For many Subaru Impreza Sport owners, a common desire is to see more vehicle data displayed than what the factory infotainment screen offers. While the screen is capable, it lacks fundamental gauges like a temperature gauge, oil pressure gauge, or voltmeter. Knowing that the car monitors these parameters, the question arises: can this data be accessed and displayed more effectively, perhaps using a multi-function display? This exploration delves into the possibilities of utilizing factory Subaru parts and OBD2 systems to enhance data visibility in an Impreza.
Factory Subaru Multi-Function Display Options
Subaru has incorporated multi-function displays in various models, including the Impreza, Forester, Ascent, and Crosstrek. Parts catalogs reveal several part numbers associated with these units, such as 85261FL— or 85263FL—, and specifically 85261FL021. These part numbers suggest a degree of commonality across different models and years.
Notably, Impreza models themselves seem to have variations of these displays. Pictures indicate versions with single-color push buttons and others with multi-color displays, suggesting different feature levels or model year updates.
WRX Specific Display Considerations
The 2021 WRX utilizes a distinct multi-function display unit, part number 85263VA020. Initial research suggests this version might offer enhanced features, possibly including a boost monitor, relevant for the WRX’s turbocharged engine. However, it’s unclear if this display is standard across all WRX trim levels. A key question is the extent of wiring differences between the WRX and Impreza for these displays.
OBD2 and Aftermarket Display Alternatives
While factory displays are intriguing, numerous alternative methods exist to monitor vehicle data. These include:
- Dedicated OBD2 gauge pods: External displays that plug into the OBD2 port and present real-time data.
- OBD2 Bluetooth adapters: Devices that transmit vehicle data to smartphones or Android Auto head units.
- Direct sensor wiring: A more traditional approach involving direct wiring from sensors to aftermarket gauges.
However, the focus here remains on the potential of the existing multi-function display location in the Impreza. The central question is not if gauges can be added, but how to utilize the factory display or a compatible unit.
Key Compatibility Questions
Two fundamental questions arise when considering a factory multi-function display upgrade:
Display Feed Source: Infotainment or Gauge Cluster?
Understanding the data source for the display is crucial. Is the display driven by the main infotainment unit, or does it receive information directly from the gauge cluster or vehicle CAN bus? The answer dictates compatibility and the complexity of any potential swap. A standalone display would simplify matters significantly.
WRX Unit Swap Viability
If the data feed issue can be resolved, the next logical step is to consider swapping a WRX multi-function display into an Impreza or other compatible models. However, the value of such a swap depends on whether the necessary data is even available to feed the display in different models, regardless of physical compatibility.
Conclusion: Academic Curiosity and Practical Exploration
Currently, these questions remain largely academic, driven by a fascination with the modularity and sometimes perplexing nature of automotive design and parts systems. The limited detail in parts diagrams adds to the challenge. Further investigation is needed to determine the feasibility of upgrading an Impreza with a more informative OBD2 multi-function display, potentially leveraging existing factory components.
