I was just wondering if mpem and dpm are the same i heard people talk about dpm .My sled does not say dpm under the hood but does say mpem. Just wondering thanks storm.

no, MPEM is on EVERY ski-doo sled. DPM is not, DPM is a thing for your carbs. It keeps them properly jetted at all times. (diff temps and air density and whatnot). MPEM is just the sleds computer.
