Software · Mercedes 7G-Tronic
One program for the gearbox controller: reading and clearing faults, coding variant editing, CFF file flashing, adaptations and live parameter view — for Mercedes 7G-Tronic (VGS2 and VGS3, the NAG2 family). Built in a workshop that programs these gearboxes every day.
Windows 10/11 · CANable 1.0 interface (candlelight / gs_usb) · UI in Polish, English, German · per-computer licence
What it does
Read and clear gearbox controller fault codes with built-in descriptions in Polish, English and German — no more searching forums for what 0218 means.
Read and write coding plus a variant editor with a code database (ratios, functions, CAN bits — e.g. shift paddles). You decode, change, save — Security Access is handled by the program.
Flashinging controller software from CFF (Caesar) files — separate, hardware-tested procedures for VGS2 and VGS3 (they differ in sequence and byte order). The CFF browser shows what's in the file before you flash anything.
Read and reset adaptations, ATF temperature and live parameters, gearbox operating statistics, controller identification data and FBS3 status.
Reading and writing the controller's EEPROM memory blocks — dump the contents to a file and write them back. Handy for repairs and transferring data.
Support for the gear selector module (ISM): identification, live data, and reading and clearing fault codes — tested on the module. PRND diagnostics next to the gearbox, in one program.
The program checks for new versions at start-up and downloads the installer — you don't have to track releases.
Before you buy
Windows 10/11. A USB-CAN interface CANable 1.0 (candlelight / gs_usb) — the same one that works with Smart CAN Tool.
Licence for jeden komputer with online transfer — deactivate it anytime and activate it on another computer. Activation with a key in the app after accepting the licence agreement; everything happens online.
Flashinging and coding are critical operations: the program watches the sequence, shows progress and stops on error. You make a coding backup with one button — always before writing.
Roadmap
Buy once and grow with us — updates are included in the licence. The features below will land as free updates for purchased versions (for an annual licence — during its validity period). This is our near-term roadmap; the order may change.
Unlocking the immobiliser in the module so the controller runs smoothly outside its original vehicle — paired with Seaside Customs hardware emulators.
Matching the body number to the target car straight from the program.
The final stage of development: resetting the controller to a „virgin" state and fully matching it to a new vehicle.
Already have a licence? You'll get each of these features as an update — at no extra cost (for an annual licence, during its validity period).
