WaveWrench Pro Guides

Why a weak battery or noisy alternator invalidates every downstream diagnosis, and the checklist to verify both before you scope.

What a scope does, choosing probes, safe hookup, and the patterns that matter most.

Pick the right trigger mode and timebase so the event you care about lands on screen.

Read starter, injector, and parasitic-draw currents without breaking any circuit.

Firing line, spark line, coil oscillations — decode secondary and COP patterns.

Voltage and current signatures for saturated and peak-and-hold injectors.

Find a dead cylinder in five minutes with a starter current capture.

Capture CAN-H and CAN-L, check termination, and spot bus-off and voltage faults.

Use reference patterns (including PicoScope waveforms) to spot timing, amplitude, and integrity deviations.

What a lab scope does, how to hook it up, and the three-pass method for reading any automotive waveform.

One command converts a whole folder of protected .psdata captures into CSV files that load instantly in the analyzer.

Glitch triggers, roll mode, deep memory, and unattended captures.

What noises to trust, how to record them cleanly, and how to feed them into the analyzer.

Step-by-step checklist for recording clips and gathering data so the AI gives its best diagnosis.

Tell spark knock, rod knock, main rumble, piston slap, and wrist-pin tick apart.

Serpentine squeal, tensioner rattle, chain slap at cold start, VVT actuator tick.
