Use this, and never look back:
Divisor: .7096
Adder: 9.102
This makes it report correctly for a stoich value of 14.68, which is what most PCMs use. Make sure you have a GOOD power and ground... (ie: straight off the battery), and just leave it be. You will beat yourself up nickel-and-diming the values to try and get them exact. Ignore the display box.
