I HAVE A 2007 DODGE R3500 THAT I NEED TO CHECK AND POSSIBLY UPDATE PCM SOFTWARE. I HAVE NO EXPERIENCE ON THIS SIDE OF THINGS NEVER PROGRAMMED OR UPDATED A MODULE. I WORK OUT OF AN INDEPENDENT SHOP AND WE TYPICALLY USE OPUS RAP TO DO THIS, BUT THEY LET US KNOW AS OF 3 MONTHS AGO THEY ARE NOT DOING ANYTHING WITH STELLANTIS POSSIBLY GOING FORWARD. ANYWAYS I HAVE THE TOPDON RLINK AND LOOKING FOR GUIDANCE ON HOW TO DO THIS. THANK YOU ALL APPRECIATE YOUR TIME AND INPUT.
