Review: boa qualidade
Review: I used this adapter with the JScan app to recalibrate my Jeep JL’s speedometer after upgrading to larger tires and adding a lift kit, and it worked flawlessly. It connected to my OBD reader with no issues, synced with the app right away, and let me adjust the speedometer accurately on the first try. No random disconnects, no errors, and the changes saved exactly the way they were supposed to. If you’ve changed tire size, gearing, or suspension height and need a reliable way to dial your speedometer back in, this adapter is solid.
