SELF-SERVICE · CHICAGO, IL

A manual, messenger-based tuning service for trucks and cars rebuilt as a self-service platform: pick the machine, upload the encrypted firmware file, pay in credits, download the modified file. Rollback in one tap, and a failed order costs nothing.

01 · PICK THE MACHINE

Truck or car, by model and ECU.

The catalogue knows which control unit sits in which engine, and which patches exist for it.

02 · UPLOAD THE FILE

The encrypted firmware file goes straight to storage.

It never passes through the server. The order is priced before anything is touched.

03 · PAY IN CREDITS

Internal credits, no card at the roadside.

Top up once, spend per job. Every order stays in the account history.

04 · ROLLBACK READY

The original file is kept.

One tap restores it. A failed order is refunded on its own. No ticket, no messenger.

CASE 01 · ECU FIRMWARE PLATFORM · LIVECASE 01 · LIVE

Firmware, delivered without a human in the loop.

WHILE IT DRIVES

The patch rides along.

No workshop visit. The ECU is read, patched and verified on the move.

Nothing left to do by hand.
