These control systems are designed to operate the DR-525 engines and are strictly for off road usage. The 19421202 and 19432870 kits must be
used with C10 fuel or equivalent. The use of pump fuel will cause severe engine damage.
This control system is a stand alone, fully-integrated kit designed to run the Chevy Performance DR-525 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 and locked with the
appropriate calibration), engine harness, accelerator pedal, mass air flow (MAF) sensor, MAF sensor mounting boss, MAF mounting screws and
washers (2), 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. Vehicle performance/drivability 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 Chevy Performance Diagnostics, 2006- 2011 Cadillac CTS, 2006 – 2010
Corvette or 2010-2011 Camaro).
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.
•
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.
•
Ensure the fuel pump has the following flow capability: Minimum 40 gph @ 400 kPa (60 psi).
•
Ensure battery voltage is connected using a minimum 8 gauge wire to the horizontal stud on the fuse block.
•
Ensure that the accelerator pedal clearances meet the guidelines below.
Don't:
DO NOT OPERATE EITHER DR-525 C10 KIT WITH "PUMP" FUEL.
•
•
Do not attempt to alter the ECM calibration or software. Any attempt to interrogate the ECM will result in ECM mal function.
•
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.
