:sly: I have a 2002 MXZ 500 L/C . What is that black rectangle box on top of my injection oil bottle?? Is that the DPM?? How do I know If I have DPM?? Probably a dumb question..Just bought the sled

my 00 700 had a sticker on the hood stating DPM, but you also ave a mpem box that controls the computer, so it should say what it is.

It is your MPEM module. If it was the original, it should have a sticker that says MPEM on it. If it is a replacement (like mine just got) it probably doesn't have the sticker on it.
