The
Wideband
FAILSAFE
Gauge
provides
the
ability
to
accurately
tune
AFR,
while
actively
protecting
your
engine
by
constantly
monitoring
AFR
curves
and
activating
a
user-defined
failsafe
strategy
if
it
runs
lean.
The
Wideband
FAILSAFE
Gauge
is
a
Universal
Exhaust
Gas
Oxygen
(UEGO"you-way-go")
controller
with
an
internal
boost
sensor,
an
internal
data
logger
and
a
full
color
Organic
Light
Emitting
Diode
(OLED)
display.
It
includes
technology
to
activate
a
failsafe
strategy
in
the
event
AFR
falls
outside
of
a
user-defined
operating
window.
If
the
AFR
falls
outside
of
the
set
operating
window,
the
Wideband
FAILSAFE
Gauge
triggers
a
user
defined
output
function
that
can
save
an
engine
from
catastrophic
damage.
WHY
YOU
WANT
ONE
This
product
is
a
must
have
for
all
tuned
performance
engines,
either
forced
induction
or
naturally
aspirated,
fuel
injected
or
carbureted.
Any
high
performance
vehicle
owners
who
want
a
highly
accurate
AFR
tuning
tool
with
logging
and
a
protection
strategy
that
can
save
an
engine
from
catastrophic
failure
will
want
this
FAILSAFE
device.
WHAT
IT
DOES
After
the
engine
is
tuned
and
a
safe
operating
window
of
AFR
is
established,
the
Wideband
FAILSAFE
Gauge
continually
monitors
AFR
and
boost
or
vacuum
to
make
sure
that
AFR
does
not
fall
out
of
the
defined
operating
window
at
a
given
boost
or
vacuum
level.
If
the
Wideband
Failsafe
detects
an
out
of
range
AFR
reading,
the
gauge
triggers
a
low
side
output
(ground
signal
with
a
1.5
amp
draw
max)
that
can
save
your
engine
from
catastrophic
damage.
Use
the
gauge's
intuitive
software
to
configure
the
low
side
output,
create
a
user-adjustable
time
delay
strategy
to
prevent
false
alarms,
and
customize
the
gauge
lighting
to
flash
and
alert
the
driver
if
an
alarm
is
triggered.
EXAMPLE
ENGINE
PROTECTION
STRATEGIES
NATURALLY
ASPIRATED,
TURBOCHARGED
OR
SUPERCHARGED
WITH
STAND
ALONE
EMS
OR
PIGGYBACK
CONTROLLER:
Use
the
low
side
output
to
cut
revs,
retard
timing,
trigger
a
separate
fuel
or
ignition
map
and
activate
an
ancillary
warning
light.
Users
with
turbos
can
also
trigger
the
device
to
cut
boost
(may
require
separate
solenoid).
The
aforementioned
strategies
are
provided
as
an
example.
Available
failsafe
strategies
will
ultimately
be
dependent
on
the
capability
of
the
EMS
or
piggyback
engine
controller.
