Haltech Elite 750 ECU + Basic Universal Wire-in Harness Kit (HT‑150602)

The Elite 750 is an entry-level standalone ECU that brings many of the tuning and data logging capabilities of the Elite 1500/2500 series at a more accessible price point. Featuring a waterproof case (IP67), 6 injector and 6 ignition channels, and onboard data logging with flex‑fuel tuning, it’s a compact powerhouse for custom engine builds and racecar applications.

Key Highlights

• NOT CARB LEGAL

• Engine Compatibility:

  • Supports 1–12 cylinder petrol engines or 1–3 rotor applications

  • Ideal for basic EFI conversions and VVT systems (e.g. Toyota 1JZ/2JZ, Mazda Miata NB, Duratec VVT)

• Robust Build:

  • IP67-rated sealed housing

  • Single 34-pin AMP connector

  • Onboard 3 bar MAP sensor capable of up to 2 bar (≈29 psi) boost detection

• Included Harness & Accessories:

  • Colour-coded universal wire‑in harness with labelled wires for straightforward wiring

  • Waterproof USB cap and Windows USB programming cable

  • Quick Start Guide, wiring diagram, among full ECU manual and NSP software on USB key or CD

⚠️ Note: This basic harness kit does not include a fuse or relay box.

ECU Functionality
