Haltech Nexus R3 VCU

The Haltech Nexus R3 VCU (HT-193000) combines the functionality of a power distribution module, a data logger, a wideband controller and a state-of-the-art engine management system in one Vehicle Control Unit.

The R3 provides 4 x 25A continuous push-pull PWM capable (5 kHz) outputs for injectors, coils, transbrake, thermofan or fuel pump, 8 x peak/hold injector drivers usable as low side drive outputs, 8 x low current ignition outputs usable as low side drive outputs, 6 x low side drive outputs (PWM capable DPOs), and 6 x push-pull/h-bridge outputs (8A, PWM capable) for electronic throttle. It carries 11 x 0-5V analog inputs with redundancy for electronic throttle and switchable 5V pullup, trigger and home inputs with differential inputs, adjustable thresholds and glitch filters, and 6 x synchronous pulsed inputs for cam sensors, frequency inputs or 0-5V analog inputs with zero crossing or adjustable thresholds. It includes 1 onboard wideband controller supporting NTK and LSU 4.9 sensors, 1 onboard 4 bar MAP sensor, 2 CAN ports with switchable termination, and onboard data logging of up to 300 channels at sample rates up to 1ms (1kHz) with 128MB of internal memory.
