A Valentine V1 radar detector with the Savvy Obd2 module is a game-changer. By connecting to the OBD2 port, it gathers vehicle speed data and automatically silences alerts below a preset speed. This feature is incredibly useful for minimizing false alarms in areas saturated with radar signals, like shopping centers. The SAVVY module significantly improves the driving experience with a radar detector.
Expanding OBD2 Functionality
Beyond radar detection, OBD2 offers a wealth of data for performance analysis and vehicle diagnostics. TrackAddict, a popular iPhone app for recording autocross sessions, leverages this data. When paired with a WiFi-enabled ELM327 OBD2 reader, TrackAddict captures critical information like RPM, speed, throttle position, and boost alongside video and GPS data. This data can be compiled directly on the phone or exported for in-depth analysis using software like RaceRender2. Affordable ELM327 units are readily available online, providing a cost-effective way to access this valuable data.
Managing Multiple OBD2 Devices
Using multiple OBD2 devices simultaneously, such as a SAVVY module and a WiFi reader, requires a solution beyond a simple splitter. Standard splitters often result in devices competing for connection, leading to intermittent functionality. A more effective approach involves a custom solution using a SPDT (Single Pole Double Throw) switch wired to pin 16 of the OBD2 connector, which controls power delivery. This allows for manual selection between connected devices, ensuring consistent performance.
DIY OBD2 Selector Switch Installation
Creating a custom OBD2 selector switch requires some basic wiring knowledge and readily available components. An OBD2 splitter cable, a SPDT switch, wiring tools, and a Dremel tool are necessary. The process involves identifying and severing the power wire (pin 16, typically green/white) within the splitter cable. This wire is then connected to the SPDT switch, enabling power to be directed to either connected device. For a clean installation, the switch can be discreetly mounted inside the vehicle’s interior, such as within a storage compartment. This provides easy access for switching between devices without compromising the vehicle’s aesthetics.
Concealed Installation for Seamless Integration
For a truly integrated solution, the SAVVY module can be hidden within the dash, leaving the WiFi OBD2 adapter and selector switch accessible. Utilizing existing storage compartments allows for concealed installation, maintaining a clean and organized interior. Minor modifications to the compartment, such as drilling a small hole for the switch and cable routing, may be necessary. This approach ensures all components are neatly integrated without impacting the vehicle’s appearance or functionality.
