This was a startup/idle log with only a brief rev to 820 RPM and 4.4% throttle—not a tuning pull. The main issue is a large learned lean correction on both banks, so verify unmetered air, MAF calibration, injector data, and fuel pressure before changing the tune.

StreetTunedAI — Log Review long drive.csv Platform: LS · Vehicle: 2005 chevy silverado 6.0 ls Generated 7/18/2026, 8:33:26 PM · Uploaded 7/18/2026, 7:17:46 PM Part-throttle / cruise log · Channels: 19 · Rows: 14009 Wideband present KR present MAF missing Action First — Stop driving until resolved Knock retard under load — peak 5.71° occurring at real load (MAP >= 70 kPa or pedal/throttle >= 40%, RPM >= 1500). Do not advance timing. Check fuel quality, IAT, and the timing table. Note: 362 of 1241 knock events were at low load and may be noise — focus on the under-load events. Confirm this is the live per-event Knock Retard, not a stored/total knock value, before pulling timing. STREETTUNEDAI REVIEW Bottom line HARD STOP — this log shows knock retard under load. Peak KR was 5.71° at real load, so do not advance timing or make power-adding changes from this log. This was a part-throttle / cruise log, not a WOT/PE pull, so boost control, PE fueling, and WOT safety cannot be evaluated yet. What the data shows Log parsed cleanly: 14009 rows, 19 recognized review channels, boosted LS/P59 setup, speed-density context. This was part-throttle / cruise: Peak MAP: 112 kPa Peak RPM: 3684.5 Peak throttle: 48.2% WOT samples: 0 Analyzer found no WOT / PE hit, so PE fueling cannot be judged. Fuel trims look calm during the logged driving: Bank 1 STFT avg: -0.22% Bank 2 STFT avg: 0.67% Bank 1 LTFT avg: -0.08% Bank 2 LTFT avg: 0.53% LTFTs were active, with average learned correction at 0.23%, so there is no large learned correction showing in this part-throttle data. Knock is the issue: Idle/low range: Avg KR: 0.45° Max KR: 0.88° 58 rows MAP range: 61–63 kPa Longest event: 3651 ms This is mild and could be noise/mechanical/sensor-related. 1500–2000 rpm range: Avg KR: 1.17° Max KR: 5.71° 1595 rows MAP range: 50–91 kPa StreetTunedAI · Log Review Page 1 of 6

Longest event: 16793 ms Repeated in 12 of 19 qualifying pulls This is the part that matters. It repeated under load, so it cannot be dismissed as one random blip. The analyzer also noted that 362 of 1241 knock events were at low load, which may be noise, but the under-load KR is still the hard stop. Air/load snapshot: Peak MAP: 112 kPa Peak RPM: 3684.5 Peak IAT: 100.4°F No boost event was captured, so wastegate control and boost tracking cannot be evaluated from this log. What I’d verify first Before touching the tune hard, verify the KR source: Confirm this is the live per-event Knock Retard channel, not a stored/total knock value. Check fuel quality and the actual conditions during the KR. Review IAT-related behavior, especially since your notes mention excluding rows where IAT is pegged at 284°F for meth failsafe testing. This log’s peak IAT reported by the analyzer was 100.4°F, but the general point still matters: don’t judge fuel/spark from failsafe-forced rows. Check for false knock sources: Exhaust contact Loose brackets Downpipe/crossover contact Converter/trans noise Knock sensor mounting/wiring Because the KR repeated in the 1500–2000 rpm area across 12 of 19 qualifying pulls, treat it seriously until proven false. Also, do not use this log to make a WOT fueling call. The wideband channel was present, but there was no WOT data, so measured WOT AFR was not evaluated. What to change first First edit path from the analysis: Pull 1–2° timing in the exact 1500–2000 rpm cells where KR occurred. Manually blend/smooth around those areas. Before making the timing edit, verify HP Tuners Interpolate is OFF unless you intentionally want it spreading the change into neighboring cells. Relog and confirm the KR is actually reduced/resolved before changing anything else. No PE fuel edit yet. The analyzer specifically says WOT/PE data was not captured. Leave alone for now Do not touch these yet: PE fueling — no WOT/PE data in this log. WOT spark — no clean WOT pull, and KR needs to be resolved/verified first. Boost target changes — no boost event was captured, so boost tracking cannot be evaluated. Injector data — do not change it without confirming fuel pressure and wideband behavior first. Virtual VE / SD table — analyzer says not to touch it from this log alone. Idle airflow and throttle follower/cracker settings — this was not a startup/idle diagnostic log. Misfire diagnostics — not enough here to make that call. Confidence StreetTunedAI · Log Review Page 2 of 6

