LCU-ONE Analog User Manual Release 1.02 0 Chapter 1 – LCU-ONE Description LCU-ONE is a lambda controller unit for wide band BOSCH LSU 4.9 lambda probe; it fits petrol (2 and 4 strokes), diesel and methane engines as well as alcohol based fuel engines. It is intended to check lambda probe proper working as well as to transmit the Air/fuel ratio values providing MXL/EVO3 with lambda values through the CAN bus. Lambda value is defined as: LAMBDA= (A/F)/(A Stoichiometric /F Stoichiometric).
LCU-ONE Analog User Manual Release 1.02 1 Chapter 2 – LCU-ONE and Lambda probe mounting LCU-ONE controller should be installed in a flat location and far from heat sources; it should be mounted steady using the suited bracket. The wiring has to be arranged so to avoid it passing near to heat sources. LCU-ONE is to be powered by the engine master switch. BOSCH LSU 4.
LCU-ONE Analog User Manual Release 1.02 2 Chapter 3 – Configuration To work properly LCU-ONE Analog needs to be configured. The configuration can be made both using Race Studio 2 and using Lambda Configurator the free software included in the kit - properly designed and developed by AIM to configure this device. 5 3.1 – LCU-ONE Analog standard configuration Configuration through Race Studio 2 (standard) is possible only if calibration curve default points – 1.95=0.65 and 4.8=1.
LCU-ONE Analog User Manual Release 1.02 • Set the probe configuration panel that appears bottom left of channel layer, highlighted in the image below. • Activate the drop down menu pressing the arrow button circled in the image above and select the fuel used by the vehicle. www.aim-sportline.
LCU-ONE Analog User Manual Release 1.02 • In case the fuel used by the vehicle is not included in the database (and only in case its stoichiometric value is known) press the button “Add custom value” and the window here below appears. • Insert the new value and the test to match. Press “Add new item to the list” button and then “Save” button. The fuel is now available in the drop down menu: select it. • www.aim-sportline.
LCU-ONE Analog User Manual Release 1.02 8 3.2 – LCU-ONE Analog custom configuration In case calibration curve default points have been modified it is necessary to configure LCU-ONE Analog using Lambda Caonfigurator software. Warning: to correctly configure LCU-ONE Analog, please ensure you have installed a software version 1.00.07 or later. To configure LCU-ONE Analog run the software. The following window appears. This is software main window.
LCU-ONE Analog User Manual Release 1.02 11 3.2.1 – Preliminary operation Lambda Configurator software, unlike all other AIM software, contains LCU-ONE Analog firmware. This is why we recommend you to always check our website www.aim-sportline.com to ensure the software release installed is the latest available.
LCU-ONE Analog User Manual Release 1.02 At the centre of the window are configuration panels. The first operation to perform is selecting the used fuel in a pop up menu. In case used fuel is not included in the database and only in case its Stoichiometric value is known press “Add custom value” button and the window shown below appears. Fill in the window with Multiplier value and related legend. Press “Add new item to list value” and then “Save” button.
LCU-ONE Analog User Manual Release 1.02 Afterwards it is possible to work on the other parameters. “Use: Lambda/AFR” these buttons allow the user to decide whether showing Lambda values or AFR (Stoichiometric) ones. The appearance of the panel below depends on this choice; here down are the panels showing Lambda values (left) or AFR (right). The coloured button placed on the left of the cases indicates the colour of this value on the central graph. In the example the value is showed in light blue.
LCU-ONE Analog User Manual Release 1.02 12 3.2.3 – The keyboard On the left of the window are some buttons: • • • • “Restore default lambda settings”: allows the user to restore default settings on LCU-ONE Analog. “Transmit lambda configuration”: allows the user to transmit the configuration to the device “Read Lambda configuration”: reads the configuration from the connected device “UpgradeFirmware”: allows the user to upgrade the firmware of its device.
LCU-ONE Analog User Manual Release 1.02 13 3.2.5 – The analog output graph The “analog output graph” shows output tension values of the controller in correspondence of the measured Lambda values. Graph colours are customizable. Pressing “Colour options” button the window shown below appears: Pressing each button a colour panel will appear showing all the available colours for that characteristic of the graph. Selecting the desired colour and confirming the choice graph colours will change. www.
LCU-ONE Analog User Manual Release 1.02 3 Chapter 4 – Online values from Lambda controller. This panel shows controller status. The user is only allowed to set Lambda/AFR and temperature unit of measure for the values shown in this panel. www.aim-sportline.
