I decided to update my efi software to version 6 on my 1966 Early Bronco. Originally my ECU started out as a terminator (HP) with version 2 software. Pretty easy process.
1. First backup your global configuration file.
2. Upgrade firmware
3. Restore global configuration file
4. Set your throttle position sensor

Upgrading the firmware completely erases everything on your ECU
