Ram 6.4L trinity use without PCM

2015 Ram 2500 6.4L Power Wagon

Hey guys, I have a Trinity unit laying around from my long gone 2011 Ram 1500. I know to do performance modifications I would need an unlocked PCM, but I was wondering if the Trinity can be used for anything on my current Ram without it. Mostly I am looking for the ability to change tire size and tpms settings. I am upgrading to 35 inch tires soon and would need to recalibrate my speedo. I would rather use the trinity as I already have it in the garage instead of buying a different unit (AEV Procal).

Thanks in advance for the advice.

if the pcm cal is directly supported, you can adjust tire size without the pcm mod.
If it asks for a calibration update, it wont work without modifying the pcm first unfortunately.


Thanks
