After installing oversized tires or regearing your vehicle’s differentials to non-stock ratio gears, you’ll likely notice an improper reading on the speedometer, inaccurate MPG estimates, and even poor shift points with an automatic transmission. These issues are typically caused by a miscommunication between your vehicle’s computer and speed sensor, as the factory tune can’t compensate for the altered gearing or RPM. To address these issues, consider a Speedometer & Odometer Calibrator from Hypertech! This premium plug-and-play module offers the same functions as Hypertech’s Max Energy programmers, only without the tuning capabilities. With a simple plug into your vehicle’s OBD2 port, you can navigate the Calibrator’s simple menu to adjust the speedometer and odometer settings, accounting for aftermarket gearing or oversized tires up to 54 inches tall. This product takes only minutes to recalibrate your vehicle’s computer, quickly ensuring accurate readings to get your ride back on the road and operating as intended! Aside from recalibrating, this product features full code reading functionality, allowing you to scan, read, and delete diagnostic trouble codes from your vehicle’s computer. | Hypertech Speedometer Calibrator Programmer 732500
