    Ran into some P59s that have IAC driver but dont show flex timing addr when enable

    Enabled flex sensor on both of these, and scanner doesnt show flex timing adder available? I tend to use only one or two OS with these, am I missing something?

    No. P59 flex segment. Just flipping the switch doesn't work.