Channel identification: high — 19 channels matched cleanly. Fuel trim read: high — STFT and LTFT were both present, and LTFT had learned. Knock read: high — knock events were classified against load channels. Startup: not evaluated — no start or idle section. WOT: not evaluated — no WOT / power-enrichment data in this log. Next log Do two separate logs. Part-throttle VE/SD cleanup log: Fully warmed up. 10–15 minutes of smooth driving. No WOT. Cruise in multiple gears at steady throttle. Use STFT/LTFT averages by RPM and MAP load cell for VE correction work. Since this is SD, MAP and RPM are the main load axes. WOT validation log after part-throttle cleanup: Wideband required. Clean full-throttle run in an appropriate gear, starting at a safe engine speed. Log: Commanded EQ/lambda Wideband AFR/lambda KR MAP Injector pulse width Timing Fuel pressure MAF Hz is secondary on SD; MAP and RPM matter most. What I couldn’t see No WOT / PE data was captured, so PE fueling, WOT AFR, WOT spark behavior, and full-load safety cannot be evaluated. No boost event was captured, so boost tracking and wastegate control cannot be evaluated. Torque management cannot be confirmed because the needed TM channels were not in this log. No TM intervention was detected in the channels that were logged, but that does not prove TM was absent. No MAF channel was logged. For this SD setup, MAF is not required, but MAF-based corrections are not available from this log. BIGGEST RISKS — HARD STOPS Knock retard under load — peak 5.71° occurring at real load (MAP >= 70 kPa or pedal/throttle >= 40%, RPM >= 1500). Do not advance timing. Check fuel quality, IAT, and the timing table. Note: 362 of 1241 knock events were at low load and may be noise — focus on the under-load events. Confirm this is the live per-event Knock Retard, not a stored/total knock value, before pulling timing.

KR by RPM range: idle/low: avg 0.45°, max 0.88° (58 rows, MAP 61–63 kPa, longest event 3651 ms) — mild 1500–2000 rpm: avg 1.17°, max 5.71° (1595 rows, MAP 50–91 kPa, longest event 16793 ms — repeated in 12 of 19 qualifying pulls) — moderate Moderate to severe KR in: 1500–2000 rpm. Do not add timing. Pull 1–2° in the exact cell(s) where KR occurred, then manually smooth the surrounding cells yourself — do not rely on HP Tuners Interpolate to do that blending automatically. Before making any edit, verify Interpolate is OFF unless you intentionally want it spreading the change into neighboring cells. Relog and confirm. Possible causes include timing too aggressive for the fuel and conditions, fuel delivery variation, IAT, or false knock from a loose sensor — review knock sensor mounting and wiring before assuming the tune needs a large correction. The following ranges showed KR on multiple loaded events: 1500–2000 rpm (12 of 19 qualifying pulls, longest event 16793 ms). A repeating pattern across multiple pulls is a stronger indication of a consistent condition than a single spike, but the cause still needs to be confirmed — do not assume it is the tune without ruling out fuel quality, IAT, false knock, and sensor issues first.

Fully warmed up. 10–15 minutes of smooth driving. No WOT. Let the car cruise in multiple gears at steady throttle. The primary correction target is the VE (Volumetric Efficiency) table, not the MAF table. STFT/LTFT averages by RPM and MAP load cell are the key inputs for VE corrections. WOT validation log (after part-throttle cleanup): Wideband required. Conduct any high-load or full-throttle testing safely and legally. Leave traction control on unless disabling it is explicitly appropriate and safe for your vehicle and environment. Record a clean full-throttle run in an appropriate gear starting at a safe engine speed. Log: commanded EQ/lambda, wideband AFR/lambda, KR, MAP, injector pulse width, timing, and fuel pressure. MAF Hz is secondary on SD — MAP and RPM are the primary load axes. BOTTOM LINE This calibration shows at least one hard-stop condition that should be resolved before further driving. See the Biggest Risks section above. Follow the Next Log Plan above to continue narrowing the tune. This review is supported-interpretation-only. A scan log alone cannot prove the calibration is safe; verify all values in HP Tuners before applying. StreetTunedAI · Log Review Page 6 of 6 Conservative analysis only. Verify all values in HP Tuners before applying. Numeric edits require valid wideband, KR, and load data; do not apply WOT changes from a partial or unverified log.
