What is Torque Management?

The Torque Management function is designed for drag racing applications, managing engine torque in order to maintain optimal wheel speed, resulting in optimized grip, acceleration and ultimately race times. This function allows you to program a desired ‘’Driveshaft Target RPM’’ verses a range of different operating conditions. If the Driveshaft goes above the ‘’Driveshaft Target RPM’’user defined value, an extremely fast control system reduces engine torque by retarding the ignition timing and/or cutting individual cylinders until the Driveshaft RPM speed falls below the user defined value target. The amount of ignition retard, as well as when to use cylinder cut is determined from the user-configurable tables in the ESP software. Additional torque reduction can be achieved by reducing boost or delaying a stage of nitrous. It is important to note that Torque Management will never advance the ignition timing past your ignition base table. If there are pre-programmed timed ignition retards active and driveshaft speed falls below the target, the torque management can override these pre-programmed timed ignition retards.


What is a PDM (Power Distribution Module)?

A power distribution module is a device fitted with multiple outputs designed to distribute electric power.  This Nexus R5 pdm allows you to control the electrical power to the individual components that run your engine; ignition coils, injectors, boost solenoids, electric water pumps, ECU controlled relays, Fuel pumps, dash displays, gauges, Nitrous solenoids, trans brake, 12v sensors. 


What is a data logger?

A data logger is a device that monitors / stores information related to what attributes that are provided to the device. The Nexus R5 is the next generation of ECU which incorporates data logging into one unit with its 300 channel, 1kHz logging with 512MB of logging space surpassing / matching any ECU on the market to this date. This allows an individual to not only maximize the performance of the engine but allow an individual the ability to interpret the data from the multitude of customize-able sensors making the vehicle be faster on the race track. 

What is high speed wi-fi module?

This niche feature allows Haltech Nexus R5 customers the ability to easily access the Nexus R5 ECU seamlessly allowing an individual to make changes to the vehicles engine management system without connecting to the chassis. This is the go too option for quick changes after each pass on the track!
