A precisely calibrated engine control module is essential to making your fuel-injected LT engine perform in your older vehicle - and Chevrolet Performance is your source for controllers that are designed for easy, 'plug-and-play' installation and, in most applications, no need for third-party tuning adjustments.
Unlike production controllers that may or may not come with a used engine, our controllers are calibrated for installation in older vehicles. That means many of the features required for late-model production vehicles are "turned off", because they're not required in older cars and trucks. That means features that may trigger a diagnostic trouble code and possibly affect performance - requiring additional tuning - are not enabled. Chevrolet Performance inclusive kits deliver all the components required to plug into the engine and get it running - from the controller itself and the accompanying wire harness to the mass airflow sensor, oxygen sensors and even a 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.Kit Includes:
- 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
- Fuel pressure sensor
- The programmed controller
- Instruction sheet
Each Chevrolet Performance controller kit is a true stand-alone system.
The all-new LT4 supercharged 6.2L V8 is the latest high-tech small-block crate engine from Chevrolet Performance. The perfect balance of performance and efficiency, the LT4 leverages the technologies introduced on the 2014 Corvette Stingray's LT1 Gen-V small block, including Direct Injection and continuously Variable Valve Timing. The LT4 is based on the same architecture as the LT1 engine, with several unique features designed to support its higher output and the greater cylinder pressures created by forced induction.

It includes the Rotocast A356T6 aluminum cylinder heads that are stronger and handle heat better than conventional castings, lightweight titanium intake valves and stronger forged aluminum pistons. While advancing the supercharging technologies established with the previous-generation Corvette ZR1's LS9 engine. This engine features the more-efficient, more-compact 1.7L Eaton R1740 TVS supercharger, which spins at up to 20,000 rpm. That's enough to generate more than 9 pounds of boost. The result is a surprisingly efficient engine capable of producing 650 horsepower and 650 lb-ft of torque. This LT4 crate engine is offered with a wet-sump or dry-sump oiling system. A controller specially designed for retro-fit application is available. There are also all-new transmission installation kits specially designed to match the LT4 and its 8-bolt crankshaft flange with Chevrolet Performances 4L-series four-speed automatic transmissions and the T-56 Super Magnum six-speed manual.LT4 376ci / 6.2L TECH SPECS:
