DynoDiary

DynoDiary is a mobile + web app for tracking mod changes and validating whether they actually improved performance. Users log each modification (part, install date, cost, tuner/shop, baseline) and attach evidence like dyno sheets, dragy/track times, OBD logs, and ambient conditions. The app normalizes runs by correcting for temperature/altitude where possible and flags “bad comparisons” (different tires, fuel, heat soak, etc.). It generates a clean, shareable build page that focuses on before/after deltas and confidence level, not just a parts list. Shops can create verified installs and upload dyno results to reduce disputes and build credibility. This is not another social feed; it’s a lightweight proof-and-history tool that helps enthusiasts stop wasting money on mods that don’t move the needle.
