Haltech Nexus T1 ECU - Standalone Engine Management for 4 Cylinder and 2 Rotor (HT-210000)

Haltech Nexus T1 ECU

Meet the Nexus T1, Haltech's entry-level, single connector standalone ECU and the official successor to the Elite 550. Built for basic street performance applications and EFI conversions, the Nexus T1 delivers full control over fuel delivery, ignition timing and boost on naturally aspirated or forced induction engines, all in a compact, environmentally sealed IP-66 waterproof case.

Whether you are wiring up a turbo 4 cylinder street build, a carb-to-EFI conversion or a 2 rotor project, the Nexus T1 brings modern Nexus platform technology at an entry-level price point, running the latest NSP (Nexus Software Programmer) calibration software with WiFi and USB-C connectivity.

Applications

• Universal fitment for 1 to 4 cylinder engines
• Up to 2 rotor rotary applications
• Naturally aspirated or forced induction
• Ideal for basic EFI conversions and street performance builds

Key Features

• 4 x ignition outputs supporting direct fire multi-coil, distributor or Haltech CDI systems
• Internal 4 Bar MAP sensor
• 2 x differential engine position inputs (trigger and home)
• 5 x analog voltage inputs and 5 x digital pulsed outputs
• 1 x knock input (shared with SPI 2) with single channel knock control
• Load sensing by TPS, MAP or MAF
• Sequential, semi-sequential, batch or multipoint injection patterns
• 2 injection stages for rotary engine applications
• Closed loop O2 control with long term learning (with optional external CAN wideband controller kit)
• 4D closed loop boost control with learning, flexible user-definable axis and 6 fully user-definable correction modes such as boost by gear or road speed
• Flex fuel with direct sensor input, tune boost, fuel and ignition by ethanol content
• Closed loop idle speed control (requires 1 or 2 user-defined BAC type outputs)
• Variable cam control for up to 2 camshafts (requires a minimum of 1 user-defined input and output per cam)
• Multi level engine protection
• Launch control, traction control, anti-lag, rolling anti-lag and advanced flat shift support
• Nitrous control with up to 6 stages, trans brake and race timer functions
• 32MB onboard logging plus laptop logging, up to 300 channels at up to 1kHz
• 4-channel onboard oscilloscope (50kSa/s per channel)
• CAN connectivity for Haltech dashes, keypads and expansion devices, plus OBDII to view live engine data and set and clear diagnostic trouble codes
• Compatible with the Haltech Connect app
• Tachometer output
• WiFi via internal antenna and high speed USB-C laptop communication
• IP-66 waterproof case, 34 position Superseal connector
• Fully enabled from the box with no extra feature unlock charges

Advanced Tuning

• Limitless tuning flexibility with 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; dual mapping is a thing of the past
• 3D per cylinder tuning corrections
• Long term learning up to 4D
• Wideband O2: connect up to 3 channels via CAN expansion devices
• Thermocouples / EGT: connect up to 12 channels via external CAN expansion devices
• Shock travel and ride height inputs supported
