This control system is a stand alone, fully-integrated kit designed to run Chevrolet Performance LT4 series 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 65.6 G/H at 58 psi (400) 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 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.
DIFFERENT KITS USE DIFFERENT HARNESSES, EVEN THOUGH THEY LOOK THE SAME. EACH HARNESS IS UNIQUE TO A
MODEL YEAR ENGINE. CHECK WITH YOUR DEALER IF YOU HAVE QUESTIONS.
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
(2016 Cadillac CTS-V).
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.
