Haltech Elite 2500 Terminated Harness ECU Kit w/EV1 Injector Connectors

If you're looking to unlock the full potential of your engine with custom tuning, the Haltech Elite 2500 ECU Kit is a serious contender. This kit replaces your factory engine control unit (ECU) with a powerful, programmable unit that gives you granular control over fuel, ignition, and other critical engine functions. It's designed for builders and tuners who need a flexible and robust platform to achieve specific performance goals, whether that's maximizing horsepower, improving drivability, or fine-tuning for unique engine builds.

The Elite 2500 is a well-known name in the performance tuning world, and this terminated harness kit makes installation more straightforward. It comes with a pre-wired harness featuring EV1 injector connectors, which are common on many performance fuel injectors. This means less time spent crimping wires and more time focusing on the tune itself. The ECU itself boasts advanced features like dual processing power for faster calculations, extensive inputs and outputs for sensors and accessories, and the ability to manage complex engine configurations. You'll be able to map fuel and ignition timing with precision, control boost, manage water-methanol injection, and much more, all through Haltech's intuitive software.

When installing a standalone ECU like the Elite 2500, it's important to have a solid understanding of your vehicle's wiring and engine management system. While this kit simplifies the harness aspect, proper tuning requires expertise. You'll want to ensure you have the necessary tools and knowledge, or plan to work with a professional tuner to get the most out of this system. This kit is not CARB approved and cannot be shipped to California. It's a powerful tool for serious engine builds where custom calibration is key to performance.
