Haltech Nexus R3 VCU.
The Haltech Nexus R3 VCU (Vehicle Control Unit) is an advanced, all-in-one control system designed for high-performance racing applications. This single, powerful device integrates a state-of-the-art engine management system, a power distribution module (PDM), a high-speed data logger, and a wideband controller. By combining these essential functions, the Nexus R3 simplifies vehicle electronics and wiring, eliminating the need for multiple external modules. It is engineered for engines with up to 8 cylinders or up to 4 rotors, making it the ultimate solution for drag racing, road racing, and custom engine setups.
Features and Software Functions:
- All-in-One Integration: Integrates ECU, PDM, wideband controller, and data logging in a single vehicle control unit.
- Integrated Power Management: Features four 25A high-current outputs to directly power critical components like fuel pumps, fans, injectors, and coils.
- Complete Tuning Capability: Controlled via NSP (Nexus Software Programmer) with up to 4D long-term learning and a 32x32x8 4D tuning table resolution.
- Advanced Race Controls: Includes traction control, launch control, trans brake control, race timer, anti-lag, and rotational idle.
- Advanced Engine Management: Features multi-level engine protection, dual knock control, and up to 4-sensor variable cam control.
- Comprehensive Boost and Fueling: Offers 4D closed-loop boost control, closed-loop CO2 control, up to 6 stages of nitrous control, and multi-stage fuel injection.
- Dual Drive-By-Wire: Fully supports dual electronic throttle bodies with built-in redundancy.
- Automatic Transmission Control: Built-in support for Ford AODE/4R70W, GM 4L60E, GM 4L80E, Toyota A340E, Lenco, and Liberty transmissions.
- High-Speed Logging: Onboard data logging of up to 300 channels at sample rates up to 1ms (1kHz) with 128MB of internal storage.
- Modern Connectivity: Built-in Wi-Fi, compatibility with the Haltech Connect App, and a USB-C port for low power up via cable and high-speed communications.
