Measure All with High Performance ECU Access
Advantage of High Performance ECU Access
Added Value User‘s Advantage
MeasurementPerformance(2 byte signals)
Measurement efficiency A wide variety of measurement tasks can be combined into one (both on the bench and in the test vehicle).
Internal discussions on “signals to be measured” become obsolete.The validation of several functions take place simultaneously.
Recording of all ECU signals allow to analyze complex errors Measurement tasks can be fully documented at once
Ext. Bypass-Performance(roundtrip 128 bytes)
ECUs utilized with FETK can be used in Measurement & Calibration and Rapid Prototyping applicationsIncreasing of "ECU-Roundtrip requirements " allow to prototype more complex ECU functions with external bypass in real time prototyping of multiple ECU functions simultaneously
ECU – Flash programming
Unproductive waiting times can be reduced
ECU runtimeinfluence
No significant ECU runtime influence with FETK-T Runtime behavior of ECU functions (development ECU compared to mass production ECU) is identical. Thus error-
behavior can be analyzed in powerful development environment. ECU resources can be fully utilized for vehicle functions.
Test bench methods
Take advantage of test benches more efficiently due to the use of ETK / XETK / FETK at test benches time savings from 20% - 60% are possible (depending on applied calibration methods) increasing of engine’s service life achievable and quality improvements of calibration itself is possible
Min. ECU Raster Data acquisition of faster ECU processes possible (e.g. control function of electric machines, ...)

FETK-T are compact and powerful ECU access devices
Overview FETK & ES8xx
FETK-T
by utilizing the microcontroller TRACE interface (Aurora) for data
acquisition, which cause insignificant influence to microcontroller
runtime (raw data up to 300 Mbyte/s to be reduced and stored
in mirror RAM)
by capturing all ECU measurement labels, data throughput of
30 Mbytes/s and more is possible (ECU software dependent)
for external bypass applications, lowest roundtrip time of 100
µ sec and faster (for e.g. block of 128 byte) which ensures real
time prototyping with lowest latency
by measuring fastest ECU events, down to 5 µ sec
and minimized ECU flash programming time of 8 sec/Mbyte

Big Data (Storage) enables Data Mining (Access and Analysis). Explore huge amounts of data from various systems and domains to derive models / patterns /
results. We speak of a transformation of data into information / knowledge
A huge amount of measurement data is created during vehicle development. These data is usually used ones and thrown away
