ECU Datalog Analyzer

Stop guessing from a CSV. Get one safe next step from your datalog.

MapMedic reads supported ECU log exports and turns them into a practical diagnosis: safety status, root-cause evidence, what not to touch yet, and what to prove on the next log.

What MapMedic checks

Fuel trims, lambda/AFR, open-loop and closed-loop behavior.
Boost AFR, injector duty, temperature, voltage, timing pull, and knock evidence.
Import confidence, missing channels, bad units, and unsupported binary formats.
Whether the next move is professional inspection, proof logging, additional evidence, or stop-driving.

Supported uploads

CSV, Excel, JSON, UTF-16 text, and other clean text exports can work when the core channels map cleanly. Proprietary binary logs usually need to be exported as CSV first.

Exact table-cell work orders remain evidence gated. Generic logs get bounded diagnosis without invented ECU table paths.

Built for stuck datalog reviews

Use it when a car is rich in cruise, lean in boost, stuck in open-loop warmup, showing suspicious knock activity, running hot, or producing messy log evidence that needs triage before another pull.

Safety first

MapMedic does not flash ECUs or bypass emissions systems. It explains what the log proves, what it does not prove, and what proof log should come next.
