    Where does the flex link control module connect? Do we have a screenshot of the added tables for flex fuel? Is it just fuel multiplier? timing?

    The flex fuel sensor hijacks your choice of either the rear O2 sensor or one of the TGV sensors, which you select in the software. I don't have my MPVI2 on me right now so i can't open up a file, but it's not just just a fuel/timing multiplier. You are provided with blending tables and a 0% ethanol and 100% ethanol content tables for many fuel/cam/timing/boost related tables. Then based on the blending table, a new value for the actual output is calculated.
