Can the UCAN scanner display and graph live data?

Yes. The UCAN scanner can display all live data parameters supported by each control module in the vehicle and provides flexible graphing options for real-time visual analysis.

Live Data Display

• View all available PIDs (Parameter IDs) from any control module — engine, transmission, ABS, airbag, body control, and more
• Data updates in real time while the vehicle is running
• Select individual parameters or view multiple parameters at once

Graphing Layouts

• Single large graph: One parameter displayed full-screen for maximum detail and visibility
• Dual side-by-side graphs: Two parameters graphed next to each other for easy comparison — for example, comparing short-term and long-term fuel trim simultaneously
• Quad graph: One large graph with up to four data points plotted together in real time — ideal for monitoring related parameters like all four O2 sensors or multiple temperature readings at once

Why Graphing Matters

Numerical values alone can be difficult to interpret, especially when they change quickly. Graphing live data makes it much easier to spot patterns, spikes, dropouts, and abnormal behavior that would be invisible in a number-only view.
