Mspnp2 and gm flex fuel snesor
Not sure if posting in the right section but i have been searching for a while and cant seem to find a clear way to wire a GM flex fuel sensor on my mspnp2. Do i have to run a wire from the ms to the sensor and what pin is it ?

There's whole section for megasquirt questions, you can use just about any analog input. Open up tuner studio and go to the flex fuel stuff, there is a drop down menu for inputs........ Any of the options in that list will work, just pick an open channel and wire it up. I hear there input labeled "flex" is popular.

You do, as well as a pull up resistor. The pin depends on the MS version. Forums will help with the pull-up (search). DIY's instructions are clear as far as which pin to connect.

Better
but more is needed grasshopper. Read every thread, even the ones that aren't PNP specific.
you don't need to crack the box, the pin is exposed in the DB connector
