The CORE ECU is HP Tuners' first standalone engine computer, built for enthusiasts and professionals who want real-time tuning, 16-injector support and full data logging. Whether you're building a drag car, road racer, drift car or restomod, CORE is made to deliver precision, power and reliability.

Key features

• Supports up to 16 injectors and 8 coil packs
• Sequential fuel injection
• Optional flex fuel integration
• Dual throttle body capability
• Built-in dual wideband controller for accurate air-fuel monitoring
• Real-time tuning with VCM Live software
• Data logging of up to 150 channels at 1 kHz
• Advanced boost, nitrous and launch control

• Motorsports-grade construction

Current engine support

• Gen III LS engines (drive-by-cable)
• Gen IV LS engines (drive-by-wire)
• More engine support is on the way

Harness options

Choose the ECU on its own or pair it with a harness above. Each harness is built for simple, durable connections to your sensors and triggers.

CORE GEN3 DBC Harness: for early (Gen III) LS engines with a cable-driven throttle.

• Drive-by-cable throttle body applications
• Cam sensor at the rear of the engine; knock sensors routed to the engine valley
• Dual Bosch LSU 4.9 wideband sensor connectors
• MAP sensor can be routed to the front or rear of the engine
• 20-pin input/output expansion connector for the sub-harnesses below
• EV6 injector connectors (EV6-to-EV1 adapters sold separately)
• Pre-terminated CAN connectors
• Can be paired with the optional GM transmission harness

CORE GEN4 DBW Harness: for late (Gen IV) LS engines with drive-by-wire.

• Drive-by-wire throttle body applications
• Cam sensor at the front of the engine; knock sensors on the side of the block
• Dual Bosch LSU 4.9 wideband sensor connectors
• MAP sensor can be routed to the front or rear of the engine
• 20-pin input/output expansion connector for the sub-harnesses below
• EV6 injector connectors (EV6-to-EV1 adapters sold separately)
• Pre-terminated CAN connectors
• Can be paired with the optional GM transmission harness

CORE 15' Flying Lead Harness: for builders who want a fully custom harness.

• Four AMP ECU connectors with cavity plugs
• Color-coded wiring in 15-foot lengths
• Instructions with connector diagrams, written for experienced users

Note: tech support is limited on flying-lead applications. It is the customer's responsibility to follow good wiring practice, and flying-lead harnesses are sold as-is.

CORE Transmission Control and I/O Harness: a single plug-and-play harness for GM 4L60E and 4L80E transmissions. No wiring changes or pin relocation needed.

CORE I/O Harness: a flying-lead harness for adding extra inputs and outputs, such as additional sensors, cooling fans and electric pumps.
