Day 1 — First Contact & Baseline Review

3 logs analyzed · 14 minutes of logged data · 2 stall/restart events detected

What this day established The project's log-analysis methodology was built here: parsing tab-delimited MSL exports, identifying the RPM/CLT/TPS columns by their actual value behavior (not by trusting header labels, which turned out to be unreliable in this export format), and using that to look at real idle behavior for the first time instead of relying on TunerStudio's live gauges alone.

01Log-by-Log Breakdown

Session-wide statistics computed across each full log. These pool every idle-qualifying sample in the file, so they run higher than the narrow steady-state windows cited in the final project report — that's expected; this view shows total session variability, not just the best segment.

tfire3.msl

First uploaded log. Established the MSL column-mapping methodology used for the rest of the project.

* On stall/restart counting Detected algorithmically as RPM dropping below 300 for a sustained period followed by a subsequent rise — a reasonable proxy for restart events, not a precise fault classifier. Treat as directionally accurate, not exact.
