Scope & Pinpoint
Your scope is one of the most powerful diagnostic tools in the shop. But it’s only as good as your ability to read what it’s telling you. Our built-in library gives you known-good waveforms to compare against — so you know what right looks like.
Diagnostic Categories
Each category contains known-good waveforms, and known bad, common failures, test procedures, and real-world examples. Click a category to explore.
Baseline Testing
Relative Compression (RC) and Volumetric Efficiency (VE). The first test you should run on any engine performance concern. Establishes whether the engine can do its job.
Explore →Cam and Crank
CKP and CMP signal analysis. Verify timing relationships, detect stretched chains, jumped timing, and sensor issues. The heartbeat of the engine.
Explore →In Cylinder
Pressure transducer testing — cranking and running compression waveforms. See valve events, combustion, and mechanical issues that a gauge can't show you.
Explore →CAN Bus
Network communication testing. Verify CAN High/Low signals, check for open circuits, shorts, and module communication failures.
Explore →Electrical, Alt and Draw
Electrical and Parasitic draw testing and current analysis. Find what's draining the battery using amp clamp patterns and sleep mode monitoring.
Explore →Amp Analysis
Current ramp testing for fuel pumps, injectors, ignition coils, starters, and more. Non-invasive testing that tells you what's happening inside components.
Explore →Misc (Coolant, NVH)
Additional scope patterns, sensor testing, and reference waveforms that don't fit neatly into one category but are still essential knowledge.
