i got a buddy that just bought a rev with dpm, and we were all trying to figure out exactly what it does, someone said that it changes jetting for altitudes, one said temps, so i've heard a few diff things, can anyone tell me exactly what it does?

Changes jetting automatically for altitude.

Dootalk has lots of info on it you can search up. My ho has it so I looked it up. It saves trouble of changing your jets but, from what I read, is basically worthless under 5000 feet. It might save a minor change in jetting in temps (like -10 one weekend to 30 the next), which usually isnt that necessary.

But in the end, your always gonna be running optimaly jetting wise. Pulled the plugs on mine when I first got my sled couple months ago because it looked like they had been in there for awhile, and both were a nice light brown. Exaclty where you want it.

That brings up an interesting thought. Would DPM save you from going through a lot of plugs like you'll normally do??

^^^ If you are not jetted right then you could ruin plugs or worse your engine so technically yes it could save plugs, but if you are worried about plugs and are a flat lander and they are burning out constantly it most likely isnt from jetting but something else. Or just makeing sure your jetting is right once a year in most cases will be much more benefical than spending $300 on DPM over a few bucks for two jets.

DPM compensates for both altitude and temperature.
