So,

When I did my swap, I printed out the guide to get the MPG gauge working (yes, I know it's worthless -- just bear with me here), and to my surprise, Pin 24 was already filled and had continuity with X16 up by the cluster. "Cool", I thought, one less thing to do.

But after finishing, I realized something was amiss -- at stoplights and such, the gauge shows 0mpg (correctly) but as soon as I start moving, it just swings right past 40mpg (burying the needle) and stays there. Obviously, it's getting more/less voltage than it should be... anyone ever experience this? I just left it alone for the last year, as I had a bunch of other stuff to sort out, but it's really starting to bug me, and I'm not exactly where to turn next...

Oh yeah, anyone know if it's possible to get the OBC to read this stuff correctly? Maybe a 323Ti OBC swap?
