Installation Instructions:
ECM
The Engine Control Module (ECM) is environmentally sealed and
can be mounted under hood, however, avoid extremely hot locations
(exhaust, etc.) or high splash areas. It is not recommended that the
ECM be mounted directly to the engine.
Accelerator Pedal
Mount the accelerator pedal per the following dimensional guidelines,
mounting details are application-specific and are left to the user.

Ensure that the pedal is securely mounted to the vehicle. A grommet
is required in any sheet metal hole that the harness routes through to
avoid wire damage.
Mass Air Flow (MAF) Sensor
NOTE: It is critical that the MAF sensor is mounted per the
instructions below. Vehicle performance and/or driveability may
be affected if it is not mounted as recommended.
The mass air flow sensor must be installed in the induction system
using the supplied MAF sensor mounting boss. The induction system
should be 4 inches in diameter and have a minimum straight section
6 inches in length. Mount the MAF sensor in the middle of the straight
induction section, ensuring that the middle of the mounting boss is at
least 10 inches from the throttle body.
The MAF sensor must be oriented correctly in the induction
system – note the arrow on the sensor indicating flow direction.
Be sure to weld the mounting boss correctly—the sensor will
only mount one way in the boss (see diagram).

MAF SENSOR MOUNTING BOSS
Weld the boss in place before installing the sensor. When installed in
the vehicle, the MAF sensor should be mounted with the connector
end pointing between horizontal and fully upright—do not mount with
the connector oriented downward.
Air Cleaner
It is recommended that a dry element air cleaner be used.
NOTE: Fueling cannot be guaranteed if an oiled element type
air cleaner is used.
Oxygen Sensors
NOTE: It is critical that the Oxygen Sensors are mounted per
the instructions below. The exhaust system MUST be properly
sealed – any leak near the sensors (upstream or downstream)
can cause incorrect operation of the fuel control system. Vehicle
performance and/or driveability may be affected if sensors are
not mounted as recommended or if an exhaust leak exists. Leak
check the exhaust system to ensure adequate sealing (even
small leaks can affect fuel control).
Tunnel
Oxygen sensors should be mounted in the collector area of the
Console
exhaust pipe, in a location that allows exhaust from all cylinders to
be sampled equally. Be sure the connectors and wiring are routed
away from high heat areas. The oxygen sensors should be mounted
with the sensor tip pointing between horizontal and fully downward
– do not mount with the tip oriented upward. Weld in the mounting
bosses supplied (7/8" hole) if using headers.
Exhaust Manifolds
It is recommended that you use the provided exhaust manifolds or
similar LS Engine style Exhaust Manifolds.
Positive Crankcase Ventilation System (PCV)
How to set up your PVC system:
There are two ports on the engine that make up the PCV system.
The ports on the engine are:
1) Left rear (driver side) valve cover
2) Right Front (passenger side)
The ports with silver tubes may look simple but, they should not be
modified. The tubes have a small orifice within them that is used
in place of a PCV valve of earlier designs. These ports must be
connected to filtered clean air. This connection must be within the
engines air cleaner system and must be between the MAF (Mass
Air Flow Sensor) and engine's throttle body. The engine burns the
air that enters the PCV system so, if the fresh air port is prior to the
MAF then, this air will enter the engine without being measured by
the MAF and adverse engine operation may occur.
