    Not familiar with the brand but what are you looking for exactly? Do you need to know what formula for hptuners or what?

    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
