Core ECU

Take complete control of your engine with HP Tuners’ first standalone ECU. CORE ECU delivers pro-level calibration flexibility, real-time tuning, and robust data logging—perfect for high-performance builds, swaps, and motorsports. At Squid’s Rod Shop, we’re an authorized HP Tuners dealer, and we run CORE ECU on some of our most advanced projects for its precision, reliability, and clean integration with modern LS platforms.

Why CORE ECU?

Supports up to 16 injectors and 8 coil packs, sequential fuel, boost/nitrous/launch control, and CAN integration.

HP Tuners Tune live, log fast: Works with HP Tuners’ new VCM Live for real-time adjustments and up to 150 channels of 1 kHz data logging—ideal for dialing in drivability and peak power.

LS ready: Current support for Gen 3 (DBC) and Gen 4 (DBW) LS engines, including both 24x and 58x crank triggers—exactly what most swap and performance customers need.

HP Tuners Harness Options:

• Terminated Gen 3 Drive-By-Cable LS main harness
• Terminated Gen 4 Drive-By-Wire LS main harness
• Flying-lead (custom) harness kit
