I've been trying to track down some solid answers on this too. I know you can, but I'd like to know table locations, especially for the 9653xxxx based roms.

Yeah, that's exactly what I search for - table locations. For now - I just installed switch which I use to turn on fan, when I want. But controlling fan via ecu would be great thing.

What ROM are you using? I spend the last hour or so searching on here and found the 96530006 based maps.

PHP Code:
    <table name="Thermo Fan Duty 0-22kph" category="Fan Control" address="575c" type="3D" level="2" swapxy="true" scaling="Percent (128)">
        <table name="Conditions" type="Static X Axis" elements="3">
            <data>Main Fan 0-22kph</data>
            <data>A/C Fan 0-22kph</data>
            <data>Main+A/C 0-22kph</data>
        </table>
        <table name="Engine Temp" address="6a14" type="Y Axis" elements="12" scaling="Temp"/>
    </table>

    <table name="Thermo Fan Duty 22-52-82kph" category="Fan Control" address="45ac" type="3D" level="2" swapxy="true" scaling="Percent (128)">
        <table name="Conditions" type="Static X Axis" elements="9">
            <data>Main Fan 20-50kph</data>
            <data>Main Fan 50-80kph</data>
            <data>Main Fan 80->>kph</data>
            <data>A/C Fan 20-50kph</data>
            <data>A/C Fan 50-80kph</data>
            <data>A/C Fan 80->>kph</data>
            <data>Main+A/C 20-50kph</data>
            <data>Main+A/C 50-80kph</data>
            <data>Main+A/C 80->>kph</data>
        </table>
        <table name="Engine Temp" address="6a14" type="Y Axis" elements="12" scaling="Temp"/>
    </table> 
And now w/ headers for those of us still using imperial units...

PHP Code:
    <table name="Thermo Fan Duty 0-12mph" category="Fan Control" address="575c" type="3D" level="2" swapxy="true" scaling="Percent (128)">
        <table name="Conditions" type="Static X Axis" elements="3">
            <data>Main Fan 0-12mph</data>
            <data>A/C Fan 0-12mph</data>
            <data>Main+A/C 0-12mph</data>
        </table>
        <table name="Engine Temp" address="6a14" type="Y Axis" elements="12" scaling="Temp"/>
    </table>

    <table name="Thermo Fan Duty >12mph" category="Fan Control" address="45ac" type="3D" level="2" swapxy="true" scaling="Percent (128)">
        <table name="Conditions" type="Static X Axis" elements="9">
            <data>Main Fan 12-31mph</data>
            <data>Main Fan 31-50mph</data>
            <data>Main Fan 50->>mph</data>
            <data>A/C Fan 12-31mph</data>
            <data>A/C Fan 31-50mph</data>
            <data>A/C Fan 50->>mph</data>
            <data>Main+A/C 12-31mph</data>
            <data>Main+A/C 31-50mph</data>
            <data>Main+A/C 50->>mph</data>
        </table>
        <table name="Engine Temp" address="6a14" type="Y Axis" elements="12" scaling="Temp"/>
    </table> 
Which gets you a table like this:

Something like this then.

PHP Code:
    <table name="Thermo Fan Duty 0-12mph" category="Miscellaneous" address="5186" type="3D" level="2" swapxy="true" scaling="Percent (128)">
        <table name="Conditions" type="Static X Axis" elements="3">
            <data>Main Fan 0-12mph</data>
            <data>A/C Fan 0-12mph</data>
            <data>Main+A/C 0-12mph</data>
        </table>
        <table name="Engine Temp" address="7034" type="Y Axis" elements="12" scaling="Temp"/>
    </table>

    <table name="Thermo Fan Duty >12mph" category="Miscellaneous" address="4012" type="3D" level="2" swapxy="true" scaling="Percent (128)">
        <table name="Conditions" type="Static X Axis" elements="9">
            <data>Main Fan 12-31mph</data>
            <data>Main Fan 31-50mph</data>
            <data>Main Fan 50->>mph</data>
            <data>A/C Fan 12-31mph</data>
            <data>A/C Fan 31-50mph</data>
            <data>A/C Fan 50->>mph</data>
            <data>Main+A/C 12-31mph</data>
            <data>Main+A/C 31-50mph</data>
            <data>Main+A/C 50->>mph</data>
        </table>
        <table name="Engine Temp" address="7034" type="Y Axis" elements="12" scaling="Temp"/>
    </table>
