Haltech Nexus R5 ECU

VCU OVERVIEW

Nexus R5 is Haltech's flagship product, combining the functions of a power distribution module, data logger, dual-channel wideband controller, and state-of-the-art engine management system in one powerful device, which we call the VCU (Vehicle Control Unit).

• 4 x 25A (continuous) outputs capable of push-pull PWM (5 kHz) (for powering injectors/coils, transbrake, thermofan, fuel pump)
• 12 x 8A (continuous) high-side (low speed PWM, 200Hz) outputs (powering sensors, NOS solenoids, etc.)
• 18 x Peak/Hold injector drivers (can be used as low-side drive outputs)
• 12 x low current ignition outputs (can be used as low side drive outputs)
• 8 x low-side PWM-capable outputs (DPO)
• 4 x push-pull / h-bridge outputs (8A, PWM capable), e.g. for electronic throttle
• 23 x 0-5V analog inputs with electronic throttle override and switchable 5V pullup
• Trigger and start inputs with differential inputs, adjustable thresholds and fault filters
• 10 x synchronous pulse inputs, zero crossing or adjustable thresholds - cam sensor inputs, frequency inputs or analog inputs 0-5V
• 2 x integrated broadband controllers, supporting NTK and LSU4.9
• 3 x CAN ports with switchable termination
