On there, they state the AFR is linear and found by using the formula 2*V+9.6
Now, since the EIO needs Volts/XX + XX The formula you should start with should be:
Volts/.500 + 9.6
They also say the linear output is shared with the narrow band output, and mention having to change the option in software but I think that is just so their logging software works fine. Hopefully it always outputs a 0-5v signal, and not a narrow band 0-1v on that purple wire.
Once you get that squared away...I would find the offset by using this procedure: http://www.hptuners.com/forum/showthread.php?t=11018
