Good news for car enthusiasts and Megasquirt users! You might be wondering, Does Megasquirt Have Obd2 compatibility? The answer is yes! With the introduction of a new module, Megasquirt MS2 and MS3 ECUs can now communicate via the OBD-II protocol through the CAN bus, opening up a world of possibilities for monitoring your engine’s performance.
Real-Time Data at Your Fingertips with Megasquirt OBD2
This exciting development means you can now connect any standard OBD-II reader to your Megasquirt setup and access real-time engine data. Imagine being able to monitor crucial parameters like:
- RPM (Revolutions Per Minute)
- MAP (Manifold Absolute Pressure)
- TPS (Throttle Position Sensor)
- CLT (Coolant Temperature)
- IAT (Intake Air Temperature)
- VSS (Vehicle Speed Sensor – MS3 only)
- Timing Advance
- AFR (Air-Fuel Ratio)**
- EGO Correction (Short Term Fuel Trim)**
- Barometric Pressure (requires a baro sensor in your ECU)**
- Knock Retard**
** Note: Features marked with double asterisks may require devices that support extended PIDs, such as the ScanGauge-II.
Expanding Your Megasquirt Monitoring Options
The integration of OBD-II on Megasquirt MS2/MS3 unlocks a range of new monitoring and display options:
- Dedicated Gauges: Install a ScanGauge-II for a compact display of up to four real-time parameters.
- Smartphone Connectivity: Use an OBD-II Bluetooth adapter to connect your Megasquirt to Android devices and apps like Torque, providing comprehensive data visualization on your phone or tablet.***
- Universal Datalogging: Leverage the vast ecosystem of OBD-II datalogging devices for in-depth performance analysis.
- Broader Gauge Compatibility: Integrate gauges and digital dashes that support the widely adopted OBD-II protocol, even if they don’t natively support the MS CAN protocol.
*** Important Note: While OBD-II Bluetooth adapters offer convenience, reliability can vary. Wired connections are generally recommended for the most stable data access.
Important Considerations: Emissions and Diagnostics
It’s crucial to understand that while this module provides OBD-II data output, it is not designed to bypass or fake emissions tests. Currently, the system does not support the output of Diagnostic Trouble Codes (DTCs). The focus is on providing valuable real-time data for performance monitoring and engine tuning.
Conclusion: OBD2 for Megasquirt – A Game Changer
The addition of OBD-II compatibility to Megasquirt MS2 and MS3 is a significant enhancement. It empowers users with greater flexibility in how they monitor their engine’s performance by tapping into the extensive world of OBD-II devices and software. Whether you prefer dedicated gauges, smartphone apps, or advanced datalogging, Megasquirt with OBD2 opens up a wide array of possibilities for engine management and data analysis.
