
Approach
The
2nd
gen
translator
continues
to
offer
digital
precision,
true
dual
air
intake
metering
and
easy
plug
and
play
installation...
a
combination
that
has
proven
to
be
a
popular
way
to
enable
the
power
potential
of
dual
intake
paths
with
any
intake
hardware
choice.
The
new
unit
departs
from
thru-wall
case
wiring,
instead
opting
for
an
ECU
style
23
pin
harness
connection
point.
This
serves
a
number
of
purposes.
First,
the
subharness
approach
produces
wiring
that
is
far
more
robust
with
enhanced
fit
and
finish.
Second,
it
allows
the
owner
to
purchase
a
standard
length
unit
and
later
upgrade
to
an
extended
subharness
or
to
any
future
subharness
options.
Laid
out
like
a
small
ECU,
the
translator
was
carefully
designed
using
industry
practices.
The
entire
assembly
below
shows
the
removable
standard
subharness
and
the
new
reversible
bracket.
The
LED
Status
Light
A
Bi-color
LED
light
was
added
to
provide
valuable
information
about
the
health
of
your
sensors,
wiring,
and
translator
unit.
In
normal
operating
conditions
a
green
light
will
display
for
exactly
3
seconds
after
power
on.
This
indicates
that
two
sensors
are
present,
providing
voltage
within
their
operating
range,
and
the
wiring
to
the
control
unit
is
fault
free.
By
default,
both
the
green
and
the
red
light
indicate
that
the
translator
itself
is
functioning
properly.
Should
it
fail
to
properly
operate,
no
lights
will
illuminate.
Both
red
fault
codes
(1&2)
then
only
apply
to
sensors
and
harnesses.
Once
triggered,
the
red
codes
will
display
until
the
unit
is
restarted.
The
lights
are
informational
only
and
do
not
alter
the
calculations
within
the
unit.
The
graphic
below
illustrates
the
lighting
patterns
for
different
conditions.
Enhanced
Waterproofness
On
the
original
translator,
connector
boots
were
chosen
per
the
Bosch
standards
that
spanned
through
the
early
80's
to
the
early
90's.
Individual
wire
seals
were
not
attempted
then
because
of
shorter
warranties
combined
with
the
costs
of
the
precision
needed
to
form
finer
assemblies.
Later
on
manufacturers
adopted
the
single
wire
seal
approach
which
provided
significantly
higher
weather
resistance
and
thus
longer
service
lives.
Although
not
authentic
to
the
era
in
which
the
Z32
was
built,
the
move
to
this
harness
style
was
the
right
choice.
Many
new
replacement
parts
from
the
dealer
are
coming
this
way
now
and
it's
a
move
in
the
right
direction.
The
dip
switch
is
now
fully
sealed
with
a
conformal
silicone
boot
that
protrudes
through
the
urethane
potting
resin.
As
before,
it
selects
ADD
or
AVG
programming
with
the
direction
indicated
on
the
serial
number
label
above.
Versatile
Mounting
Fully
Immune
to
Interference
The
first
version
went
through
a
number
of
changes
to
address
the
threat
of
conducted
and
RF
power
from
high
frequency
HID
ballasts.
The
ultimate
rock
solid
solution
was
the
implementation
of
a
watchdog
timer
and
a
high
speed
startup
capability.
Starting
in
2012,
units
labeled
"WD1"
could
reset
themselves
in
less
than
the
time
between
cylinder
firings.
This
fix
has
been
proven
flawless
since.
The
2nd
gen
unit
carries
on
this
functionality
and
is
thus
also
fully
immune
to
the
electrical
environment.
Factory
Reprogrammability
The
removable
connector
provides
a
fully
encrypted
entry
point
for
factory
reprogramming
units
to
future
firmware
versions
that
can
include
added
functionality
or
other
enhancements.
I
should
emphasize
that
this
is
factory
reprogramming
and
updates
would
require
shipping
if
needed.
How
this
would
be
handled
needs
to
be
worked
out
in
the
future
but
the
functionality
is
there
now.
Plans
for
the
future...
blowthrough
mass
air!
The
thought
of
implementing
a
blow
through
sensor
arrangement
was
a
thought
before
the
first
translator
design
ever
made
it
to
silicon.
With
careful
calibration,
blow
through
mass
air
metering
can
be
very
accurate
and
repeatable.
For
blow
through
applications
others
in
the
aftermarket
have
found
that
the
blade
style
Hitachi
sensors
widely
adopted
by
Ford
produce
fantastic
results
and
are
long
term
stable
and
reliable.
In
a
collaboration
between
Selin
Design
and
Ashspec,
a
blowthrough
mass
air
metering
system
was
developed
for
placement
in
the
2.5"
Ashspec
intercooler
pipes
just
aft
of
the
intercoolers.
In
this
collaboration,
the
sensors
were
calibrated
for
the
translator
instead
of
the
translator
to
the
sensors.
The
result
is
compatibility
with
2nd
Gen
translators
sold
from
today
onwards
with
the
eventual
release
of
these
sensors.
An
extended
subharness
with
the
appropriate
connectors
will
be
available
through
my
new
site.
Ashspec
is
producing
sensor
housing
that
swap
cleanly
into
their
2.5"
piping
system
as
well
as
the
OEM
pipes
with
appropriate
adaptors.
The
release
of
this
option
was
supposed
to
coincide
with
the
2nd
gen
release
however
work
in
this
area
is
ongoing.
The
exact
timeline
is
TBD
but
it
is
definitely
upcoming.
But
there's
no
need
to
wait...
today's
inventory
is
future
proof!
Enjoy
dual
intake
power
and
add
a
blowthrough
kit
when
you
and
the
product
are
ready.
Ash
had
been
running
the
blowthrough
hardware
pictured
below
without
incident
since
mid
2013
and
report
fantastic
drivability
and
an
overall
positive
review.
