Haltech ECU & Engine Management Systems

What the Haltech Collection Covers

Standalone engine management for serious builds

Haltech provides standalone engine management for projects where a factory ECU no longer supports the engine, fuel system, boost level, or data needs of the build. The catalog includes ECUs, wiring, sensors, and interfaces that can be combined into a complete control system for street or race use.

Elite and Nexus ECU Platforms

Choose an ECU around the engine and build plan

Elite and Nexus platforms offer different levels of I O capacity, communications, and feature support. Select the ECU based on cylinder count, injector and ignition strategy, boost control needs, transmission integration, and expansion requirements rather than only the current horsepower target.

Plug and Play Harnesses

A clean route into supported platforms

Plug and play harnesses and application adapters make it easier to install compatible Haltech management on supported engines and vehicles. For custom engines, swaps, and race chassis, universal and terminated harnesses provide a more flexible starting point.

Boost Control and Inputs

Control and monitor the important systems

Boost control solenoids, pressure sensors, wideband interfaces, and input expanders help the ECU manage a forced induction combination with accurate information. Use compatible sensors and connectors so calibration data and wiring match the selected system.

CAN Data and Dash Integration

Keep electronics communicating

CAN adapters, gauge interfaces, camera kits, and auxiliary modules expand the data available to the driver and tuner. Planning CAN connections early helps prevent wiring duplication and makes future upgrades easier.

Wiring and Installation Planning

Build the system before installation

A complete ECU plan includes power distribution, grounding, injector and ignition connectors, sensors, relay control, and safe harness routing. Confirm the desired ECU connector type and wiring approach before ordering to avoid mixing incompatible parts.

• Decide whether a plug and play harness or custom harness is needed
• Plan boost control and wideband requirements
• Confirm transmission interface needs before choosing the ECU
• Check the required CAN devices and gauge connections
• Match connectors and harness terminals to the selected system
• Plan safe power, ground, relay, and fuse routing
• Work with a qualified calibrator for initial setup and tuning
• Leave capacity for future sensors and performance upgrades

Common Questions

What is a standalone ECU?

A standalone ECU is a programmable engine controller that can replace or supplement factory engine management for a compatible performance build.

Which Haltech ECU should I choose?

Choose the ECU based on engine configuration, injector and ignition control, required inputs and outputs, boost control, transmission needs, and future expansion plans.

Do I need a custom wiring harness for Haltech?

Some supported applications use plug and play harnesses. Custom engines, swaps, and race chassis commonly use terminated or universal harnesses.

Can Haltech control boost?

Compatible Haltech systems can control boost when paired with the appropriate boost control solenoid, sensors, wiring, and calibration.

What is a CAN adapter used for?

A CAN adapter allows compatible electronic devices to share data with the ECU or other modules through the vehicle communication network.

Can I use Haltech on an LS swap?

Haltech offers components that support custom engine projects including LS swaps. Select ECU and harness hardware around the specific engine and vehicle integration needs.

Do I need a wideband with a standalone ECU?

A wideband is strongly useful for monitoring air fuel ratio and supporting accurate calibration. Confirm interface compatibility with the chosen ECU.

What does a terminated harness do?

A terminated harness provides pre configured connectors and wiring ends to reduce assembly time for a custom ECU installation.

Can I add sensors later?

Expansion modules and available ECU inputs can support added sensors later, but planning capacity before wiring the vehicle makes upgrades simpler.

Does an ECU require professional tuning?

A qualified tuner should configure and calibrate the ECU for the specific engine and hardware combination to support reliable operation.
