Purchase a Pro Tuning License, then you can overlap cax defined cals and EFILive cals. When applying for a Pro Tuning License you must sign a waiver that indemnifies EFILive against claims that a controller was damaged or bricked by the EFILive software. That is because once the Pro Tuning License is installed, you can choose to bypass some critical checks that the EFILive software would normally perform to prevent the controller being bricked.
