The era of the Module Programmers is over. After years of mystery about what these people do and how they do it, the fog of war has finally cleared - and the module programming methodology is now a quantifiable and learnable skillset. This is what Tester Engineering Suite is at it's core - its an educational tool that teaches the average mechanic deeper level systems within the automotive sphere. So apologies to the Module Programmers, you have been automated and made redundant.

Introducing a new experimental capability in Tester Engineering Suite - Acoustic Diagnostics. It turns the laptop's built-in or a USB microphone into a live engine stethoscope — capturing sound in raw mode (bypassing Windows mic effects), running a real-time FFT, and displaying a spectrogram, spectrum, and RPM-locked crank-order cursors (fed from the OBD link) with record/replay and healthy-baseline A/B comparison — so a technician can see which noises track the engine and how a suspect one differs from known-good.
