This control system is a stand alone, fully-integrated kit designed to run all Chevrolet Performance LT1 based crate engines with 58x crankshaft reluctor
wheels, 4x camshaft indexing, and electronic throttle control (ETC). This engine control kit is designed to operate a "GEN 5" V8 only, it is not designed
to operate any earlier engine configurations. Included in the kit are the engine control module (flashed with the appropriate calibration), Fuel Pump
Power Module, engine harness, accelerator pedal, mass air flow (MAF) sensor, MAF sensor mounting boss, Fuel Line Pressure Sensor, oxygen sensors
(2), and oxygen sensor mounting bosses (2). This control system is intended for use with a returnless fuel system and fuel pump that is capable of being
pulse width modulated (PWM) at 25 kHz to control fuel pressure. A fuel flow rate of 45 gph at 72 psi (500 kPa) is needed. Because this is a dead headed
system, a pressure relief set at 84 psi (580 kPa) must be included in the fuel line between the tank pump and the engine mounted high pressure pump.
Chevrolet Performance Part Number 19303293 is one example of a compatible fuel pump and it includes an internal pressure relief system. If using
this pump, the lower port on the module may be left open or used to connect a remote pick up system. P/N 13587174 is connector pigtail for this
pump and is available from your local dealer.
A pump with excessive capacity may result in cavitation at low flow due to the pump repeatedly stopping and starting instead of controlling to a
speed/pressure. Alternatively, a fuel system operating at a fixed 72 psi (500 kPa) could be used and a fuel pump relay may be triggered by the
Green/Gray wire in cavity 2 of the Fuel Pump Power Module (FPPM) connector. The Green/Gray wire is 12 volt positive side control for a fuel pump
relay. Do not use or install the Fuel Pump Power Module if using this alternate method. Diagnostic codes will be set in the ECM if the FPPM is not
used, but will not illuminate the MIL (malfunction indicator light). Note that excessive fuel heating and potential startability/drivability issues may
result from a constant high pressure.
IMPORTANT: Read the 'System DOs and DON'Ts' section below before attempting to install the engine and then review again before attempting to
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 (2014 - 2015 Corvette).
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.
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.

Use an adjustable fuel pressure regulator to ensure the fuel pressure supplying the high pressure pump on the engine is a minimum 45 gph @
72 psi (500 kPa).

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 the Fuel Line Pressure Sensor is installed properly.
