Hover to inspect any point in the run — the tuner can use this to line up idle timing/AFR table cells against the coolant temperature and RPM that were actually seen at each stage of warm-up.
Zoomed into the key-on→running window (t=10s to t=35s). This is the section to send to whoever is chasing the cranking-voltage issue — the sag pattern is unmistakable.
Concrete numbers pulled from this log for adjusting the base tune — all from the fully-warmed portion (CLT > 85°C) unless noted.
| Channel | Value at warm idle | Notes |
|---|---|---|
| Actual idle RPM (last 80s, TPS<3%) | 963 ± 95 RPM | Still settling toward target; see convergence note below |
| Idle Target RPM | 906 RPM | From the CLT-based target curve, not yet modified this session |
| Idle actuator position (IAC/ETB duty) | 40.0–42.6% | Open-loop base duty, tight band |
| Ignition timing at idle | 13.3–15.7° (mean 13.9°) | Interpolated value at idle RPM/MAP, not a raw table cell |
| Injector duty cycle at idle | 1.5–5.5% (mean 2.3%) | |
| VE at idle | 49.9–54.4% (mean 53.7%) | Matches the "looks great" VE table finding from the tune review |
| MAP at idle | ≈27 kPa | |
| VBatt, running (post-start) | 14.2 V mean, 14.0–14.4 V range | Charging system healthy once running |
| Coolant warm-up | 32.1°C → 91.7°C over 22.7 min | 80°C at 7.5 min, 90°C at 15.3 min |
| Knock | None detected | Knock level, count, and retard all read zero for the entire log |
| Wideband O2 | Not connected | wb1isValid = 0 for the whole log — AFR/lambda channels are not usable yet |
| Peak RPM reached | 5,848 @ t=1231.4s | Clutch-in/neutral rev to redline area, 28% TPS, Vehicle Speed = 0 throughout, clean decay back down |
Idle: Closed loop active reads 0 for all 20,409 records, even though actual RPM sits below the closed-loop entry threshold (≈1207 RPM) for 99.7% of the idling samples — so the RPM-based entry condition is satisfied almost the entire time, yet closed loop never turns on. The open-loop CLT-based duty taper is still getting idle to converge (see trend below), so this isn't blocking anything today, but it's worth having the tuner check whatever other precondition (TPS-at-zero, "looks like running" state, etc.) is preventing entry, since closed-loop idle is the tool that will hold RPM tight against load once VTEC and A/C get added to the mix.First on-car test of the pending tune (Mark_LSVTEC_base_map_2.msq). Full cold start through 91.7°C warm idle, plus a clean off-load rev to 5,848 RPM. Same cranking-voltage-sag pattern as prior sessions, now with 3 distinct restart attempts logged.
