Encountering problems with your BAFX OBD2 adapter and Torque Pro app, specifically around RPM readings? Many users face issues where RPMs are the only seemingly accurate data point, while other sensors like speed, coolant temperature, and boost display incorrect or no information. Let’s diagnose these common problems and explore potential solutions.
One frequent message is “ECU Problem. The ECU is reporting that it does not support the reading of any PIDs.” This can be misleading, especially if you see “connected to ECU OK” and RPMs are registering. It often doesn’t mean your vehicle is not OBD2 compliant, even for models around the mid-90s. The issue is more likely related to how Torque Pro is configured to read your specific vehicle’s data (PIDs – Parameter IDs).
Inaccurate readings like speed showing double the actual value or coolant temperature stuck at -40F, along with boost at zero, indicate incorrect PID settings. Torque Pro needs to be properly configured for your car’s ECU to interpret the signals correctly. The fact that RPMs are working suggests the OBD2 connection itself is functional, but the data interpretation for other sensors is flawed.
Another reported problem is engine stalling when scanning for faults while running. This could be due to communication issues or the way the ECU handles diagnostic requests via the OBD2 port. Scanning for faults with the key in the ‘on’ position but the engine off is generally a safer practice to avoid unexpected shutdowns.
While some users explore “Power Stroke PIDs,” this is usually specific to Ford Power Stroke diesel engines and might not be relevant to your vehicle. Instead of focusing on specific engine types initially, the key is to ensure basic OBD2 and Torque Pro setup is correct.
To troubleshoot, start by verifying your vehicle’s OBD2 compliance based on the model year. Then, within Torque Pro, explore connection settings and vehicle profiles. Ensure the correct protocol is being used for OBD2 communication. If RPMs are the only reading, you may need to manually input or adjust specific PIDs for other sensors within the Torque Pro app settings to get accurate readings for speed, temperature, boost, and other parameters beyond just “Bafx Obd2 Torque Pro Rpms”.
