LEGEND
Samples(EGO/AFR): EGO-effective frames / AFR weighted samples for this cell.
More samples = higher confidence in the recommended correction.
Confidence: HIGH (≥30 samples — trust the correction)
MED (10-29 — generally reliable)
LOW (1-9 samples — drive the operating range more and re-log to confirm)
EGO Trim: live closed-loop correction the ECU was applying when the cell was hit.
AFR Err: measured AFR minus target. Positive = LEAN (engine read too lean).

HOW TO READ THIS REPORT
-------------------------------------------------------------------------------------
Each row shows what the wideband measured (AFR Actual) and what the ECU's live
closed-loop trim was doing (EGO%) at that cell. When the two signals AGREE,
the tool follows them. When they DISAGREE, the tool follows EGO trim because:
- EGO integrates over more frames and is more robust than a small AFR average
- EGO is resistant to transient lean spikes (fuel-cut leak, AE smear)
- A few outlier AFR samples can skew the average on low-sample cells
The Driver column makes this explicit:
EGO ✓ = AFR and EGO pointed the same direction (or one was flat)
EGO ! = AFR and EGO pointed OPPOSITE directions — tool followed EGO
(for applied corrections, EGO drove the VE move; for OBSERVED cells,
EGO drove the tier classification even with no correction applied)
AFR = no EGO data on this cell, tool used AFR only
— = neither signal had meaningful direction (both flat / no data)
Cells with AFR data: 69
On target (|gap| ≤ 0.1): 4
Lean (gap > +0.1): 0
Rich (gap < -0.1): 65
Corrections applied where EGO & AFR agreed: 62
Corrections applied where EGO overrode AFR: 0 (marked "EGO !" below)
Weighted avg gap (by EGO samples): -0.593 AFR
Weighted avg |gap|: 0.595 AFR
Total EGO frames across cells: 2612
Sorted by |gap| descending — worst deviations first.

LEGEND
Gap = Actual - Target. Positive = LEAN, Negative = RICH.
Min/Max/σ: AFR distribution across the log for this cell.
Samples(EGO/AFR): EGO raw frames / AFR weighted samples.
* after sample count = AFR samples < 5 (average may not be reliable).
EGO%: ECU live closed-loop trim direction and magnitude.
Driver: signal that drove the correction (see header note above).
Status: how the tool classified this cell.
VE move: before → after applied (delta).

Apply the corrected MSQ to the car. 2. Drive in the operating regions listed above — both low-confidence cells and uncovered regions. 3. Capture a fresh log and send it back for the next tuning round. 4. If EGO authority was exhausted, widen authority before the next log.
