TGFlash is the reliable car ECU & TCU flashing software with affordable pricing and practical functionality.

Key features

Standard, Master and Slave versions available for all tuner capabilities and needs. Standard and Master versions must be purchased with at least one of the available protocols. The standard version provides all the functions required to read and write open binaries from ECUs using the purchased protocols.
The master version differs from the standard version in that slave versions can be connected. Slave files can be coded by the master for the number of writes and / or the expiration of time with unauthorized reuse protection. Thus, the master version is suitable for companies who want to protect their files against unauthorized use.
Slave versions are purchased from the Master and the annual subscription payment can be sent directly to us. The slave user has access to all protocols that his master has (as long as M & S Sub is valid). The slave version stores read files that can only be decoded by the associated master. In addition, master and slave versions have messenger capabilities (with file attachments if needed) for convenient communication and sharing files. Migration of the slave license from one master to another is not allowed.

All TGFlash protocols automatically adjust checksums and signatures when writing.

You will receive the software download link and the activation key immediately after your payment by e-mail. No USB dongle required, just a license key that connects to your computer during installation. No shipping, no waiting, everything online. You can only use the license key on one computer and only with one instance of the TGFlash software.
