Haltech Nexus R5 + LSx Non DBW Terminated Harness

Haltech Nexus R5 + LSx Non DBW Terminated Harness

The Haltech Nexus R5 is Haltech's flagship VCU (Vehicle Control Unit), combining the power and intelligence of a power distribution module, a high-performance data logger, dual-channel wideband controller, and a cutting-edge engine management system — all in one seamless unit. This Nexus R5 kit comes bundled with a terminated harness designed specifically for LSx engines without DBW (Drive-By-Wire), making it an excellent plug-and-play solution for serious engine management.

Nexus R5 Highlights

• 4 x 25A continuous push-pull PWM (5kHz) outputs – ideal for injectors, coils, transbrake, fan, and fuel pump
• 12 x 8A continuous high-side outputs with 200Hz PWM for sensors, NOS solenoids, etc.
• 18 x Peak/Hold Injector Drivers – can also function as low-side outputs
• 12 x Low Current Ignition Outputs – usable as low-side outputs
• 8 x Low Side Drive Outputs – PWM capable (DPOs)
• 4 x H-Bridge Outputs – 8A push-pull outputs, PWM capable (ideal for e-throttle control)
• 23 x 0-5V Analog Inputs – with redundancy and switchable 5V pullups for sensors
• Trigger/Home Inputs – differential with adjustable thresholds and glitch filters
• 10 x Synchronous Pulsed Inputs – for cam/frequency/analog input options
• 2 x Onboard Wideband Controllers – supports both NTK and LSU4.9 sensors
• 3 x CAN Ports – each with switchable termination
