LCU-ONE CAN connected to MyChron4 User Manual Release 1.04 0 Chapter 1 – LCU-ONE 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 MyChron4 with lambda values through the CAN bus.
LCU-ONE CAN connected to MyChron4 User Manual Release 1.04 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 heart sources. BOSCH LSU 4.9 Lambda probe should be installed on the vehicle exhaust pipe using a specific adaptor that comes with the kit and should be weld on the same pipe.
LCU-ONE CAN connected to MyChron4 User Manual Release 1.04 We would suggest to install Lambda controller and the related probe as shown in the following figures. It is suggested to place LCU-ONE highlighted below under the kart number plate: Let the power cable (2) and the probe cable (1) pass around the steering wheel castle. www.aim-sportline.
LCU-ONE CAN connected to MyChron4 User Manual Release 1.04 Probe cable should be fixed to the driver seat as in the figure below: The probe should be inserted in the most suitable location of the exhaust pipe. We would suggest to install it in the exhaust pipe flexible tube (see figures below): Lambda Probe www.aim-sportline.
LCU-ONE CAN connected to MyChron4 User Manual Release 1.04 2 Chapter 3 – Connection with MyChron4 + ─ Connecting Lambda controller to MyChron4, the system automatically switches on and recognises the peripheral at start up. Warning: connect LCU-ONE CAN to MyChron4 OFF. In the figure above, LCU-ONE CAN controller is connected to MyChron4 through Data Hub, the CAN connections multiplier.
LCU-ONE CAN connected to MyChron4 User Manual Release 1.04 3 Chapter 4 – Configuration on MyChron4 The only configuration needed to better use MyChron4 is choosing the temperature channel shown together with LAMBDA value. Press Menu button selecting Configuration icon: Afterwards select temperatures setup icon: This window appears: Using left buttons (“UP”/”DOWN”) select “Temp with Lambda” row. Pressing “ENTER” the desired input is set.
LCU-ONE CAN connected to MyChron4 User Manual Release 1.04 4 Chapter 5 – Visualisation on MyChron4 Switching MyChron4 on Lambda controller is recognised at start up and probe WarmUp procedure starts. During this period the controller takes the probe to its working temperature (until around 780 °C – 1436 °F). During warmup (around 20-30 seconds), displayed lambda value is 1.00. When the probe is 100% working, displayed value turns, with the engine off, into 1.60 (free air value).
