Open-source iRacing telemetry lib measures understeer per corner phase with zero AI

JeremyCMorgan · x · 2026-11-05

harryspitbox-core (C#, MPL-2.0) is the open-source measurement core of Harry's Pit Box, an iRacing setup and driving coach. It reads .ibt telemetry files, detects corners from the car path, splits each into entry/mid/exit phases, and computes an understeer angle per phase, plus balance, slides, laps and runs. The README stresses no AI is involved—just measurement and plain, readable rules.
