It’s great to hear you got everything working correctly. Were you able to identify the root cause of the initial issue? Was it related to pinched wires or something else?
By the way, did you know that you can customize the visual aspects of the graphs in this software? Specifically, the thickness of the graph lines for Channel 1 and Channel 2 can be adjusted within the settings menu. As you modify these settings, the graph display should update in real-time, allowing you to preview the changes. Once you’ve configured them to your preference, these settings will be saved for future use.
One of the primary motivations behind developing this software was the limited graphing capabilities found in most free OBD2 programs. While OBDwiz offered some graphing functionality, it came with frustrating limitations. The most significant drawback was the inability to manually adjust the vertical and horizontal display scales. This auto-scaling feature could often lead to misinterpretations of the data, making normal readings appear abnormal and vice versa. It’s difficult to illustrate without a direct example, but trust me, it could be quite confusing.
In contrast, this software offers a graph (strip chart) mode that includes a valuable Diagnostic Trouble Code (DTC) feature. If a DTC is triggered while the graph is running, the software will display the DTC number directly on the graph. This can be an incredibly useful tool for troubleshooting. For instance, you can wiggle sensor wires while graphing the sensor data and observe if a DTC appears on the graph, pinpointing potential wiring issues.
While some OBD2 software excels at displaying data through dials and gauges, like OBDwiz, this software takes a different approach. If you are interested in exploring the gauge-style display capabilities of OBDwiz, feel free to message me. I can provide detailed instructions on how to install and configure it to work seamlessly with your adapter. However, be aware that it requires specific setup steps to function correctly with certain adapters.
Furthermore, this software incorporates a terminal mode that empowers users to send direct commands to the vehicle’s Powertrain Control Module (PCM) using non-standard formats. This functionality unlocks access to Enhanced Parameter IDs (PIDs), with approximately 260 available for my vehicle. While detailed documentation for these enhanced PIDs is still under development and may be included in a future version, I haven’t encountered any other free OBD2 software that offers this level of advanced command capability.
