TuneFI App

TuneFI has no buttons and no screen — the app is the interface. It connects over Bluetooth and everything happens on your phone: live dashboard, fuel maps, ride recording, firmware. No laptop, no cables.

Fuel maps, end to end

Read the current map off the device, trim any cell, write it back — over Bluetooth. A live crosshair shows exactly where the engine is on the grid. Import a shared map from the fuel maps page, export yours as JSON for the next person.

16×16 cells, RPM × throttle — the blue crosshair is the engine, right now

TuneFI app fuel map editor — the full 16×16 RPM × throttle grid with the live crosshair at idle

Your engine, live

RPM, throttle, fuel enrichment, injector pulse width, battery volts — big, live numbers while the engine runs. Widgets appear for whatever is connected: AFR when a wideband does, ECU temps and speed when the K-line does.

one packed binary link over BLE feeds the dash, the map, and the logger alike

TuneFI app dashboard live — 4796 RPM, 7% throttle, +4% fuel enrichment, injector pulse width in and out

Record & relive

Press REC before you ride. Sessions store full-rate data on your phone — charts with crosshairs, per-sensor toggles, exact runtimes. Export as CSV or JSON, and the file drops straight into Studio.

recordings never leave the phone until you export them

TuneFI app session charts — RPM and throttle time series from a recorded ride, with one-tap CSV export

Better over the air

New firmware installs from the phone over Bluetooth — no cables, no laptop. Every release is signed and the device refuses anything it can't verify. Stable and beta channels exist — the guide's advice stands: stay on stable.

RSA-PSS signatures with rollback protection

Also in the box

Corrections in one tap

Heatmaps and a correction grid for real tuning — apply the change to the device with one tap. Trim by cell, not by guesswork.

Air-fuel ratio, measured

Plug in a wideband and AFR joins the dashboard — digitally from a Spartan, or any analog unit with a simple two-point map.

The bike's own data

Coolant temp, intake pressure, speed, FI codes — read straight from the factory ECU over the dealer's diagnostic wire.

Your data stays yours

No accounts, no cloud, no analytics. The phone talks to the device over Bluetooth and that's it.
