## What is TuneFi?

TuneFi connects to your motorcycle's ECU via Bluetooth and gives you full control over engine tuning and telemetry — all from your phone.

REAL-TIME DASHBOARD
See live engine data at a glance: RPM, throttle position (TPS), air-fuel ratio (AFR), and temperatures. The dashboard streams data directly from the ECU over BLE with minimal latency.

DATA RECORDING
Record sensor readings during rides. Sessions are saved locally on your device with timestamps, so you can review and analyze your data offline. Browse past sessions and export data for external analysis.

FUEL MAP EDITOR
Read and write fuel maps directly over Bluetooth. Adjust individual cells in the fuel table to fine-tune your engine's air-fuel mixture across RPM and TPS breakpoints. Save multiple map configurations and load them on demand.

TPS CALIBRATION
Calibrate your throttle position sensor and configure TPS spoofing with RPM-based correction — all from the app.

OTA FIRMWARE UPDATES
Update your ECU firmware wirelessly over BLE. No cables or laptop needed — just connect and update.

PRIVACY FIRST
TuneFi stores all data locally on your device. No accounts, no cloud, no analytics, no data sharing. Your riding data stays yours.

Requirements:
- TuneFi PlanetKLX2 fuel controller with compatible firmware
- Bluetooth Low Energy support

## Version history (last 4 releases)

### 1.6.2 — 2026-10-26

Firmware 0.42 compatibility: wideband polling state now syncs from the device status key on firmware 0.42 and newer; the field fleet on older firmware keeps using the legacy wideband status command.

ECU diagnostics fixes: the ECU throttle position row shows a calibrated percentage instead of raw counts, and sensor rows backed by voltage signals now say volts instead of claiming %.

Spoof settings: throttle cap range matches the firmware 0.41 contract (0–99).

### 1.6.1 — 2026-10-21

Pairs with firmware 0.41 — new v9 live-data stream: richer sensor groups, injector-event recording with hardware-exact timing, and live data that no longer truncates mid-session. Recordings capture the raw stream losslessly for offline analysis.

Update gating: warns or blocks when firmware and app versions are incompatible, instead of silently misreading data.

Autotune: parses firmware 0.41.4 transient-gate (accelerator pump) events.

Fixes: the session loss flag no longer reports a false all-clear when the app was older than the firmware from the first packet; TPS display follows the device's own calibration and holds readings across packet gaps; connection stats no longer double-count successes; fuel-map live-sync fixes.

### 1.5.3 — 2026-10-14

Features now unlock in-app — enable them right from the device card (pairs with firmware 0.40.5 licensing).

Autotune is reworked for firmware 0.40: corrections arrive as live events while you ride, tuning has a one-switch auto mode, and fuel and ignition curves are edited as charts — drag to shape, tap a point for exact figures. A new 16×16 audit heatmap shows where the engine rode and which cells received corrections.

Also new: Target AFR table import/export, binary export of the audit grid, and fuel-map edits that auto-save with a save indicator.

Ride recordings now export the device's fuel map at stop, so the learned trajectory can be verified against reality. Exports also state session completeness and locate packet-loss windows.

Fixed: long-ride exports no longer run out of memory, map writes on small-Bluetooth-packet phones fail with clear messages instead of crashing, and icons render correctly in dark mode.

### 1.2.0 — 2026-10-13

No release notes.
