HARNESS OVERVIEW
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!
Colour coded and labelled wires that match the detailed wiring diagram for a confusion free construction process.
The wiring diagram is accompanied by the full ECU manual and Software located on the CD or USB key provided with the ECU to refer to while completing your installation and configuration.
ECU OVERVIEW
Elite 2500 is a two-connector, stand-alone ECU ideal for popular late model performance and racing applications. Recommended for 4, 6, 8 cylinder, Drive-By-Wire (DBW) or 2, 3, 4 rotor engines, EFI conversions, engines with multiple variable camshafts. Featuring a robust environmentally sealed water-resistant IP67-rated case, drive-by-wire throttle control, intake and exhaust cam control, short-term and long-term map learning, dual channel knock control, and much more, the Elite 2500 ECU provides engine calibrators with the tools they need to get the job done right. The Elite 2500 ECU is now paired with the new Nexus Software Programmer (NSP) that brings levels of functionality and user-friendliness never seen before in an engine control package. Together they offer true cutting-edge technology to tuners and performance enthusiasts worldwide.
