Chevrolet Performance Crate Engine Control System Mode D'emploi

5.3L Crate Engine Control System
Thank you for choosing Chevrolet Performance as your high performance
source. Chevrolet Performance is committed to providing proven, innovative
performance technology that is truly.... more than just power. Chevrolet
Performance parts are engineered, developed and tested to exceed
your expectations for fit and function. Please refer to our catalog for the
Chevrolet Performance Authorized Center nearest you or visit our website

This control system is a stand alone, fully-integrated kit designed to run 5.3L
Chevrolet Performance crate engines with 58x crankshaft reluctor wheels,
4x camshaft indexing, and electronic throttle control (ETC). Included in the
kit are the engine control module (flashed with the appropriate calibration),
engine harness, accelerator pedal, mass air flow (MAF) sensor, MAF sensor
mounting boss, oxygen sensors (2), and oxygen sensor mounting bosses
(2). This control system requires a fuel system which maintains 400 kPa
(60 psi) constant pressure and can deliver 40 gph for the 5.3L. Vehicle
performance/driveability and engine durability may be affected if the correct
pressure or flow are not maintained.
IMPORTANT: Read the "System DOs and DON'Ts" section below
before attempting to install the engine and then review again before
attempting start the vehicle. Note that if the engine will not come off
idle after the control system installation, check for an illuminated MIL
(malfunction indicator light, which is located in the fuse/relay center,
sometimes called the "Check Engine Light" or "Service Engine Soon"
light) which indicates stored fault codes. Check for codes and make
any required repairs if the MIL is illuminated (typically it is a connector
issue or a wiring issue), consult a service manual if necessary (Use
information from GM Performance Parts Diagnostics 2007- 2011
Chevrolet Silverado Truck for the 5.3L engine).
Observe all safety precautions and warnings in the service manuals
when installing this package in any vehicle. Wear eye protection
and appropriate protective clothing. Support the vehicle securely
with jack stands when working under or around it. Use only
the proper tools. Exercise extreme caution when working with
flammable, corrosive, and hazardous liquids and materials. Some
procedures require special equipment and skills. If you do not have
the appropriate training, expertise, and tools to perform any part of
this conversion safely, this work should be done by a professional.
System DOs and DON'Ts:
Do:
• Ensure all intended engine/vehicle side connections are made before
connecting ignition or battery power to the system.
• Ensure the wiring harness is secured as required, and that the routing
avoids locations which can potentially damage the wiring (e.g.: sharp
edges, pinch points, rotating components, exhaust components, etc.).
Make sure any unused connectors or wiring are properly secured and
protected (sealed or taped as required to avoid short circuiting).
• Ensure all engine and wiring harness grounds are clean and secure.
Minimum ¾ inch braided strap from the engine to the vehicle chassis
is recommended.
• Ensure the MAF sensor is oriented correctly in the induction (it will
only read correctly in the proper direction). An arrow is located on the
sensor indicating correct flow direction. Verify this before welding the
mounting boss, as the sensor will mount only one way in the boss.
• Ensure the MAF Sensor is mounted in the middle of a minimum 6 inch
length of 4 inch diameter tube, and is a minimum of 10 inches from the
throttle body.
• Ensure the fuel pressure is a constant 400 kPa (60 psi) with the engine
running. This is what the control system has been developed to run.
5.3L Crate Engine Control System
TITLE
• Ensure the fuel pump has the following flow capability: Minimum
40 gph @ 400 kPa for LC9 5.3L.
• Ensure battery voltage is connected using a minimum 8 gauge wire to
one of the studs on the fuse block.
• Ensure that the accelerator pedal clearances meet the guidelines
below.
• Ensure that the oil pressure sensor connects to your engine wiring
harness. If the connector doesn't fit, install the provided oil pressure
sensor and torque to 35 N·m (26 lb-ft).
Don't:
• Change or alter any wiring in the accelerator pedal or electronic
throttle systems.
• Vacuum reference the fuel system, it must run constant
400 kPa (60 psi).
• Solder or alter any Oxygen Sensor wiring.
Vehicle Requirements
Vehicle Speed Input - optional
The ECM is programmed and looking for 40 pulses per revolution typical
for automatic transmissions. The 5.3L harness is designed to plug into
the output speed sensor of 4L60 & 4L80 Transmissions, which have a
40 pulse output. NOTE: If you are using the CP Supermatic Connect
and Cruise Transmission Control System, the vehicle speed input
must be plugged in.
Axle Ratio and Tire Size Requirements
The axle drive ratio in the calibration is set to 3.42:1 and is okay for
ratio from 3.08 to 4.11. Tire diameter needs to be between 26" and 30".
NOTE: For optimal performance choose an axle ratio and a tire size
within the recommended range.
NOTE: All Engines are shipped with an automatic transmission
flex plate. For manual applications, the clutch and flywheel used
must be purchased separately and is up to the end user. See

flywheels.
Also see the CP Catalog or
recommended starter, flywheel and clutch components.
