This publication provides general information on components and procedures which may be useful when installing or servicing your crate engine.
Please read this entire publication before starting work
The LT4 E-ROD crate engine system includes an engine control system with everything needed to operate the engine. It is not the intent of these
specifications to replace the comprehensive and detailed service practices explained in the Chevrolet service manuals. For information about warranty
coverage, please contact your local Chevrolet Performance Parts dealer. Observe all safety precautions and warnings in the service manuals when
installing a crate engine in any vehicle. Wear eye protection and appropriate protective clothing. When working under or around the vehicle support it
securely with jack stands. 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. This publication is intended to provide information about this crate engine and
related components. This manual also describes procedures and modifications that may be useful during the installation of an LT4 E-ROD crate engine
system. It is not intended to replace the comprehensive service manuals and parts catalogs which cover Chevrolet Performance engines and
components. Rather, it is designed to provide supplemental information in areas of interest to "do-it-yourself" enthusiasts and mechanics
IMPORTANT: Read the "System Dos and DON'Ts' section below before attempting to install the engine and then review it again before
attempting to start the engine. 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
wiring issue), consult a service manual if necessary.
System Dos and DON'T's
DO:
•
Ensure all intended engine/vehicle electrical 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 location 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 air 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.
•
The FPPM (Fuel Pump Power Module) must be used to control the supply fuel pump. The fuel supply system should be a returnless
style to reduce the internal temperature of the fuel. Not using the FPPM will cause diagnostic codes to be set.
•
Ensure battery voltage is connected using a minimum 8-gauge wire to one of the studs on the fuse box as directed.
•
Ensure the accelerator pedal clearances meet the guidelines below.
•
Ensure the Fuel line Pressure Sensor is installed properly.
•
Once the engine is warmed up, oil pressure step changes of 10 psi or more may be seen without any RPM change. This is a normal
operating condition used for diagnostic purposes.
