Understanding Fuel Pressure Readings With The Torque App

The Torque app can be used to monitor fuel pressure, but there are some limitations. The app can display fuel rail pressure, fuel pressure, and fuel tank pressure. However, the availability of this data depends on the vehicle's ECU, and some vehicles may not provide this information to the OBD2 port. Additionally, the accuracy of the data may vary, and in some cases, it may be necessary to use a more advanced OBD dongle and software to get more accurate readings. It is also worth noting that some vehicles may not have a fuel pressure sensor, which is required for the Torque app to read fuel pressure.

The Torque Pro app can display fuel rail pressure

To see if your vehicle is compatible with the Torque Pro app, you can consult a known site like Edge and see what PIDs are available for your truck. If rail pressure is reported for your truck, then the app should be able to display it.

In addition, you will need to purchase a Bluetooth OBD reader to connect your phone to your vehicle. Once you have the appropriate OBD reader and have confirmed that your vehicle is compatible, you can set up the Torque Pro app to display fuel rail pressure.

The specific steps to do this may vary depending on your vehicle, but in general, you will need to open the app and select the "Add Sensor" or "Create Gauge" option. From there, you can select "Fuel Rail Pressure" from the list of available parameters.

It's important to note that even if you have the app and the OBD reader, your vehicle may not report fuel rail pressure. In that case, you will not be able to see the data in the app, as the app can only display data that is available from the vehicle.

The app can also show fuel pressure and fuel tank pressure

The Torque app can display fuel pressure and fuel tank pressure. However, this is only possible if the relevant information is made available by the ECU. For example, the ECU in a Pontiac Solstice only makes fuel rail pressure available at the OBD2 port, meaning that Torque cannot display fuel pressure or fuel tank pressure for this vehicle.

If you have a Ford vehicle, you can add the extended Ford PID list to Torque to display the actual fuel rail pressure. Alternatively, you can use Forscan Lite, which has every PID available from the get-go and can display rail pressure and much more.

It's important to note that some vehicles may not have a fuel pressure sensor, in which case you would need an actual fuel pressure gauge to measure the fuel pressure.

The app may not work with all vehicles

The Torque app is designed to work with any OBD2-compliant vehicle. OBD2 compatibility generally applies to petrol/gasoline vehicles built from 1996 onwards and diesel vehicles from 2004 onwards, although some manufacturers like VW implemented this standard as early as 2001 for some diesel models.

However, there may be cases where the app does not work with all vehicles, even if they are OBD2-compliant. This could be due to various factors, such as the specific make and model of the vehicle, the availability of certain sensors or adapters, or compatibility issues with the app.

For example, in some Ford Truck models, the Torque Pro app cannot read fuel pressure because there is no fuel pressure sensor for the app to connect to. Similarly, in certain Pontiac Solstice models, the ECU does not make fuel pressure information available to the OBD2 port, resulting in zero readings on the Torque app.

It's important to note that the app's functionality may also depend on the user's device and operating system. For instance, the Torque Pro app is available on the Google Play store but not on iOS. Additionally, some users have reported issues with specific adapters, such as the PLX adapter, not working correctly due to various bugs, particularly on the Ford J1850PWM protocol.

To ensure compatibility, it is recommended to refer to the list of adapters known to work with Torque and to check that the vehicle is OBD2-compatible before attempting to use the app.

You can add custom PIDs to the app

To see fuel pressure in the Torque app, you need to have the extended Ford PID list added to Torque. This will allow you to view the fuel rail pressure.

You can add custom PIDs to the Torque app. To do so, you will need to download the Torque OBD2 app and connect it to your Bluetooth OBD2 scan tool. Go to your OBD2 adapter settings and set the connection type to "Bluetooth". Then, click on "Choose Bluetooth Device" and select "OBD-AUS".

Return to the app home screen and wait for the flashing blue icons to turn solid. To check if the app is connected to the ECU, look for the RPM reading on the screen. Go to "Settings" and then "Manage Extra PIDs/Settings". You will see available settings on the screen, but you want to go to "Add Custom PID" on the options button. Click "Ok".

The OBD2 PID Editor screen will appear, where you will enter the information, including the Long Name, Short Name, Min./Max. Value, Equation, Unit Type, and Scale Factor. Leave the other fields blank.

Click on "Test". If it doesn't work, make sure that the details you entered are correct.

Note that you will need the paid version of Torque to enter PIDs. Also, keep in mind that the data you can extract depends on the brand and model of your vehicle.

• Fan Speed of a 2002 Trailblazer: 22162B (with "01" appended for faster response)
• Desired Fan Speed: 22163F (with "01" appended for faster response)
• A/C High Pressure: 221144 (append "01" for faster response)
• Engine Oil Temperature: 221154 (append "01" for faster response)
• Gen F Terminal Signal: 22114D (append "01" for faster response)
• Manifold Absolute Pressure Sensor: 221142 (append "01" for faster response)
• Ignition 1 Signal: 221141 (with the option to append "01" for faster response)

The app can be used with a Bluetooth OBD reader

The Torque app can be used with a Bluetooth OBD reader to provide real-time data about your car's performance and diagnostics. It connects to your OBD2 engine management/ECU and offers a range of features, including a customizable dashboard, GPS tracker logs, fault code reading and reset, horsepower and torque dyno, transmission temperature readings, and more.

To use the app, you will need to purchase a Bluetooth OBD2 adapter, also known as a scanner or reader, that is compatible with the app. These adapters are small and plug into the diagnostics socket on your car, giving your phone access to various sensors and data. While there are many adapters available, not all of them are created equal. It is recommended to buy from reputable brands to ensure a good experience and avoid connection issues. Some of the best reliable OBD2/OBD adapters include the Scantool.net adapter, the OBDKey, and PLX Devices OBDLink.

When choosing an adapter, it is important to note that some adapters may not be compatible with your vehicle's ECU, so it is always good to check with your manufacturer first. Additionally, some adapters may offer faster read speeds, which can be beneficial for certain use cases. The OBDLink series of adapters, for example, offer the fastest PID read speed over Bluetooth.

Once you have your adapter and have connected it to your vehicle, you can then pair it with the Torque app on your phone. This will allow you to access various parameters and sensors, depending on what your vehicle's ECU makes available. For example, you can view fuel rail pressure, fuel pressure, and fuel tank pressure, but only if your ECU provides that information to the OBD2 port.

With the Torque app and a Bluetooth OBD reader, you can turn your smartphone into a powerful tool for monitoring and diagnosing your vehicle's performance and health.
