LT4 engine controller ECU and harness for use with 8L90E eight speed automatic transmission package

This engine controller package Includes all components needed to run Chevrolet Performance LT4 crate engines with the Chevrolet Performance 8L90E eight speed automatic transmission. Includes E-92 controller, fuel pump power module and fuel pressure sensor for direct injection.

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, Chevrolet Performance 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.
