AutoTuner SLAVE ProgrammerAutoTuner Slave is a professional ECU and TCU programmer designed for workshops and chiptuning specialists.
It enables reading and writing engine and transmission control units via OBD, BENCH and BOOT methods, as well as real-time parameter logging and DTC handling.
The Slave version works with encrypted files that are linked to the specific Master device indicated at the time of purchase. It is the solution for users who want to read and write control units but outsource file modification to their tuning provider.
The programmer supports OBD, BENCH and BOOT. It lets you choose the read and write method best suited to the specific control unit and vehicle design.
AutoTuner does not require recurring subscription fees to use the device. Updates are provided without any additional subscription.
The software shows the location of the ECU or OBD connector, the required accessories and how to make the connection. Clear photos make it easy to prepare the control unit correctly.

AutoTuner Slave is designed for working with engine control units (ECU) and transmission control units (TCU). The range of available operations depends on the specific control unit, vehicle and supported protocol.
The programmer can perform:

OBD
The OBD method enables communication with the control unit through the vehicle's factory diagnostic port. On supported vehicles, it does not require removing or opening the ECU.
It is the most convenient working method if the given control unit allows reading or writing via OBD.
BENCH
BENCH requires a direct connection to the control unit's connector, but without opening its housing. The ECU or TCU is usually removed from the vehicle and connected using the appropriate cables and adapters.
This method is used when programming via OBD is not available or when a different level of access to the control unit is required.
BOOT
BOOT requires opening the control unit housing and making a connection directly on the PCB. It allows working with ECUs that require hardware-level access to the memory or processor.

AutoTuner Slave reads and writes files in encrypted form. The Slave user does not edit the file themselves.
A typical process looks like this:
The Master is specified when purchasing the Slave device. Read files can be decrypted and modified by the Master entity linked to the device.
The AutoTuner software includes a technical support contact feature. Users can describe the problem directly from within the program and provide the information needed to analyse the case.
The programmer is ideal primarily for:
💡 workshops offering chiptuning;
💡 companies starting to work with ECUs and TCUs;
💡 shops working with an external file provider;
💡 car service centres expanding their offer with electronic tuning;
💡 workshops that don't need to edit maps themselves;
companies wishing to work in a Slave–Master system.
The Slave version is particularly practical when a workshop wants to be responsible for safely reading and writing the ECU, while leaving calibration development to a specialised Master.

Files read by the Slave version are encrypted and intended to be modified by the assigned Master.
Yes. The device can read and write supported engine ECUs and transmission TCUs.
The programmer supports OBD, BENCH and BOOT. The available method depends on the specific ECU or TCU.
The possibility of changing versions should be confirmed according to the current policies of the manufacturer or seller. Before buying, it's worth choosing the variant that suits your planned way of working with tuning files.
No. The Slave version is linked to the specific Master indicated at the time of purchase. Only that Master can decrypt and modify files coming from the given Slave device.
