Construction & Design:
The Elite 2500 ECU is housed in a rugged, environmentally sealed enclosure rated IP67, ensuring water resistance and durability in demanding conditions. The two-connector design uses AMP 26 and 34 pin 4-row 3-key Superseal sets, providing secure and reliable connections. This robust construction protects the ECU from moisture, dust, and vibration, making it suitable for both street and race environments.
The compact form factor and high-quality connectors simplify installation and integration into a wide variety of engine bays and wiring harnesses. The inclusion of a pocket cover further safeguards the unit’s connectors when not in use.
Installation & Fitment:
The Haltech Elite 2500 ECU is designed to fit most performance and racing applications across a broad range of vehicles and engine types. It supports engines from single-cylinder setups up to 12 cylinders, as well as rotary engines with up to 4 rotors. This flexibility makes it suitable for many popular late model vehicles and custom EFI conversions.
Installation requires integration with your vehicle’s wiring harness using the supplied plug and pin sets. The ECU supports a wide variety of sensors and ignition systems, allowing it to replace factory ECUs or serve as a standalone controller in custom builds. Tuning and calibration are performed via USB connection using the included Nexus Software Programmer (NSP).
