Sample Datalog Analysis Report
One finding. One safe next step.
This is an illustrative report format, not a real customer result, vehicle-specific instruction, repair service, or emissions/safety certification.
UNSAFE TO CONTINUE PULLS
Measured lambda trends lean under boost
Example supported log — turbocharged setup under sustained boost (illustrative)
Primary Finding
Above 5100 RPM under sustained boost, measured lambda is leaner than commanded lambda.
Evidence Shown
Commanded lambda: 0.80. Measured lambda: 0.91-0.94. MAP: 185-202 kPa. RPM: 5100-6700.
One Next Step
Verify fuel pressure under lower load and capture a proof log with the same required channels.
Do Not Do Yet
Do not increase boost or ignition timing while the lean-under-load condition is unresolved.
Confidence: High in this example. Required channels are present, the pattern persists through a sustained load region, and a safety threshold is crossed.
Product boundary: MapMedic is a software tool that helps users review automotive datalog files and identify possible troubleshooting patterns. It does not modify vehicles, flash ECUs, sell tuning files, sell parts, provide emissions bypass/delete services, or perform mechanical repair work.
