DynoDiary

DynoDiary is a mobile + web app for racers and tuners to log, compare, and reproduce dyno and track changes without relying on scattered notebooks, photos, and group chats. Each session captures a structured “run card”: vehicle, mods, fuel, weather, tire pressure, boost targets, timing, AFR, and dyno graph files (or screenshots). The app auto-normalizes key context (SAE/STD notes, ambient conditions) and lets you overlay runs, annotate what changed, and generate a shareable report for customers or teammates. It also includes a lightweight parts-and-map inventory so you can trace exactly which calibration and hardware combo produced a result. This is not a magic tuning tool; it’s a disciplined record system that makes experimentation repeatable and prevents expensive backtracking after a blown session or a customer returns months later asking for “that setup.”
