A customer failed to read Opel Siemens SIMTEC71.6 ECU with foxflash programmer, software gave an error silent key.
Foxflash engineer solution:
Regular bench mode may fail to read this ECU.
You need a breakout box converter, i.e Godiag GT105 to read it via obd on bench (in car).
Here is the pinout to SIEMENS SIMTEC71.6
