wb1isValid = 0 for all 19,608 records), and idle closed-loop has still never activated.Hover to inspect any point in the run. Coolant (blue dashed) climbs from 86.9°F cold to 195.1°F peak; RPM (red) decays from ~1,400 warm-up to ~975 fully warm.
Numbers pulled from the fully-warmed portion (CLT > 176°F, TPS < 2%, 400–2000 RPM) unless noted.
| Channel | Value at warm idle | Notes |
|---|---|---|
| Actual idle RPM (CLT>176°F, TPS<2%) | 976 ± 68 RPM | Tighter than Day 8 tail (963 ± 95) — idle stability improving session to session |
| Idle Target RPM | 906 RPM mean | CLT-based target curve unchanged |
| Ignition timing at idle | 14.6° mean, 25.0° max | Timing: ignition channel, includes all corrections |
| Injector duty cycle at idle | 2.1% mean, 1.5–6.5% range | Low and clean; no enrichment artifacts |
| VE at idle | 53.7% mean, 51.1–78.7% range | Consistent with Day 8 (53.7%) |
| MAP at idle | ≈30.4 kPa mean | Slightly lower vacuum than Day 8 (≈27 kPa) — expect minor variation cold vs. warm |
| VBatt, running (post-start) | 14.204 V mean, 13.843–14.343 V range | Charging system healthy throughout |
| IAT | 87.3°F start → 158.4°F peak, 149.4°F end | Heat-soak rising as expected through the run |
| Coolant warm-up | 86.9°F → 195.1°F over 21.8 min | 176°F at 5.7 min; peak 195.1°F consistent with Day 8 (197.1°F) |
| Knock | None detected | Knock count, level, and retard all read zero for all 19,608 records |
| Wideband O2 | Not connected | wb1isValid = 0 & wb1fwUnsupported = 1 for the entire log |
| Peak RPM reached | 6,231 @ t=1145.5s | Off-load rev, 17.8% TPS, no VSS signal; clean decay back to idle |
Idle: Closed loop active = 0 for all 19,608 records, same as Day 8. RPM is within range for entry the entire warm portion, so the RPM precondition is satisfied — something else (TPS state machine, “running” flag, or a dedicated CL-enable condition) is blocking engagement. Open-loop taper is doing the convergence job in the meantime, but closed-loop idle is required before adding VTEC and A/C loads.Cold-start idle run. Full warm-up from 86.9°F, no issues, clean rev to 6,231 RPM. No cranking problems in this session — single-attempt start. Charging healthy throughout.
