Haltech HT-150402 Features:

The Elite 550 is a versatile and cost-effective ECU, ideal for 4–8 cylinder or 1–2 rotor engine builds. Compatible with both naturally aspirated and forced induction systems, it provides precise control over fuel delivery, ignition timing, and boost levels.

Ideal for dedicated race cars, engine swaps, and custom wiring jobs. The Universal Wire-in Harness has a set of ECU connectors at one end and unterminated wires at the other. All the wires at the unterminated end are colour coded and clearly labelled. Connect your Haltech ECU to the terminated end and follow your wiring diagram for all the engine connections. Load your base map and you're ready to go!
