The Nexus T1 is Haltech's entry-level stand-alone ECU and the direct successor to the Elite 550. It is built for street-performance builds and basic EFI conversions on 1-4 cylinder or 2 rotor engines, naturally aspirated or forced induction, giving you full control over fuel delivery, ignition timing and boost.Everything runs through a single 34-position Superseal connector in an environmentally sealed IP-66 waterproof case, so it is happy mounted in the engine bay. An internal 4 Bar MAP sensor is built in, and the ECU comes fully enabled - there are no locked features or extra charges to unlock them.Outputs and inputs 4 x fuel injection outputs (peak and hold, 8A peak / 2A hold) 4 x ignition outputs 5 x digital pulsed outputs (DPO) 5 x analog voltage inputs (AVI) 2 x differential engine position inputs (trigger and home) 1 x synchronised pulsed input, plus 1 knock input (usable as SPI 2) Internal 4 Bar MAP sensor Tuning and logging Nexus Software Programmer (NSP) calibration software 32MB onboard logging, plus laptop logging 4-channel onboard oscilloscope (50kSa/s per channel) Closed loop O2 control with long term learning (requires optional CAN wideband controller kit) Closed loop boost control with learning, tune by gear or road speed Flex fuel, launch control, traction control, anti-lag, trans brake and multi-level engine protection Variable cam control for up to 2 camshafts 4D tuning tables up to 32 x 32 x 8 with 3D per-cylinder correction Connectivity Wi-Fi via internal antenna, works with the Haltech Connect app USB-C laptop communication (Windows) CAN bus for Haltech dashes, expansion devices and OBDII Specifications Enclosure: 111 x 131 x 40 mm, not including connector protrusion Power supply: 8 to 22V Operating temperature: -40 to 125°C ambient Weight: 0.39 kg What's in the box Nexus T1 ECU USB-C cable and USB-C dust cap Mounting bolt set Haltech fabric keytag Quick start guide and universal wiring diagram A wire-in harness is not included.
