Any solution?


AutoTuner Failed to Write VW DQ250F Gearbox Car Not Start
AutoTuner Failed to Write VW DQ250F Gearbox Car Not Start

Solution:

If fail write, never turn ignition off, try again write the modified file, if again fails, than is problem in modified file, and write original file.
Always hit write again straight after.
When you have such errors by writing a modified file, never turn off the ignition. With the ignition cycling it uses the newer corrupted flash to start and that was it.

The ECU is now bricked, and needs to recover it.

Flex with frf over OBD or dimsport recovery over OBD, Kess recovery or flash with Odis engenering and frf file!!

PCM flash is also very good at recovering in Bench mode.

PCMTuner Chevrolet SIM2K-D160 ECU Pinout

 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/
