Well now I am back to square one. Tactrix sent my ecu back and said they couldn't fix it. They said the bootloader was not responding. Not sure why they couldn't fix it because it was doing the same thing the first time and Cobb fixed it. I'm so frustrated at this point. I'm out another 50 bucks in shipping costs and it's been months with my car just sitting gathering dust. My tuner won't respond so I gave up looking for help there. After dropping over 7k in a motor build this year it's really aggravating. So do I try and send my ecu back to Cobb again or do I say screw it and find another ecu. Any suggestions?
