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 systemslike 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 andtransmission are deliveredseparately. The transmissionmust be attached to theengine by the installer.

We recommend the LS1Engine Installation Guide(part number 88959384),which illustrates basicprocedures and offershelpful tips on installing anLS engine older vehicles.

NOTE: Installing anelectronically controlledautomatic transmissionin an older vehicle with amechanical speedometerrequires an aftermarketsignal converter.
