The world of automotive diagnostics can seem complex, but tools like the UltraGauge OBD2 scanner are designed to simplify understanding your vehicle’s health and performance. Whether you’re a seasoned mechanic or a car owner keen on preventative maintenance, an OBD2 scanner is an invaluable asset. UltraGauge stands out as a user-friendly option, providing real-time data and diagnostic capabilities directly from your car’s onboard computer. While the UltraGauge Blue wireless version is no longer available, the robust wired UltraGauge EM PLUS and MX models continue to offer powerful features for monitoring your vehicle. This article will guide you through the capabilities of UltraGauge OBD2 devices, focusing on the still-available wired options and referencing the discontinued wireless version for feature comparison.
UltraGauge Wired: Reliable and Direct OBD2 Access
The UltraGauge EM PLUS and MX represent the wired iteration of this popular OBD2 scanner, offering a straightforward and dependable way to access your vehicle’s data. These devices are designed as all-in-one solutions, meaning everything you need is contained within the unit itself – no need for smartphones or apps to operate. This self-contained nature ensures they are always ready and present, seamlessly integrating into your car as permanent instrumentation, much like your existing instrument panel.
Connectivity is a key strength of the wired UltraGauge. It establishes a constant and direct connection to your vehicle’s OBD2 port. Once plugged in, it’s always connected and actively monitoring, requiring no further user intervention to establish communication. Power for the UltraGauge wired models is drawn directly from the OBD2 port, and it’s engineered for minimal power consumption, even entering an ultra-low power mode when the ignition is off. This efficient power management allows the UltraGauge to remain permanently connected without risk of battery drain.
Updates for wired UltraGauge devices are less frequent and require sending the unit back to the factory. While this is a less convenient process compared to wireless updates, the focus of the wired versions is on rock-solid reliability and essential functionality, minimizing the need for frequent updates. In terms of capabilities, the wired UltraGauge prioritizes simplicity and efficiency. It features a clear monochrome display presenting digital text gauges, focusing on essential data parameters in an easy-to-read format. You can customize the display to show 4, 6, or 8 gauges per page, allowing you to monitor the most critical information at a glance. The connection is established and maintained through the OBDII cable, which provides both power and data communication.
A Look Back: UltraGauge Blue Wireless (Discontinued)
Although discontinued in early 2022, understanding the UltraGauge Blue wireless version provides valuable context when considering OBD2 scanner features. UltraGauge Blue represented a wireless approach, pairing an OBD2 adapter with a mobile application on your Android or Apple device to create a complete diagnostic solution.
One of the key advantages of the UltraGauge Blue was its automatic connection. Whenever your mobile device with the app was within range of the Bluetooth adapter plugged into your OBD2 port, it would connect automatically, eliminating any manual pairing steps. Like the wired versions, the UltraGauge Blue adapter was designed to be always present and active, becoming a permanent part of your vehicle’s instrumentation. While the adapter itself was always in place, you had the flexibility to use your primary mobile device when needed or dedicate an older smartphone as a permanent display. Power consumption for the adapter was also minimal, similar to the wired versions, posing no battery drain concerns. However, the mobile device needed to be powered separately, typically via a USB power adapter.
A significant advantage of the wireless UltraGauge Blue was its update capability. Both the mobile app and the OBD2 adapter could be updated by the user, allowing for frequent feature enhancements and improvements. These updates, both minor and major, were provided free of charge throughout the product’s lifespan. In terms of features, the wireless platform offered “nearly unbounded future capabilities” compared to the wired versions at the time of its release. The mobile app enabled beautiful color, high-resolution displays, allowing for digital and analog gauges, graphing capabilities, icons, advanced graphics, and extensive customization of each gauge. You could display between 1 and 10 gauges per page, choosing from digital readouts, analog-style gauges, graphs, or alert icons, offering a highly visual and customizable experience. Communication between the app and the adapter was wireless via Bluetooth, while the mobile device could utilize Wi-Fi or mobile data for internet connectivity, enabling potential future features like cloud data logging and real-time information access.
Wired vs. Wireless UltraGauge: Choosing Your Ideal OBD2 Scanner
Choosing between the wired UltraGauge EM PLUS/MX and the now-discontinued wireless UltraGauge Blue mirrors the decision of selecting a dedicated GPS navigation device versus using a navigation app on your smartphone. Wired UltraGauge devices provide a dedicated, always-on, and simplified experience, focused on core OBD2 monitoring functions. They are robust, reliable, and require no additional devices to operate. UltraGauge Blue, on the other hand, offered a more feature-rich and visually dynamic experience through its mobile app interface, along with wireless convenience and user-updatable software.
| Feature | Wired (UltraGauge EM PLUS & MX) | Wireless (UltraGauge Blue) DISCONTINUED |
|---|---|---|
| Display | Monochrome, Digital Text | Color, Digital & Analog, Graphing |
| Connection | Direct OBDII Cable | Bluetooth Wireless to Mobile Device |
| Updates | Factory Return Required | User-Updatable App and Adapter |
| Gauge Variety | Digital Text Only | Digital, Analog, Graphs, Icons |
| Gauges per Page | 4, 6, or 8 | 1-10 |
| Complexity | Simpler, Dedicated Device | More Complex, Mobile App Dependent |
For users seeking a straightforward, no-frills OBD2 scanner that is always ready and permanently installed, the wired UltraGauge EM PLUS or MX are excellent choices. If you were drawn to the advanced visual features, customization, and wireless connectivity of the UltraGauge Blue, you might consider exploring current wireless OBD2 scanner options available on the market that offer similar smartphone-based interfaces and functionalities.
UltraGauge: Your Automotive Information Center
Regardless of the wired or wireless approach, UltraGauge devices are fundamentally automotive information centers and powerful OBD2 scan tools. They go beyond simply reading trouble codes; they empower you to monitor a wide array of engine parameters in real-time. This includes critical data like coolant temperature, oxygen sensor voltage, intake manifold pressure, RPM, intake air temperature, boost pressure, and ambient air temperature. Furthermore, UltraGauge provides valuable fuel usage gauges, such as average MPG, instantaneous MPG, distance to empty, fuel tank level, and time to empty, helping you optimize fuel efficiency.
And of course, UltraGauge functions effectively as a trouble code scanner (code reader). It can read and display diagnostic trouble codes, providing insights into potential issues. Crucially, UltraGauge allows you to clear these trouble codes and turn off the check engine light, potentially resolving minor issues yourself and saving trips to the mechanic.
UltraGauge is known by many names in the automotive world, often referred to as an auto scanner, Bluetooth receiver (though wired versions are not Bluetooth), OBD2 scanner, OBD scanner, scan tool, code reader, trouble code reader, diagnostic code reader, mileage gauge, MPG gauge, scan gauge, auto diagnostic tool, and more. Ultimately, UltraGauge serves as a comprehensive information hub for your vehicle.
