ETK/FETK/XETK

The Ethernet-based ETK, XETK, and FETK interfaces provide direct access to the control variables and parameters of an ECU via the parallel data and address bus, or via a serial microcontroller testing or debugging interface. The interface is real-time capable. Its dedicated power supply enables the preparation and initiation of cold-start testing independently of the ECU. Due to their extremely compact design, ETKs/XETKs/FETKs can be accommodated inside the housings of production ECUs. They are impervious to the temperature extremes and vibrations at the ECU's location in the vehicle.

In contrast to alternative methods which burden the ECU program with the task of both data access and data transfer through a serial interface, very little computing overhead on the part of the ECU is needed. On engine ECUs, for example, large numbers of measured values can be acquired easily without impact on ECU overhead, even in the presence of high engine speeds with their substantial burden on computing power.

Due to their construction, ETK/XETK/FETK development ECUs do not require an additional serial interface to connect to the development tool. As a functionally and physically separate addition to the ECU, they facilitate direct comparison between the behavior of the development ECU and its production counterpart. Series-production software can be calibrated with great ease and subsequently verified with the production ECU without the need to change drivers in the platform software.

The ETK Tools installation package allows existing INCA installations to be extended and updated to add ETK-, XETK-, and FETK-specific features and corrections. The ETK Tools version that is valid when an INCA release takes place is included on the INCA installation DVD.
