Default heating problem need help

I need your help. I have a 2006 2500 Ram and having trouble with my cummings. We are located in nebraska and its cold. My pickup will not heat up but going down the road it may go up to 190 then down to 140 then when i stop its below that. I had a new theromstate and clutch fan put on it and it didnt help . Also my tach is reading almost nothing at idle..Could this be my ecm, does it need to be flashed.

It is cold ....and could use your help.
