AEM's
X-Series
OBDII
Wideband
UEGO
AFR
Sensor
Controller
Gauge
(PN
30-0334)
provides
tuners
who
are
using
piggyback
tuning
modules
or
open
source
software
with
the
ability
to
view
AFR
through
the
factory
CAN-bus
stream
that
is
output
by
the
factory
ECU,
and
deliver
the
most
accurate,
safe
and
powerful
tune.
The
30-0334
X-Series
OBDII
Wideband
Gauge
is
validated
to
work
with
EFILive,
HPTuners
and
DashDaq
software.
The
X-Series
Wideband
AFR
OBDII
Gauge
includes
an
OBDII
pass-through
connector
and
Bosch
4.9LSU
sensor
that
can
be
free-air
calibrated
or
used
with
the
factory
resistor
calibration.
Additional
wiring
for
a
0-5v
or
RS232
Serial
output
can
be
added
by
the
user
for
outputting
to
a
data
logger.
This
OBDII
pass-through
capability
replaces
the
traditional
AEMnet
stream
available
in
the
30-0300
X-Series
Wideband
AFR
Gauge
Controller.
OBDII
CAN-bus
OUTPUT
The
OBDII
output
simulates
an
auxiliary
ECU
signal
when
plugged
into
a
vehicle’s
OBD
port,
which
requires
a
unique
address
from
the
other
ECUs
already
on
a
vehicle’s
network.
AEM’s
default
OBDII
CAN
address
will
work
with
most
popular
vehicles
and
adjustments
should
not
be
necessary.
However,
AEM
has
provided
OBDII
address
programmability
through
the
buttons
on
the
gauge
face
if
a
different
address
other
than
the
default
address
is
required,
allowing
users
to
program
ECU
#,
Parameter
Identification
(PID),
Message
Identifier,
and
Bit
Rate.
PATENTED
X-DIGITAL
TECHNOLOGY
–
It’s
The
Fastest
X-Series
Widebands
are
the
fastest
responding
wideband
air/fuel
ratio
controllers
in
independent
testing
against
17
other
wideband
UEGO
air/fuel
controllers.*
The
controller’s
high
speed,
patented,
X-Digital
technology
(Patent
9,575,030)
ensures
no
loss
of
signal
fidelity
and
full
transient
response,
making
it
able
to
identify
the
slightest
fluctuations
in
AFR
and
output
them
in
full
value.
WHY
RESPONSE
TIME
MATTERS
Faster
response
time
improves
wideband
feedback
control,
and
can
provide
a
safer,
more
powerful
and
accurate
tune.
AEM’s
Wideband
Controllers
with
X-Digital
technology
reduce
deadtime
and
can
improve
the
performance
of
your
vehicle
through
more
accurate
AFR
tuning.
FACTORY
CALIBRATION
RESISTOR
OR
FREE-AIR
CAL,
IT’S
YOUR
CHOICE!
X-Series
Wideband
Gauges
and
the
X-Series
Inline
Controller
support
the
popular
Bosch
4.9LSU
sensor,
and
can
utilize
both
the
factory
calibration
resistor
and
free-air
calibration
methods.
This
allows
users
to
take
advantage
of
the
precise
factory
resistor
calibration
when
a
sensor
is
new
but
then
allows
for
free-air
calibrations
if
the
user
desires
when
the
sensor
ages.**
It’s
the
perfect
marriage
of
simplicity
and
accuracy!
WHAT
IS
A
WIDEBAND
UEGO
AIR/FUEL
CONTROLLER?
AEM's
Wideband
UEGO
(Universal
Exhaust
Gas
Oxygen,
pronounced
“You-Way-Go”)
Controllers
are
powerful,
cost
effective
tuning
tools
that
allow
users
to
accurately
monitor
the
Air/Fuel
Ratio
(AFR)
of
their
engine.
WHY
USE
A
WIDEBAND
AIR/FUEL
CONTROLLER?
Accurate
AFR
data
is
critical
when
tuning
an
engine.
Running
rich
(very
low
air/fuel
ratio,
excessive
fuel)
can
cause
a
loss
in
power,
while
running
too
lean
(very
high
air/fuel
ratio,
not
enough
fuel)
may
result
in
serious
engine
damage.
Using
a
wideband
air/fuel
controller
during
the
tuning
process
allows
you
to
monitor
AFR
and
adjust
tuning
parameters
to
optimize
them
for
maximum
power
and
efficiency.
AEM
has
a
comprehensive
line
of
highly
accurate,
reliable
wideband
air/fuel
controllers
that
can
help
ensure
your
vehicle
is
optimally
tuned.
CAN
I
CHANGE
THE
AEM
UEGO
SENSOR’S
CONNECTOR?
No.
There
is
a
laser-etched,
calibrated
resistor
in
the
sensor’s
connector
body.
This
resistor
is
specifically
created
for
the
exact
sensor
that
it
is
attached
to.
Modifying
this
will
invalidate
the
sensor’s
output.

**
Wideband
UEGO
sensors
are
wear
items
and
their
lifespan
is
determined
by
many
factors
including
contamination
from
leaded
fuels,
automotive
fluids,
particulates,
mechanical
or
thermal
shock
and
from
being
unheated
and
exposed
to
the
exhaust
stream.
Free-air
calibration
may
correct
drift
as
a
sensor
ages,
but
it
is
recommended
that
they
are
replaced
as
part
of
your
vehicle’s
maintenance
program.
When
performing
free-air
calibration,
please
follow
the
procedure
outlined
in
the
instruction
manual.
