It is not stand alone if you still have the PCM connected. The whole concept of stand-alone is to get rid of the PCM and control everything..I know the MS controls 90% of it and might take over the whole thing in the future but as of now it is not..I'm sure Slick will figure it out though..Makes me wish I would of taken more electronics classes in college.

look here no more PCM!
