Scrambler · Calibration File Protection
You build the calibration. Someone else sells it.
Scrambler is the only tool on the market that protects your tuning files from unauthorized copying and resale. 10 files free. No credit 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.
Your calibration is your intellectual property. Scrambler puts a lock on it.
The protected file works in the target ECU exactly as before. But it cannot be opened, edited, reproduced, or resold by anyone. The lock is invisible to the client — and permanent to the thief.
How It Works
Three steps. Thirty seconds.
Upload your file
Drop your calibration file into Scrambler. Any ECU format — Bosch, Siemens, Delphi, Continental.
Scrambler protects it
Server-side obfuscation. The file remains fully functional but cannot be edited, reproduced, 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 does.
The Math
Scrambler is included with Diesel Practice.
Diesel Practice costs €1,250. It includes Scrambler with 50 protected files per month (resets on the 1st). At €10 retail value per file, that’s €500 per month in tool value covered.
The course pays back in ~75 days from Scrambler savings alone — and that’s just one of the values you get.
Same math for Gasoline Practice (€1,220 → ~73 days). Beyond the tool: full diesel/gasoline calibration skill set, community access, and lifetime updates.
Two licenses to fit your scale
Individual or Business.
Most practicing tuners ship around 50 files per month — the Individual plan covers that with the course. File services and multi-tuner shops need more — that’s a Business license.

Questions
Frequently asked.
Scrambler obfuscates your calibration file so it remains executable only in the target ECU but cannot be reproduced, edited, or resold by third parties. The file works — it just can’t be stolen.
Scrambler works at the file level, not the architecture level. It supports all major ECU file formats — Bosch, Siemens, Delphi, Continental, and more. If you can flash it, Scrambler can protect it.
You’ll see an invitation to enroll in Diesel Practice or Gasoline Practice. Course enrollment includes 50 protected files per month with monthly reset on the 1st — plus the calibration skills to create better files worth protecting.
For tuning shops and high-volume operations (50+ files/month), we offer a Business license tailored to your throughput. Contact admin@tunersguild.com — pricing starts from €299/month.
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.
The protection is server-side obfuscation. The file is designed to be unreadable for editing or reproduction while remaining fully functional in the target ECU. It is not a simple password or checksum.
