Real-World Impact

OBD Validation & DFC Analysis

Challenge: Manual OBD-II validation took 8-12 hours per vehicle with high error rates.

Solution: DFCAgent + IUPRAgent auto-process MDF/MF4, correlate DTCs, compute IUPR, and generate evidence-backed reports.

Result: Reports in under 3 minutes at 99.7% accuracy. 3 critical compliance issues caught automatically.

95% Time Reduction 99.7% Accuracy OBD-II / IUPR

OBD VALIDATION

MISFIRE

HUNTING DETECTED

Advanced Misfire Detection

Challenge: Intermittent misfires were missed by standard OBD-II codes (only 60-70% detection).

Solution: MisfireAgent uses 9 algorithms (CSVA, FFT, ML, statistical, correlation) to detect subtle patterns.

Result: Detection accuracy 98.5%, 12 intermittent misfires found; full severity timelines for calibration fixes.

98.5% Accuracy 9 Algorithms ML + CSVA
