Hello, I use version 111 for trigger Audi, I installed the USB support to save the data, on the computer it displays as if the USB saves OK, I have the file saved on the key but I can’t read it, it displays crashed and the program quits. I think it’s a software problem? Thanks for your help

Thanks for your reply, it’s a SanDisk 32G key, I can’t read the LOGs at all, if the LOGs are OK then the system is good, it must be another problem, plus I read the ADU LOGs and it works. Thank you and best regards.

Hello mKuklis, I tried the log with the USB key with version 115.2, there is no more Crash but it still can not open the Log. I think there is still a problem with the software. Thanks for your help. Best Regards Yann [Log] [log1] Audi Quattro 115.emupro (30.9 KB) 20241105_2048_30.emuprolog …

Thank you for your reply, I have a good quality Sandik USB key that I use to save ADU data. I can’t open any files. I’ve tried another key but from the same brand. The cable is shielded and installed according to your diagram. With the new software, there are no more crashes like before, or eve…

I don’t see anything wrong there. This points me to the reading process from the flash after saving. How exactly do you recover the log from the USB drive? Do you disconnect it from the ECU and connect to the PC? Or do you use the tool inside the EMU software? If you disconnect the drive, do yo…

Hello, thank you for your reply. I retrieve the USB key directly from the bracket and put it on the PC. Then I retrieve the file as if I were retrieving a LOG saved on the PC. I switch off the ignition and remove the key from the bracket. I supply the box with continuous 30 and 15 to cut key cont…

Or do I have a LOG de faut parameter in the selection? But before the last update there really was a crash and now it says file corrupted.

Hello mKuklis, for information, I have wired again USB and a new support USB, same problem. I think there really is a problem with the software or the ECU? Thank you for your help. Best Regards Yann
