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 !
