2015 2500 MM3 curiosity

[HayHay]

I have a 15 model 2500 I bought the truck like it is and I looked under the dash and it has a Mm3 box. It also has the cord to where the monitor would have been. I’m clueless and haven’t delt with them at all of a Cummins in general tbh. The truck is on a really hot tune and I’m wanting to be able to change it. Can I order just a monitor ?? Or?? And if so does it have to be a Mm3 monitor because I couldn’t find just the monitor any where or could a edge insight 3 work?? Sorry if this is obvious I’m clueless on these I’ve just felt with efi live on duramax. Any help would be greatly appreciated!

I have heard of the MM3, but I've been out of the diesel game a while and I always used other programmers so I don't know much about it. Google it up, or YouTube would maybe offer some ideas. Otherwise take it back to where you purchased it and make them figure it out.

This is what I found on the website. Contact them, and hopefully they will fix you up.

I didn’t buy it know tho I bought the truck off a guy and the one before him had it on so I’ve not gotten any way to get ahold of the person who installed it
