Chevrolet Performance LS Controller Kit - LS3 430BHP

Engine Management System: LS3 Controller Chevy 6.2L Kit for 430 BHP Engines

The engine control module is the brain of your Gen IV LS- or Gen V LT-powered project vehicle. Chevrolet Performance is your source for controllers designed for easy “plug-and-play” installation. In most applications, there is no need for third-party tuning adjustments.

Unlike controllers from regular-production vehicles, which may or may not come with a used engine, Chevrolet Performance controllers are uniquely calibrated for installation in older vehicles. That means many features required for late-model-production vehicles are “turned off,” because they’re not required in older cars and trucks. That prevents the unnecessary triggering of diagnostic trouble codes that could possibly affect performance or require additional calibration adjustments.

Our inclusive kits deliver all of the components required to get the engine and transmission up and running - from the controller itself and the accompanying wire harness to the mass airflow sensor, oxygen sensors and electronic throttle pedal assembly for engines equipped with an electronic throttle body. The kits also include detailed instructions to help you do it right the first time, even if you have no experience.

Most kits include:

• Two oxygen sensors

• Two oxygen sensor mounting bosses (for installation in the exhaust system)

• A mass airflow meter

• A mass airflow meter mounting boss (for installation in the air intake system)

• A throttle pedal assembly (for use with the electronically operated throttle)

• A specific oil pressure sensor that is compatible with the harness (when needed)

• A complete wiring harness with fuse-box and necessary cam sensor and MAP sensor jumpers

• Fuel pump power module for direct-injected engines

• Fuel pressure sensor for direct-injected engines

• Instruction sheet

Each Chevrolet Performance controller kit is a true stand-alone system: All that’s needed to get a vehicle running with it are power and ground, a high-pressure fuel pump and a throttle pedal controller.

⚙ QUICK INSTALLATION TIPS

INSTALLING THE ECM – The ECM is weather-resistant and can be mounted under the hood, but it should be placed to avoid extreme heat and away from any exhaust system. Chevrolet Performance does not recommend mounting it directly to the engine.

ACCELERATOR PEDAL – Chevrolet Performance’s controller kits are designed for use with factory-type electronic throttles (no conventional throttle cable) that require a matching accelerator pedal. The pedal contains an electronic sensor that’s connected to the controller via harness mount up to connect the throttle. The pedal should be mounted about 2.5 inches to the right of the brake pedal and 2 inches below it. There should be at least 75–76mm clearance between the top of the pedal pad and the transmission tunnel/centre console. The pedal has a wire harness connection that must go through the firewall—possibly requiring a new hole. Use the included template to assist with placement.

MAF – The mass airflow meter that comes with some controller kits must be mounted in a 4-inch-diameter tube that has at least a 6-inch-long straight section. The airflow meter should be mounted approximately 10 inches ahead of the throttle body. The airflow sensor should be at the centre of the straight section, making sure that at least 10 inches of the tube ahead of the sensor are straight for proper operation. The meter’s sensor should be mounted with the connector pointed horizontally.

OXYGEN SENSORS – The two oxygen sensors (one for each side of the exhaust) must be inserted in the exhaust stream ahead of the catalytic converters (if used). Holes are simply drilled into the exhaust tubing and the mounting bosses welded to them. After that, the oxygen sensors simply screw onto the mounting bosses and are connected to the wire harness.
