HIGH-SPEED DATA LOGGING • Ready-made logging presets per engine, plus build-your-own profiles (up to 20 channels) • Boost, intake temps, knock, AFR/lambda, timing and 70+ parameters in real time • Auto-records your pull and saves it as a CSV tagged by VIN, date and time • Powerful viewer — multi-channel overlay, drag-to-read cursor, time-axis zoom and stacked view • One-tap cloud sharing so your tuner can refine the calibration

LIVE HUD Turn your phone into a full-screen instrument cluster while you log. Big, glanceable gauges with per-cylinder knock and misfire, camshaft timing, and automatic over-limit alerts — portrait or landscape, with dedicated layouts per engine. Display only: it never touches your recording.
