About our engine controllers and SuperMaticTM transmission controllers

The engine and SuperMatic transmission controllers in the “Connect & Cruise” Crate Powertrain kits are designed for true stand-alone performance in older vehicles. All that’s needed to get a vehicle running with the engine controller is power and ground sources, a high-pressure fuel pump and an electric cooling fan.
For the LS3, we recommend a 58-psi (400 kPa) fuel pump and for the LSA, a 65-psi (450 kPa) pump.
Chevrolet Performance’s specially calibrated engine controller will give the same performance as the production engine but does not utilize a number of features associated with production-model systems like ECM controlled start, AC control or cruise control. It also includes a SES (service engine soon)LED indicator embedded in the fuse box as well as an electical lead for an optional dash mounted SES indicator. This system uses enhanced OBD 1 style diagnostic codes. The SuperMatic transmission controller is the most fully integrated and user-friendly transmission control system on the market. Only a few connections are required to get the transmission ready for operation in you vehicle – and it is designed for tuning-free compatibility for the Crate Powertrain systems’ engine control module.

NOTE: The engine and transmission are delivered separately. The transmission must be attached to the engine by the installer.

We recommend the LS1 Engine Installation Guide (part number 88959384), which illustrates basic procedures and offers helpful tips on installing an LS engine older vehicles.

NOTE: Installing anelectronically controlled automatic transmissionin an older vehicle with a mechanical speedometer requires an aftermarket signal converter.

Each kit delivers a brand-new, fully assembled crate engine, a brand-new electronically controlled overdrive transmission, electronic control modules for both, and the engine control hardware to get it all running in your project vehicle – including the mass airflowsensor, oxygen sensors and even the special throttle pedal for the engines’ electronic throttle bodies.

Chevrolet Performance engineers matched the engines with their respective transmission, ensuring it was up to the task of channelling big power with absolute dependability. The engine controller is specially calibrated to run the engine withoutsome of the production-vehicle features that aren’t required in an older vehicle. That means no need for third-party tuning. Better still, the systems’ unique SuperMatic™ transmission controller is designed to work with the engine controller for a seamless,“plug and play” installation that is quick, easy and intuitive.
