Chevrolet Performance E-ROD LS3 6.2L Mode D'emploi

E-ROD Crate Engine Control System
Chevy Performance Parts - E-ROD Crate Engine
Catalytic
Converter
Emissions Canister
This control system is a stand alone, fully-integrated kit designed to run
Chevrolet Performance Parts E-ROD 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 for the Low Emissions series engine used), engine
harness, accelerator pedal, mass air flow (MAF) sensor, MAF sensor
mounting boss, oxygen sensors (4), and oxygen sensor mounting bosses
(4). This control system requires a fuel system which maintains 400 kPa
(60 psi) constant pressure and can deliver 40 gph for the LC9 & LS3
engines. 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.
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.
• Ensure the fuel pump has the following flow capability: Minimum 40 gph

• 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.
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
Maximum Vehicle GVWR (Gross Vehicle Weight Rating)
5.3L LC9 Engine 7200 lbs or less
6.2L LS3 Engine 5725 lbs or less
Vehicle Speed Input Requirement
The vehicle Speed Sensor input from your transmission of choice is required.
This signal is mandatory for emissions compliance. The ECM is programmed
and looking for 40 pulses per revolution typical for automatic transmissions
(40T calibration) and 17 pulses per revolution on typical manual transmis-
sions (17T calibration). You will need to know what the signal output of your
transmission of choice is before ordering you E-ROD. The E-ROD harness
is designed to plug into the output speed sensor of 4L60 and 4L80 transmis-
sions, which have a 40 pulse output.
NOTE: Some manual transmissions have 40 pulses per revolution
output.
Axle Ratio and Tire Size Requirements
The axle drive ratio in the calibration is set to 3.42:1 and is ok 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
with-in the recommended range.
NOTE: All Engines are shipped with an automatic transmis-
sion flex plate. For manual applications, the clutch and flywheel
used must be purchased separately and is up to the end user.
