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 drivability 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).
THE MAF MAY NOT HAVE A FLOW DIRECTION ARROW ON THE TOP. THE CORRECT ORIENTATION OF THE MAF IS AS SHOWN
BELOW:
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. Chevrolet Performance universal air inlet kit, P/N 19301246 is available for use
and meets all of the above requirements.
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
