Genuine AutoTuner Equipment

AutoTuner ECU & TCU Tuning Tools

AutoTuner is a professional ECU and TCU programming tool offering OBD, Bench and Boot methods — available as a Master tool for full file independence, or as a Slave linked to your chosen file provider.

Why AutoTuner

A professional tool, built for daily tuning work

OBD, Bench & Boot

ECU and TCU reading and writing through the diagnostic port, on the bench, or in boot mode — depending on the supported protocol.

Automatic Checksum Correction

Checksums are corrected automatically during the writing process on supported families.

Real-Time Datalogging

Live engine data logging built into the tool for calibration development and verification.

Guided Instructions

Step-by-step software guidance and connection instructions for each supported vehicle.

Free Software Updates

Ongoing software and protocol updates are included with the tool.

No Annual Subscription

AutoTuner operates without a mandatory annual AutoTuner subscription fee.

Master vs Slave

Choose the licence that fits your business

Independence

AutoTuner Master

AutoTuner Master reads ECUs and TCUs and produces unencrypted files. Modify them yourself using compatible binary editing software, or send them to a tuning file provider of your choice — the file is yours.

Master is intended for professional tuners who want independence and full control over their tuning files.

Supported

AutoTuner Slave

AutoTuner Slave reads and writes encrypted files that are processed by the Master — the tuning file provider the Slave is linked to.

This suits workshops and tuners who want professionally developed calibration files without developing the files themselves.

Programming Methods

OBD, Bench & Boot explained

Three ways to reach the control unit. Which method applies depends on the specific ECU or TCU — not every unit supports every method.

01

OBD

Programming through the vehicle's diagnostic connection, where the ECU or TCU protocol supports it. The fastest method for day-to-day tuning work.

02

Bench

Direct connection to the ECU or TCU on the bench, outside the vehicle, without opening the unit — where the applicable protocol supports it.

03

Boot

Direct ECU access used for applicable control units and protocols, typically for recovery or units not covered by OBD or Bench methods.

Vehicle Compatibility

AutoTuner Vehicle Compatibility

Check whether your vehicle, ECU or TCU is supported by AutoTuner — search by make, model, engine or ECU and see the available connection methods (OBD, Bench, Boot). Compatibility data comes from the official AutoTuner vehicle database; exact coverage depends on the control unit and your Master or Slave software.
