IP68 Compliant

CALIBRATION DATA

There are two distinct areas of calibration data memory, both with a separate password
protection access, one for vehicle or engine manufacturer like a main table, limits value,
sensors calibration data etc. Another one for the data in use to the Team, like the vehicle
control parameters, transmission/gear parameter, injection and ignition correction table ( with
limit fixed from engine manufacturer ), wheels parameters etc.
It is guaranteed the free access without a password, only for verification of diagnostic
parameters, for checking the firmware version, Hardware data ID, as well for reading the
GUID ( Globally Unique Identifier ) code of the calibration data. These GUID codes allow
unique identification and secure data on the ECU, enabling the staff of the manufacturer or
the FIA-FIM-DORNA scrutineer, the verification of compliance with applicable regulations
and approvals.

HISTORY BOOK

A read-only memory areas, is reserved to store events and conditions of danger for the
engine, eg. like a time overlimit rpm and max value, minimum oil pressure, water temp max
etc., operating time and a stress index of the engine. Additional recorded also events of
danger related to the vehicle, such as falls or impacts

BUNDLED SOFWARE

A free of charge MeCal ® Calibration software license it’s supplied with a single ecu. This
new tool is designed to make simple operations of setting the ECU to user without high skills,
allowing the manufacturer to customize the menu structure and the layout of the user
interface for example.

The sw tool for the acquisition data is provided from our partner 2D Datarecording ®.It’s a
specifical version of the notorius Analyzer2D® with Calctool and specview .

DASHBOARD

The Ecu works fully integrated with a specific version of the Big Dash, developed in
collaboration with the 2D Datarecording
