Master Dash
The Master Dash is designed for easy viewing of all sensors and user accessible values. For example,
this dash may be used as an overview to quickly verify that all sensors are reading expected values.
Also note that the ignition timing-related values are given along the bottom of the Master Dash – the
three component parts as well as the end result.
Base Idle Adv + Vacuum Adv = Total Timing

DESCRIPTION
AFR
Air/Fuel
Ratio.
The
reading
from
the
wideband
oxygen
sensor.
Air
Temp
This
is
the
temperature
of
the
air
entering
the
throttle
body.
It
can
be
displayed
in
either
Fahrenheit
or
Celsius.
Base
Timing
Ignition
timing
value
taken
from
the
main
RPM
‐
based
timing
curve.
This
makes
up
one
part
of
the
final
timing
value
the
engine
sees.

Timing
Timing
related
data
is
only
valid
when
EZ
‐
EFI®
is
controlling
timing.
Battery
Battery
voltage.
Coolant
Temp
This
is
the
temperature
of
the
engine.
It
can
be
displayed
in
either
Fahrenheit
or
Celsius.
FP

Duty
cycle
of
the
fuel
pump
control
output.
With
a
returnless
‐
style
fuel
system,
this
goes
up
and
down
to
raise
and
lower
fuel
pressure.
With
a
return
‐
style
fuel
system,
this
remains
at
100%
when
the
fuel
pump
is
running.
Fuel
Pressure
Fuel
pressure
in
psi.
It
is
normal
for
this
to
rise
and
fall
with
varying
engine
load.
Fuel
pressure
will
be
lower
at
idle
and
in
normal
driving
when
there
is
the
more
vacuum
in
the
intake
manifold.
Fuel
pressure
will
rise
as
the
engine
approaches
wide
open
throttle.
This
is
true
of
both
return
and
returnless
style
fuel
systems.
IAC
Idle
Air
Control.
This
is
the
position
of
the
idle
motor.
At
idle,
it
will
move
around
to
maintain
the
target
idle
speed.
Displayed
in
“counts”.
Higher
counts
mean
the
idle
motor
is
open
more
and
allowing
more
air
to
bypass
the
throttle
blades.
Its
range
is
from
5
to
180.
Generally,
this
will
be
around
20
idling
out
of
gear
with
a
fully
warmed
‐
up
engine.
