There
are
two
ways
to
program
the
STAG
‐
4
controller:
Programming
with
the
petrol
and
LPG
maps.
See
to
Manual
programming
of
the

See
Programming
with
the
petrol
and
LPG
maps
consists
of
the
following
stages:
Auto
‐
calibration
of
the
STAG
‐
4
controller
Collection
of
the
petrol
injection
times
with
petrol
(petrol
map)
Collection
of
the
petrol
injection
times
with
LPG
(LPG

Making

both
maps
match
and
checking
deviations
3.1.
Auto
‐
calibration
Prior
to
starting
the
auto
‐
calibration,
start
the
engine
and
wait
until
the
lambda
probe
begins
to
work.
During
the
auto
‐
calibration
the
engine
should
work
at
idle
run;
do
not
increase
rpm,
switch
off
air
‐
conditioning
and
lights
and
do
not
turn
the
steering
wheel
as
this
may
cause
errors
during
the
auto
‐
calibration.
During
the
auto
‐
calibration,
watch
carefully
petrol
and
LPG
injection
times.
If
LPG
injection
times
are
shorter
than
petrol
injection
times,
the
injector
nozzles
may
be
too
large
and
should
be
replaced
with
smaller
diameter
ones.
When
the
auto
‐
calibration
is
complete,
2
extreme
yellow
points
and
4
additional
points
in
between
will
show
up
on
the
multiplier
map.
The
second
left
point
is
the
point
of
engine
operation
at
idle
run
i.e.
the
point
of
operation
during
auto
‐
calibration.
The
multiplier’s
value
for
this
point
should
be
between
1.1
and
1.6;
if
the
value
is
greater
than
1.6,
longer
times
of
petrol
injection
i.e.
greater
load
and
high
rpm,
may
cause
overlapping
of
injection
times
i.e.
one
LPG
injection
will
begin
before
the
previous
one
ends
(looped
injections).
In
such
a
case,
the
controller
will
display
the
„Too
long
injection
time”
error
message.
However,
in
such
a
case,
check
the
operation
of
the
lambda
probe;
if
it
is
in
the
“rich”
mode
and
the
vehicle
drives
without
problems,
the
error
can
be
ignored.
3.2.
Collection
of
the
petrol
injection
map
with
petrol
(petrol
map)
Having
finished
the
auto
‐
calibration,
switch
over
to
petrol
and
drive
the
vehicle
for
app.
4
km
to
collect
the
petrol
map.
During
the
collection
of
the
map
try
to
drive
without
changing
gears
e.g.
at
the
4
th
gear
and
in
a
way
making
the
lambda
probe
to
“work”
i.e.
changing
its
mode
from
weak
to
rich.
Blue
points
should
appear
during
the
collection
of
the
map.
To
collect
the
map
quicker,
adjust
vehicle
load
in
such
a
way
causing
new
points
to
be
collected
in
places
which
are
still
empty.
Collection
of
maps
is
performed
without
participation
of
the
diagnostic
software,
thus
can
be
done
with
the
PC
disconnected.
However,
collecting
the
map
while
the
PC
is
connected
and
the
diagnostic
software
running
is
quicker
and
enables
the
operator
to
see
what
is
actually
happening
to
the
vehicle.
When
the
controller
collects
sufficient
number
of
points,
the
map
will
be
drawn
with
a
continuous
line
and
the
petrol
map
collection
is
finished.
