Greetings, I'm new to the board, but I have been monitoring things for a while.

I am in the process of converting a 2wd 1999 flex ranger that had a 3.0 v6 to a 1999 explorer 5.0 auto swap.
Reading the posted articles seem to be vary straight forward regarding the swap. I have the entire vehicle w/ pats and both ECMs.
My question is what will i have to do to get around the flex fuel sensor? I was just going to leave it alone, and hop for the best. I realize that the explorer ECM is a simple swap out for my ranger, but will it work with out setting a check engine code? I live in NW Indiana and we have obd2 emission testing.

Also will I have to use the explorer fuel tank sending unit, I figured this was a necessity because of the fuel regulator that is specific to the 1999 5.0 explorer.

I'm sure I will have o the questions about this swap, that will come in time.

Thanks in advance.

Dan.
 






don't connect it

The 1999 Explorer 5.0L PCM does not support the flex fuel sensor. Pin 34 is unused. Just don't try to connect the flex fuel sensor.
