Tuners Guild® Tools
ECU tuning tools, built by calibrators.
Tuners Guild Tuning Tools is one portal for the tools we use in our own ECU work — now open in beta. Read what each tool does, or go straight in.
The Tools
Five tools. One portal.
Built for our own reverse-engineering work and opened to calibrators in beta. Read what each tool does, then open it in Tuning Tools.
Scrambler
Protect a tuned file from being copied or resold. Upload the original and the modified file; the engine obfuscates the calibration area so the file works on the car but cannot be read back into WinOLS® as a clean project.
About Scrambler →Ghidra Prep
Upload a full flash read. You get back a Ghidra project with the code already recovered: functions in place, calls that lead somewhere, map reads linked to the code that uses them. Import it and start reading the logic instead of fixing the setup.
About Ghidra Prep →RAM Address Finder
Upload a full flash read of a Bosch EDC17CP44 and get the CAN matrix of your firmware: every ID the ECU receives and sends, every frame field with its RAM variable, names where the open DBC knows them. DBC, CSV and JSON downloads.
About RAM Address Finder →DAMOS Generator
Upload a full flash read of a Bosch ECU and get its DAMOS: from our base when your software version is known, or transferred from the closest known version when it is close enough.
About DAMOS Generator →Maps Import
Converts a WinOLS CSV export into the .TUNERSGUILD format read by the Ghidra import script, so every map becomes a labelled, typed data item in your disassembly.
About Maps Import →Why
Built for our own work. Opened in beta.
These tools come out of the reverse-engineering work behind the Tuners Guild courses. We use them ourselves. The beta opens them to working calibrators while we extend ECU coverage and watch what people actually need from them.
How It Works
Three steps. One portal.
Open Tuning Tools
One portal for every tool: tools.tunersguild.com.
Sign in with your email
A code arrives by email. No password to remember.
Upload your file, pick a tool
The portal recognises the ECU and shows the tools that work with your file.
Forum
Talk to working calibrators. Open discussion.
Workflow tips, edge cases, bug reports — the Tuning Tools forum is where calibrators share what they actually do with these tools. One thread per tool, one community.

Tuning Tools is in beta. Supported ECUs and features change as we test — check the portal for the current state.
