XMS-L - XTREME MANAGEMENT SYSTEM - LIGHT



The XMS-L (Xtreme Management System - Light) is a more affordable stand-alone system under the XMS product range. The XMS-L unit is ideal for applications that do not require all the functions and features of the XMS. The XMS-L has been designed to work on 4 cylinder engines only. The XMS-L has 2 ignition outputs with on-board drivers ideal for wasted spark applications, and 2 direct injector drives that allow for precise injector tuning. The XMS-L also has a 2.5bar on-board MAP (MAF) sensor.

The Windows Tuning Software is identical to the XMS, however only the features and functions that the XMS-L supports, will work. The software is user friendly and includes on-line help on all functions. The software also records the max. RPM, max Boost, max. Engine Temperature and max. Air Temperature. The XMS-L allows for live tuning, which means that changes can be made in real time or as you drive. The XMS-L can be connected to all standard factory sensors, such as Air Temperature, Engine Temperature, TPS (Throttle Positioning Sensor), etc.

The XMS-L Tuning software has two maps, which can be switched while driving. For example, Map A for economy or cruising and Map B for power or racing. The Tuning software also allows for the graphical display of all inputs in graphs or dial gauges.

The XMS-L uses a narrow band lambda input sensor for closed, open or partially closed loop operations. It also simultaneously monitors the engine temperature, air temperature, RPM and manifold pressure. The XMS-L Lambda circuit is used to reduce harmful vehicle emissions by ensuring that the engine is burning the fuel efficiently and cleanly (complete combustion).

The XMS-L uses multi-tooth crank signals for more precise ignition control of up to 10,000RPM at 60 teeth per turn or another corresponding trigger pattern that is compliant with the XMS-L.
