The Dash Hawk Obdii Reader is a powerful diagnostic tool for car enthusiasts and professionals alike. This comprehensive review delves into its extensive capabilities, exploring the various parameters it can monitor and addressing its current limitations. We’ll cover everything from engine performance data to potential mounting challenges.
Unlocking a Wealth of Vehicle Data with the Dash Hawk
The Dash Hawk provides access to a wide array of engine parameters, offering valuable insights into your vehicle’s performance. Some key data points accessible via the Dash Hawk include:
- Engine Diagnostics: Trouble codes, calculated load, engine coolant temperature, short/long term fuel trims (Bank 1), manifold absolute pressure (MAP in kPa), engine RPM, vehicle speed, timing advance, intake air temperature, mass airflow (grams per second), and more.
- Emissions System: Number of O2 sensors, O2 Bank 1 sensor 2 readings, engine run time, MIL (Malfunction Indicator Lamp) on distance, catalytic converter temperature (Bank 1, Sensor 1).
- Fuel System: Diesel fuel pressure command, fuel level, warm-up counts.
- Other Crucial Data: EGR duty cycle command, evaporative purge duty cycle, distance since DTCs cleared, barometric pressure, module voltage, absolute load command, equivalence ratio, relative throttle position, ambient air temperature, absolute throttle positions (A & B), absolute pedal positions (D & E), commanded throttle actuator, knock sensor readings (1 & 2), knock retard, and multi-display system status.
This comprehensive data allows for in-depth analysis of engine performance, emissions, and various other critical systems.
Addressing Limitations and Future Enhancements
While the Dash Hawk boasts impressive capabilities, it’s important to acknowledge its current limitations. As of now, the device doesn’t directly display boost in pounds per square inch (PSI). Instead, it provides Manifold Absolute Pressure (MAP) readings in kilopascals (kPa). Users will need to convert these readings to PSI using a separate formula. Furthermore, fuel pressure readings are not currently available in PSI.
The manufacturer, MSD, is aware of these limitations and is actively working on solutions. Future updates are planned to address the need for boost and fuel pressure readings in PSI. Additionally, an add-on module and software update are in development to enable support for Exhaust Gas Temperature (EGT) readings using a standard K-type thermocouple. This enhancement is expected within the coming months.
Mounting Considerations for the Dash Hawk
The Dash Hawk features a four-foot OBDII cable that plugs directly into the back of the unit, requiring careful consideration for mounting location. The straight connector design prevents flush mounting unless a custom hole is drilled to accommodate the cable. A simple plastic mount and double-sided tape are included. However, finding an ideal mounting spot can be challenging, especially in vehicles with limited dashboard space.
Dash Hawk: A Powerful Tool for Automotive Diagnostics
The Dash Hawk OBDII reader offers a wealth of information for diagnosing and understanding vehicle performance. While certain limitations exist, the manufacturer is committed to continuous improvement and future updates promise enhanced functionality. For enthusiasts and professionals seeking a comprehensive diagnostic tool, the Dash Hawk remains a compelling option.
