The
Infinity
ECU
delivers
state-of-the-art
electronic
fuel
injection
(EFI)
control
technology
which
provides
durability,
flexibility
and
capabilities
typically
found
only
at
upper
echelons
of
Motorsports.
We
have
now
made
this
technology
affordable
for
both
professional
race
teams
and
amateur
racers.
Built
around
a
latest-generation
200MHz
automotive
processor,
the
Infinity
ECU
is
capable
of
processing
400
MIPS
(millions
of
instructions
per
second)
and
is
perhaps
the
fastest
ECU
available
today.

AIRFLOW
MODEL
BASED
CALCULATIONS
Infinity's
airflow
model
based
systems
greatly
reduce
the
amount
of
time
it
takes
to
set
up
and
tune
an
engine
by
eliminating
many
of
the
lookup
and
trim
tables
(correction
tables)
necessary
in
previous
generation
ECUs.
USER
INTERFACE
SOFTWARE
InfinityTuner
is
optimized
for
speed
and
performance.
The
software
has
the
power
to
control
a
multitude
of
features
found
in
today's
modern
racecars,
and
features
an
advanced
tuning
Wizard
to
reduce
set
up
time.
ULTRA-HIGH
RESOLUTION
FUEL
CONTROL
The
Infinity
ECU
calculates
injector
pulsewidth
in
units
of
1/10th
of
a
microsecond
(0.0000001
second).
Individual
cylinder
fuel
trim
is
included
and
user
adjustable
vs.
engine
RPM.
ACCURATE
IGNITION
TIMING
UNDER
ANY
CONDITION
InfinityTuner
software
features
several
3D
ignition
trim
maps
(coolant
and
air
temp
based),
and
its
back-end
timing
code
is
tested
to
100,000
RPM.
Individual
cylinder
ignition
trim
is
included
and
is
user
adjustable
vs.
engine
RPM.

addition
of
an
ethanol
content
sensor
(sold
separately)
