Log2Tune
Log your wideband. Correct your VE table. Flash the J3.
A free Windows tuning suite for Speed Density Falcons on the factory EEC-V, EA through AU, and L2T Logger, a live OBD-II dash for your phone.
Download for Windows
Android app coming soon
A real drive on Jay's AU Turbo, replayed in Log Analysis, next to L2T Logger on Android.
From a drive to a better tune
Log2Tune logs real air-fuel ratio from your wideband, works out where the tune is rich or lean, and corrects the volumetric efficiency table to hit your AFR targets.
- Pick a car profileA new profile runs the setup wizard, which can generate physics-based starting VE and spark tables.
- DriveIdle, cruise and boost. Live Tune corrects the table as you go, or log now and process the drive later.
- Review the correctionsColour-coded deltas cell by cell, with playback to scrub through the drive.
- Flash the J3Write the corrected BIN to the chip without leaving the app. Every write is verified.
- RepeatThe learning database keeps per-cell history between drives and fills in cells the last one missed.
What you need
| Parameter | Value |
|---|---|
| CAR | EA through AU Falcon on the factory EEC-V, NA or forced induction |
| STRATEGY | Speed Density (MAP sensor based) |
| WIDEBAND | TechEdge 2J9 over serial, with MAP, TPS, RPM and VSS on its inputs |
| FLASH | TI Performance J3 chip at the PCM's J3 port |
| TUNE | An XDF definition and the matching BIN |
| ECU DATA | ELM327, WiFi or serial (optional, monitoring only) |
| PC | Windows 10 or 11, 64-bit |
Not for BA/BF ECUs, MAF strategies, cars without a wideband, or engines with vacuum leaks or mechanical problems.
Your XDF and BIN, table by table
- Tables, constants, functions, flags and patches open as floating windows on a workspace
- Cell editing, fill and scale, compare against the original, undo and redo
- 3D surface view, with edits syncing straight back to the table
- The J3 programmer lives here: connect, read, write and verify
Process a drive after the fact
- Loads native Log2Tune logs, TechEdge WinLog logs and complete .l2t session files
- Processing runs the Auto Tuning engine and colours the VE table by the change applied to each cell
- Playback replays the drive through the gauges, charts and table crosshair, with variable speed and scrubbing
- Prefer hands-on? Correct cells yourself straight from playback
Correct the table while you drive
- The wideband streams live and every sample runs through the same Auto Tuning engine
- Corrections land on the VE table in real time and are written to the BIN when the session stops
- Every session records itself as a .l2t you can replay and reprocess later
- Live wideband sensor health: heater drive, cell resistance and lambda
The learning database
- Coverage, correction effectiveness and per-zone status across every drive
- Heat maps and a detailed per-cell report, with export
- Each car profile keeps its own database
Everything lives in the car profile
- Engine and injector specs, with tuning presets and a built-in injector slope calculator
- AFR targets, zone thresholds, correction and stability parameters
- Sensor calibrations, units, gauge ranges and table display options
Tools for going deeper
- XDF definition editor with live previews against the loaded BIN
- ELM327 bus sniffer
- PID Maker for discovering and defining custom ECU PIDs
L2T Logger
Real-time OBD-II dashboard and logger for Android
- Build your own dash. Dials, bars, charts and numbers across as many pages as you like.
- WiFi or Bluetooth. Connects to your OBD-II adapter and remembers it.
- Record sessions. Logging carries on with the screen off. Export when you're ready.
- Alarms. Warning and danger rules, like lean under boost or over-rev.
- PID Maker. Define your own channels when the standard ones aren't enough.
- Nothing leaves your phone. No account, no analytics, no tracking.
Log2Tune for Windows
