  1. That could explain why that's worked fine on my office desk. Thank you ;-)
  2. On my desk the firmware was updated successfully, I think I have to check the wiring on the car, maybe a power ground is missing... This is stange because when the car was arrived at the office the engine was running almost fine at idle... My first problem was to upload another map from the PC, on the car just after the upload, the power cycle is not done properly and I cannot store the new map on the memory. I will check the wiring !
  3. Thank you for your answer, unfortunately that doesn't work too. I think its a false positive error message. Just in case I tried to do the firmware update with the PClink G4 software, but same result... I will unmount the ECU form the car to do more tests on the desk. If you have another idea don't hesitate ;-) Thank you.
  4. I have a Vi-PEC V44 ECU and the whole mapping to do. First I have tried to upgrade the firmware to the lastest version (4.9.7 to 4.10.2) but there was an error during the upgrade process and now the ECU is still in boot mode but I cannot restart the upgrade process because of "Checksum_Failed" in file info. I already tried : - Change the PC (Windows 10 64bit -> Windows XP 32 bits) => no change. - Reduce the speed of the comm => no change. - Select other firmware => still the same error : Request firmware info failed with error "Checksum_Failed" Is there something to do to finish the upgrade process please ?
