Hi, I have a 2004.5 2500 Cummins with the It’s bone stick with a straight pipe. I recently bought a brand new smarty touch tuner and I got it all hooked up and I can’t get it to tune my truck. When I hit the ecm button to go to where I would tune it, it pops up an error and says “ecm not in application mode”. I have no idea what it could be but I’m hoping someone has had a similar problem and may know what I can do to fix it. I’d hate to waste $900 on a tuner for nothing. I’ve tried to contact smarty resource for over a month by calling, emailing, and leaving voicemails but no answer and no reply. I’m not happy with their customer service at all. Any help would be appreciated. Thanks
