Autotuner Failed to OBD Write PSA Delphi DCM7.1A Solution

Solution:

You have to hold and press key against the column the entire time if the writing yes.
Follow instructions exactly.

Hold the key in your hand throughout the writing process.
Always works with key held against column, it shows on autotuner instructions where to hold key.
Try holding key next to steering column as shown, and see if dash lights up
If lights come on you can rewrite the file with key again just make sure key is exactly where is should be as shown.

 How to read a Chevrolet SIM2K-D160 ecu with pcmtuner ? Use this in Module 30, 1,3,5 — ECU ground (just connect one of the contacts) 77 — CAN-High 78 — CAN-Low 76 — K-Line 2 — +12V (ignition on) 4 — +12V (power supply of the main relay) 6 — +12V (non-switchable power supply) You may not be able to do this ECU in BSL 53 as main processor is MPC756MXP56 Second Processor TC1738. You could try OBD Module 30 Kia/Hyundai SIM2K 2.0L, 2.5L (SIM2K-D160) But failing that, you would have to do this in BSL mode 53 http://www.pcmtuner.org/pcmtuner-module-53-infineon-tricore-bsl-operation/
