Are you looking for a budget-friendly way to correct your speedometer and potentially mileage readings after upsizing your tires or making other modifications to your vehicle? Many car enthusiasts, especially truck owners who frequently customize their rides, face this issue. Fortunately, a simple and inexpensive solution exists using an Android Mileage Correction Tool Obd2. This article will guide you through using a Bluetooth OBD2 module with an Android app to achieve accurate speed readings and understand how it relates to mileage.
Understanding OBD2 for Mileage and Speed Correction
OBD2 (On-Board Diagnostics II) is a standardized system in modern vehicles that allows access to a wealth of data from your car’s computer. Primarily designed for emissions monitoring and diagnostics, OBD2 ports can also be leveraged for various other functionalities, including reading real-time parameters and, in some cases, making adjustments. When it comes to speedometer and mileage, the vehicle’s computer relies on sensor data, often from the wheel speed sensors, to calculate these values. Changing tire sizes, for instance, can throw off these calculations, leading to inaccurate readings. This is where an android mileage correction tool obd2 comes into play.
Choosing the Right OBD2 Tool and App for Android
For this DIY mileage and speedometer correction method, you’ll need two key components: a Bluetooth OBD2 scanner and a compatible Android app. The author of the original post discovered a highly affordable and effective option: the Veepeak OBDCheck BLE Bluetooth OBD II Scanner.
This scanner, readily available on platforms like Amazon, is praised for its low cost and broad compatibility. It pairs seamlessly with Android devices via Bluetooth and works with numerous OBD2 apps. For this specific purpose, the OBD Fusion app is recommended due to its user-friendly interface and robust features, including the ability to adjust speed readings. While there are free OBD2 apps available, OBD Fusion, costing a nominal fee, offers a more comprehensive suite of features and reliable performance, making it a worthwhile investment for serious car enthusiasts.
Step-by-Step Guide: Correcting Speed Readings with OBD Fusion and Veepeak OBD2
Once you have your Veepeak OBD2 scanner and the OBD Fusion app installed on your Android device, the process of correcting your speed reading is straightforward:
- Connect the OBD2 Scanner: Locate the OBD2 port in your vehicle (typically under the dashboard on the driver’s side) and plug in the Veepeak OBDCheck BLE scanner.
Connecting the Veepeak OBD2 Bluetooth adapter to the OBD2 port for Android mileage correction using the OBD Fusion app.
- Pair with Android Device: Enable Bluetooth on your Android device and pair it with the Veepeak OBD2 scanner. The app will guide you through this process.
- Launch OBD Fusion and Connect: Open the OBD Fusion app and establish a connection with the OBD2 scanner.
- Navigate to Vehicle Settings: Within the app, typically under “Settings” or “Preferences,” look for “Vehicle Editor” or similar vehicle-specific settings.
- Adjust Vehicle Speed Scale Factor: Scroll down to find the “Vehicle Speed Scale Factor” setting. This is where you’ll input a correction factor to adjust the speed reading. The app uses percentages for adjustment, making it adaptable to various tire size changes.
- Calculate and Input Scale Factor: For larger tires, you’ll need to increase the scale factor. As a starting point for 35-inch tires, a scale factor of 1.15 or 1.16 is suggested. You may need to fine-tune this value by comparing your app’s speed reading with a GPS speedometer app to achieve accuracy.
- Real-time Monitoring: OBD Fusion allows you to create a customizable dashboard displaying real-time parameters. You can add “Corrected Speed” alongside other readings like boost, coolant temperature, and more, turning your Android phone into a digital gauge cluster.
Important Note: It’s crucial to understand that this method corrects the speed reading within the OBD Fusion app itself, not on your vehicle’s physical speedometer. The vehicle’s odometer will still accumulate mileage based on the uncorrected sensor readings. However, for users primarily concerned with accurate speed readings within the app and understanding their actual speed, this is a highly effective solution. Some might even see the slower odometer accumulation as a minor benefit.
Alternatives and Considerations: Banks iDash and Warranty
While the Veepeak OBD2 and OBD Fusion combination is a cost-effective android mileage correction tool obd2 solution, there are more advanced options available. The Banks iDash is mentioned as a more premium alternative. However, at a significantly higher price point, it might not be justifiable for users solely seeking speedometer correction, especially if they are not invested in other Banks performance products. The iDash’s primary appeal lies in its integration within the Banks ecosystem, particularly for users with Banks tuners and pedal commanders.
Another important consideration, briefly touched upon in the original post, is vehicle warranty. Modifications, even seemingly minor ones like tire size changes or adding leveling kits, can potentially raise warranty concerns with dealerships. While laws generally protect consumers, requiring manufacturers to prove modifications caused the issue, disputes can be time-consuming and resource-intensive. Using an OBD2 scanner for speed correction is unlikely to void your warranty, but it’s always wise to be aware of potential implications of any vehicle modifications.
Conclusion: Affordable and Functional Speed Correction with Android OBD2
For DIY car enthusiasts looking for an android mileage correction tool obd2, the combination of a Veepeak OBD2 scanner and the OBD Fusion app provides an excellent balance of affordability and functionality. It offers a straightforward way to monitor and correct speed readings within the app, providing valuable real-time data and customization options. While it doesn’t alter the vehicle’s odometer reading, it addresses the need for accurate speed information, especially after tire size changes, at a fraction of the cost of more elaborate systems. This solution is particularly appealing for those who appreciate DIY modifications and want to keep a close eye on their vehicle’s performance parameters without breaking the bank.
