DESCRIPTION

The MLE-340 Engine and Vehicle Control Unit is a powerful and complete concentrated system capable of controlling high performance engines up to 4 cylinders. Suitable for motorbike applications. It incorporates a powerful data acquisition unit tailored to racing applications which require high resolution data, high bandwidth and a large number of channels. The unit can drive ON-OFF injectors, inductive
ignition coils and a large number of additional loads. The communications capability is assured by 4 CAN lines, 1 100 Mb/s Ethernet line for fast data download and data transfer to other units. The logic architecture consists of a powerful dual-core processor for data logging, telemetry and communications, while calculation, control and actuation are managed by a high performance microcontroller for a total computation power of over 2,500 Dhrystone MIPS. The MLE-340 is equipped with a variety of analogue inputs including single-ended, temperatures and differential together with digital inputs for lap trigger,
VRS/Hall and Hall/Rate inputs.
