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.
The Nexus T1 ECU uses the new Nexus Software Programmer (NSP) that brings levels of functionality and user-friendliness in an engine control package.
Together they offer true cutting-edge technology to tuners and performance enthusiasts worldwide.

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 compensations and multiple user-definable corrections
· Tuning Table Resolution up to 32 x 32 x 8 (4D)
· Tune by a combination of manifold pressure, throttle position, cam position, ethanol content, gear, road speed, race time, EGT, shock travel, ride height or any channel for ultimate flexibility - Dual mapping is a thing of the past.
· Per Cylinder Tuning Correction - 3D
· Wideband O2 - Connect up to 3 Channels via CAN expansion devices
· Thermocouples / EGT (Exhaust Gas Temperature) - Connect up to 12 Channels via external CAN expansion devices
