Description

The Nexus T1 ECU is a Haltech engine management ECU engineered to give you full control over fuel, ignition and auxiliary functions for serious performance builds.

The Nexus T1 is designed as the successor to the Elite 550, catering to basic street‑performance applications. It supports up to four cylinders using direct‑fire ignition and sequential injection, or up to two rotors with direct‑fire leading/trailing ignition and two‑stage sequential injection.

Ecu Overview

The Nexus T1 is a compact, stand-alone ECU designed as the successor to the Elite 550, built for basic street-performance applications. Suitable for either naturally aspirated or forced induction engines, the Nexus T1 gives you full control over fuel delivery, ignition timing and boost levels. This robust, competitively priced ECU features an environmentally sealed, waterproof case, 4 fuel and 4 ignition channels, and an onboard 4 Bar MAP sensor. Together they offer true cutting-edge technology to tuners and performance enthusiasts worldwide.

Outputs: Up to 4 injector and 4 ignition.

Key Features:

ECU FUNCTIONS
· O2 Control – Closed Loop with Long Term Learning – for precise tuning (With optional external CAN O2 Wideband Controller Kit)
· Boost Control – Closed loop with learning with flexible user-definable axis and 6 fully user-definable corrections modes – for example, boost by gear, road speed etc.
· Flex Fuel Function (Direct sensor input) – Tune your engine’s boost, fuel and ignition by ethanol content
· Low Impedance Injector control with Programmable Injector Peak and Hold Currents
· Closed Loop Idle Speed Control – requires 1 or 2 user-defined outputs (BAC type)
· On-board and Laptop data logging – Data log all available channels directly to your laptop’s hard drive for both tuning and diagnostics
· CAN Bus communication for Haltech Dashes and expansion devices or OBDII (view live engine data and set and clear diagnostic trouble codes)
· 2 Injection Stages for use with Rotary Engines
· ECU comes fully enabled, with no additional charges for advanced features.
· Variable cam control – Independently control up to 2 camshafts – Requires a minimum of 1 user-defined input and output per variable cam
ADVANCED TUNING
· Limitless tuning flexibility – Tune your engine by a combination of 4D tuning tables combined with 3D per cylinder compe(more…)
