Haltech NEXUS T2 Standalone ECU – ECU Only | Universal | HT-211000

The Haltech NEXUS T2 is the mid-tier entry in Haltech’s NEXUS standalone ECU platform — stepping up from the T1 with an expanded I/O channel count for more complex engine builds that require additional sensor inputs, auxiliary outputs, or advanced control functions. Universal fitment — compatible with any engine when paired with the appropriate wiring harness. This listing is for the ECU only — a wiring harness (PnP adapter or custom build) and professional ECU tune are required and sold separately.

NEXUS T2 — Where It Fits in the Haltech Lineup

The NEXUS T2 sits between the T1 ($1,309) and the S3 in the NEXUS platform lineup. All three share the same NEXUS platform architecture and ESP tuning software — the differences are in I/O channel count and advanced feature availability. The T2’s expanded I/O over the T1 makes it the right choice for builds that have outgrown the T1’s channel count — engines with additional cam or crank sensors, more injector channels, additional auxiliary outputs for boost control solenoids, nitrous, water/methanol injection, or other ancillary systems. If the T1’s I/O is sufficient for your build, the T1 provides the same core engine management capability at a lower price. If your build requires the maximum I/O and advanced features, consider the NEXUS S3.

Key Features

• Expanded I/O Over NEXUS T1: More input and output channels than the T1 — accommodating more complex engine builds with additional sensors, injector channels, ignition outputs, and auxiliary control requirements. The correct choice when the T1’s channel count is insufficient for your build
• Full Standalone Engine Management: Complete programmable fuel and ignition control — supports sequential fuel injection, direct spark ignition, and a wide range of engine configurations. Full control over fuel maps, ignition timing, boost control, idle control, and all engine management functions
• Onboard Wideband O2 Control: Integrated wideband oxygen sensor controller — connect a wideband O2 sensor directly to the NEXUS T2 for closed-loop fuelling and accurate AFR data logging without a separate standalone wideband controller
• CAN Bus Connectivity: CAN bus support for Haltech’s range of CAN-compatible accessories and third-party CAN devices — dash displays, expander modules, and more. Clean, expandable system architecture without additional analogue wiring
• Haltech ESP Software: Configured and tuned using Haltech’s ESP (Elite Software Platform) — the same software used across Haltech’s full ECU range. Tuners familiar with other Haltech products will be immediately comfortable with the T2
• Universal Fitment: Compatible with any engine when paired with the appropriate wiring harness — either a Haltech plug-n-play adapter harness (available separately for supported vehicles) or a custom harness build
• Haltech Quality and Support: Manufactured by Haltech — one of the most respected standalone ECU manufacturers in the performance and motorsport industry, with an active global network of authorised dealers and tuners

What Else You Need

The NEXUS T2 ECU requires the following to complete a functional installation — none of these are included with this listing:

• Wiring Harness: Either a Haltech plug-n-play adapter harness (available separately for supported vehicles) or a custom harness build. The ECU cannot be installed without a harness
• Wideband O2 Sensor: A wideband oxygen sensor compatible with the NEXUS T2’s onboard controller
• Professional ECU Tune: A custom base map and dyno tune by a tuner experienced with Haltech systems and your specific engine. Do not attempt to run a standalone ECU without proper tuning — an incorrectly tuned ECU can cause engine damage
• Haltech ESP Software: Available from Haltech — required for configuration and tuning

Important: This listing is for the NEXUS T2 ECU only. Wiring harness, wideband O2 sensor, and professional tune are required and sold separately. Do not attempt to run a standalone ECU without a proper tune from a qualified Haltech tuner — an incorrectly configured ECU can cause serious engine damage.
