Product Overview: Elite 2500

The future of engine management is here!

Haltech’s Elite 2500 ECU takes the art of engine calibration to a whole new level. Featuring a robust environmentally sealed waterproof 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 the tools they need to get the job done right.

Alongside the Elite 2500 ECU is the Elite Software Programmer (ESP) that brings with it 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.

This ECU is available as a stand-lone ECU only or in a kit with a choice of basic or premium, long or short universal engine harnesses.

The Elite 2500 is also available with a range of make/model specific Plug’n’Play Adaptors or with engine specific Terminated Engine Harnesses.

Elite 1500 vs Elite 2500

What’s the same:
• Waterproof case
• Drive-By-Wire
• Variable Cam Control
• Self Learning Fuel Maps
• Data Logging
• Anti-Lag and Launch Control
• Open and Closed Loop Boost Control
