What is an AutoTuner ECU tuning tool?

AutoTuner is a professional ECU and TCU programming tool used to read and write engine and gearbox control units. It supports OBD, Bench and Boot programming methods on thousands of vehicles, with guided instructions and built-in datalogging.

What is the difference between AutoTuner Master and Slave?

An AutoTuner Master produces unencrypted files — you can edit them yourself with compatible calibration software or send them to any tuning file provider. An AutoTuner Slave reads and writes encrypted files that are processed by the Master or file provider the Slave is linked to.

Does AutoTuner have an annual subscription?

No. AutoTuner does not require a mandatory annual subscription — software updates are included with the tool.

Can AutoTuner read and write ECUs and TCUs?

Yes. AutoTuner reads and writes both engine control units (ECU) and transmission control units (TCU), subject to protocol coverage for the specific unit.

Does AutoTuner support OBD, Bench and Boot?

Yes, all three methods are supported — but not every ECU supports every method. Coverage depends on the specific control unit and protocol; the software tells you which method applies to each vehicle.

Can I use Regal Tuning files with an AutoTuner Master?

Yes. Read the original file with your AutoTuner Master and submit it through the Regal Tuning file portal — our calibrators return a professionally developed tuning file. You remain free to use any file provider you choose.

Can an AutoTuner Master use another tuning file provider?

Absolutely. File independence is the point of a Master tool — you can edit files yourself with compatible software or work with any tuning file provider. Regal Tuning is one option, never a requirement.

Can an AutoTuner Slave be upgraded to Master?

Master and Slave are different licence configurations. If you think you may need Master-level independence later, talk to us before purchasing and we'll recommend the right route.

Can an AutoTuner Slave change Master?

A Slave is licensed to the Master it is linked to. Changing to a different Master requires the current Master provider to release the link — contact us and we will advise on the process for your tool.

Does AutoTuner include tuning or file editing software?

No. AutoTuner reads and writes ECU/TCU data, but dedicated calibration editing software is a separate product and is not included with the tool.

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.

View AutoTuner Master

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.
