KTuner CSV Diagnosis
Upload a KTuner datalog and get an informational troubleshooting report.
MapMedic is strongest on clean Honda and Acura KTuner CSV logs. It checks fuel state, trims, boost AFR, timing behavior, knock evidence, temperature, voltage, and whether a customer-side calibration decision has enough supporting evidence.
Checkout opens from the MapMedic app. Sign in by email, upload a supported KTuner CSV, and choose a diagnosis-credit plan.
KTuner-specific strengths
- Recognizes KTuner channel naming and common fuel-state labels.
- Separates closed-loop trim diagnosis from open-loop boost evidence.
- Flags dirty data before fuel or ignition advice is allowed.
- Can produce constrained KTuner table-path guidance only when the log earns it.
Common KTuner problems
- OL-Drive entering in the wrong area.
- Boost AFR rich or lean under real load.
- Suspicious low-load knock or sensor/circuit blockers.
- High ECT, weak voltage, short logs, and missing core channels.
Best upload format
Export the datalog as CSV. Include RPM, MAP, TPS or pedal, lambda or AFR, coolant temperature, fuel state if available, timing, voltage, and knock channels when possible.
What it will not do
It will not invent a fuel table correction from weak evidence, work around an unresolved sensor fault, or treat a short idle log like a full boost proof log.
