I did change the upload timeout to 15 seconds before i tried updating the firmware.
Got out and drove it a bit. It's 32 degrees here so i never mashed it off the line, but i could definitely tell a difference. Looking forward to the day we have nice weather again and the car has fully adapted to the tune!
EDIT: something went haywire and the engine kept dying, (got a cel and warning that engine was at half power, but it wouldn't even stay running). Of course this happened in front of the wife (she was already against the tune). Uninstalled for now and will attempt again this weekend, so disappointed.
No F30 firmware has been posted. So you probably screwed something up with the laptop if you tried to upload something? Email BMS if you need assistance.
