TunnerForge is a lightweight J2534 flashing utility — read, backup, and flash your ECU in minutes. For advanced tuning, our pro team handles the complex work.
Read your stock ECU file in minutes and save a backup. Always have a safe restore point before any changes.
Write tuned maps to your ECU quickly and reliably over J2534. Supports all major Japanese and European bike ECUs.
Restore your original factory map anytime with one click. No traces left behind — clean, safe, and reversible.
Read diagnostic trouble codes from the ECU and clear them after resolving issues. Know what your bike is telling you.
Works with SM2 Pro, Tactrix OpenPort 2.0, and any fully J2534-compliant Pass-Thru device. Also supports FTDI UART serial cables for older ECUs.
Under 150 MB. No bloat, no unnecessary features. Starts fast, flashes fast, stays out of your way.
Browse and download pre-built maps from our tuning team. Load a professionally tuned map and flash it with one click.
Master licenses can create encrypted, protected tune files with optional expiration dates. Slave users (or other Masters) can flash them but cannot view or edit the data inside.
Master-generated files are fully encrypted. Tuners can distribute tunes knowing their work is safe — no one can extract maps, copy parameters, or reverse-engineer the calibration.
Set an expiration date on any protected tune file. Ideal for dyno shops offering limited-time maps, race teams sharing setups for a season, or demo tunes that expire after testing.
Want a custom map? Our DirectTune team builds one for your setup. You receive the encrypted file and flash it yourself with TunnerForge.
Clean, straightforward UI designed to get the job done. No steep learning curve — if you can plug in a cable, you can flash.
TunnerForge supports J2534 Pass-Thru (SAE J2534-1 / ISO 22900) and FTDI UART serial connections. No proprietary hardware required.
J2534 — original SM2 Pro and quality clones. Our most tested and recommended interface.
J2534 — Tactrix OpenPort 2.0. Reliable, widely available, battle-tested by the tuning community.
Any J2534 Pass-Thru interface that fully complies with the SAE standard will work. No vendor lock-in.
Serial-based ECUs via FTDI chipsets (FT232RL/FT232H). Common on older bikes and certain brands.
