Haltech Nexus T2 ECU (HT-211000)
The Haltech Nexus T2 is a compact standalone engine management system designed for performance applications that require up to six channels of sequential fuel and ignition control.
As the successor to the Elite 750, the Nexus T2 features six peak-and-hold injector outputs and six ignition outputs. It is ideally suited to six-cylinder and three-rotor engines, while engines with up to 12 cylinders can also be controlled using semi-sequential or batch-fire configurations.
The T2 delivers a significant technology upgrade over the Elite platform. Wi-Fi tuning, Haltech Connect app compatibility, multi-level engine protection, knock control and advanced onboard logging are supported alongside motorsport functions including traction control, launch control, rolling anti-lag, trans-brake control and up to six stages of nitrous control.
An internal 4 Bar MAP sensor makes the ECU suitable for naturally aspirated and forced-induction engines. Five configurable analogue voltage inputs, five digital pulsed outputs and CAN communication provide flexibility for additional sensors, Haltech displays, wideband controllers and compatible expansion devices.
Haltech's Nexus Software Programmer provides access to high-resolution 4D tuning, long-term learning and advanced closed-loop boost control. High-speed USB-C, Wi-Fi connectivity, a four-channel oscilloscope and 32MB of onboard logging make configuration and fault-finding faster and easier.
The Nexus T2 shares its connector and pinout with the Elite 750, allowing compatible Elite 750 wiring kits and existing installations to be reused. Pin 13 can operate as either a knock input or SPI 2 input.

What engines is the Haltech Nexus T2 suitable for?
The Nexus T2 supports sequential fuel and ignition control for engines with up to six cylinders or three rotors. Engines with up to 12 cylinders can also be operated using semi-sequential or batch-fire configurations.
Does the Nexus T2 support drive-by-wire throttle?
No. The Nexus T2 is designed for cable-throttle applications and does not provide drive-by-wire throttle control.
Can the Nexus T2 replace a Haltech Elite 750?
The Nexus T2 uses the same connector and pinout as the Elite 750, so compatible Elite 750 wiring kits and many existing installations can be reused. The configuration and pin functions should still be checked before installation.
Does the Nexus T2 have a built-in wideband oxygen controller?
No. Wideband oxygen control requires a compatible external Haltech CAN wideband controller such as a WB1 or WB2, sold separately.
What is included with the Haltech Nexus T2 ECU?
The package includes the Nexus T2 ECU, a USB-C programming cable, USB-C dust cap and mounting bolt set. A suitable wiring harness or connector kit is required separately unless supplied as part of another kit.
