Scrambler · Tuning File Protection
The car runs. The thief gets chaos.
Your file still flashes and runs in the target ECU — but anyone who copies, edits, or resells it finds nothing they can use. The only tool of its kind. 5 files free, no card.
The Problem
You calibrate. They copy.
Every file you send to a client is a file that can be stolen, duplicated, and resold at half your price. The market has no solution. Until now.
Your files walk out the door
You spend hours creating a precise calibration. The client takes the file to a forum, gives it to a friend, or a competitor reads it from the ECU. Your work becomes someone else’s product.
Copied files undercut your price
A reseller takes your calibration, charges half the price, and competes with you using your own work. You lose the repeat client. You lose the margin.
No tool exists to stop this
Some tuners try custom obfuscation scripts. Most just accept the loss. Nobody has built a professional solution — because vendors sell to file resellers, not to you.
Open it. Edit it. There’s nothing left to read.
The protected file flashes and runs in the target ECU exactly as you built it. But its internal structure is scrambled into chaos — no maps, no logic, no order anyone can follow. A thief can open it, try to edit it, try to copy it — and make sense of none of it. Your calibration still works. Your know-how stays yours.
How It Works
Three steps. Thirty seconds.
Upload your file
Drop your finished calibration into Scrambler. Bosch MG1, MD1, EDC17 and MED9 supported today — MED17 and EDC16 coming next.
Scrambler protects it
Scrambler rewrites the file’s internal structure. It stays fully functional in the ECU, but its maps and logic can no longer be read, edited, or reverse-engineered for resale.
Send to your client
Download the protected file. Flash it to the ECU as usual. Your client gets the calibration. Nobody else can use it.
Your File Is Safe
Handing your file to a tool? Here’s why it’s safe.
It’s a fair question for any tuner: why upload your most valuable file to someone else’s tool? Three reasons.
We keep only the scrambled version
Scrambler stores only the protected file — the same unreadable chaos a thief would get. Your original working file isn’t kept. Even we can’t reconstruct your calibration from it.
Built by a working tuner, not a startup
Scrambler comes from Thomas — a reverse engineer who trains tuners worldwide. He has no reason to copy a file: he teaches people to build them, and can build any solution himself. This isn’t a faceless platform mining your work.

Questions
Frequently asked.
Scrambler rewrites the internal structure of your calibration file into chaos. The file still flashes and runs in the target ECU exactly as you built it — but its maps and logic can no longer be read, edited, copied, or reverse-engineered for resale. It works; it just can’t be reused.

We keep only the protected (scrambled) version — so you can re-download it anytime — and that version is unreadable to everyone, including us. Your original working file isn’t stored. Scrambler is built by Thomas, a working reverse engineer with no reason to copy anyone’s file.
Scrambler is free to try with 5 files per email. Tuners Guild students earn more — completing courses adds protected-file credits to your balance, and reaching Ghidra Mastery unlocks the top tier. Curious how it works? Just ask, or start below and the tool shows your balance.
Yes. For tuning shops and file services with high volume we offer a Business license sized to your throughput. Contact [email protected].
No. Scrambler is the only tool on the market for calibration file protection. Tuners either accept the risk of file copying or build custom scripts that rarely work. Scrambler solves this once.
There’s no password to crack. The file’s internal logic is scrambled, so even fully opened and editable, there’s nothing coherent left to copy or reverse-engineer. It only makes sense to the target ECU.
