In the fast-paced world of modern trucks, OTR Diagnostics' live data feature provides real-time information of your truck's operations. Want to monitor your exhaust temperatures during regeneration?

I'm. Y'all seriously need to fix the issue with not remembering the Bluetooth thingy. This has worked flawlessly for almost 3 years, maybe it's been 4. The new update thing.... No. Let me go back. The way back machine. Fire it up and let's take a trip back to simpler times. You with me? Ok, come on. Load up. That's it. Buckle up. We are going back, way back.
