Available I/O Typical Use Notes Component Wiring
Sensor Ground Isolated ground for
inputs. This is not the same as a
pow er ground or chassis
ground. This is shared for
the Fuel Press,
Air Tem p, MAP
(Manifold Press),
Ethanol Sensor,
etc. This should be w ired
to the ground pin of
the follow ing: Fuel
Press, Air Tem p,
MAP, and Ethanol
Sensor.
5V Reference 5 volt supply for the
follow ing aux inputs. When measured w ith a
voltmeter, it is normal to
not measure exactly 5V. This is shared for
the Fuel Press,
MAP (Manifold
Press), and
Ethanol Sensor
inputs. This should be w ired
to the voltage
reference pin of the
follow ing: Fuel
Press, MAP, and
Ethanol Sensor.
MAP (Manifold
Press)
Manifold pressure is used
for speed density fuel
calculation, ignition timing
correction, 02 feedback,
boost control, variable
valve control, ancillary
outputs, etc. Electronic fuel injection is
calculated in absolute
pressure not gauge
pressure. AEM carries MAP
sensors (sold
separately).
How ever, the
Infinity can accept
any 0–5V pressure
sensor and can be
calibrated in the
Infinity Tuner
softw are. This should be w ired
directly to the MAP
sensor's signal pin.
Ethanol Sensor This is used for
customers w ho are
converting their vehicle to
utilize ethanol fuels such
as E85 or E98. This digital input can be
used for other functions
as w ell. The GM Fuel
Composition Sensor
(FCS) is the most
commonly used for
converting a vehicle
to flex fuel. This pin needs to be
w ired directly to the
signal pin of the fuel
composition sensor.
Boost Control
Solenoid
This is used to operate a
12V PWM solenoid. Boost control solenoids
can be normally open (NO)
or normally closed (NC).
This w ill change the duty
cycle strategy but is also
depends upon how the
w astegate is plumbed
w ith hoses. AEM carries boost
control solenoids
(sold separately).
How ever, the
Infinity can control
most factory boost
control solenoids. Solenoids have tw o
w ires and have no
polarity.
Pow er from
Relay
Can be used for many
things, how ever, this 12V
source w as implemented
to be paired w ith the
Boost Control
Solenoid. This 12V is coming
through the vehicle's main
relay. Because of using
shared pow er, this
should only be used
for low current
electronics. N/A
High Side
Output
Can be used to activate
the 12V side of a solenoid If attempting to drive a
component over 4amps, a
relay must be used. The Infinity can
directly drive an
electronic
component up to
4amps max, such
as a boost solenoid. For a relay, this
should be w ired to
terminal 86 (or 85).
Supply chassis
ground to the
opposite terminal 85
(or 86). If directly
driving a low current
component, w ire this
to the 12V terminal.
