Haltech Nexus R5 VCU + Plug and Pin Set - HT-195100

The Nexus R5 VCU bundled with the connectors and pins to build your own loom. The plug and pin set lets you convert an existing loom or make a custom one to suit the Nexus R5.

The Haltech Nexus R5 is Haltech's flagship Vehicle Control Unit (VCU). It rolls four systems into one compact box: a full engine management system, a power distribution module (PDM), a high-speed data logger and a dual-channel wideband controller. Fewer separate modules means a simpler, lighter loom, fewer failure points, and one piece of software (Nexus Software Programmer, NSP) to set up the whole car.

Hardware highlights

• Runs up to 18 injectors (peak and hold) and 12 ignition outputs, so it suits engines up to 12 cylinders or 6 rotors
• Built-in PDM: 4 x 25 A push-pull outputs (PWM up to 5 kHz) and 12 x 8 A high-side outputs to power pumps, fans, coils, injectors, sensors and solenoids directly
• 4 x 8 A half-bridge outputs for drive-by-wire throttle and other H-bridge loads
• 8 PWM-capable low-side outputs, and spare injector/ignition channels can also be used as low-side drives
• 23 x 0-5 V analog inputs with switchable pull-ups and redundancy for electronic throttle
• 10 synchronised pulsed inputs for cam, speed and frequency sensors
• Differential trigger and home inputs with adjustable thresholds and glitch filtering
• Two onboard wideband controllers supporting NTK and Bosch LSU 4.9 sensors
• 3 CAN buses with switchable termination
• 512 MB onboard logging: up to 300 channels at up to 1 kHz
• Onboard Wi-Fi, USB-C connection and built-in G-sensor, compatible with the Haltech Connect app

Tuning and race features

• Long-term fuel learning (up to 4D) and dual closed-loop O2 control
• 4D closed-loop boost control and closed-loop CO2 boost control
• Launch control, traction control and advanced torque management (driveshaft and engine RPM targeting)
• Anti-lag, rolling anti-lag and rotational idle
• Dual knock control and multi-level engine protection
• Flat shift, transbrake control and race timer
• Up to 6-stage nitrous control
• Variable cam control for up to 4 cams
• Flex fuel, multi-stage injection, intake air bleed and stepper motor idle control
• Shock travel and ride height logging
• Automatic transmission control for Ford AODE/4R70W, GM 4L60E and 4L80E, Toyota A340E, Lenco and Liberty
