Convert CTZ to BIN

EFILive stores a tune in an encrypted, custom-compressed .ctz container. hptbin decodes it to a flat .bin — locked and unlocked files are both handled, both key modes are tried automatically, and the calibration is rebuilt byte-for-byte. Included in the hptbin app subscription.

Convert CTZ to BIN runs in the hptbin app

Questions

FAQ

What is a .ctz file?

It's EFILive's tune container — an encrypted, custom-compressed image of the ECU calibration. This tool reverses that back to a raw .bin.

Does it work on locked CTZ files?

Yes. The converter decodes both unlocked and locked CTZ files, using whichever key mode decompresses cleanly.

Where is my .ctz decoded?

Securely on our servers. The .ctz is decoded, the .bin sent back, and nothing is kept afterwards.

How is a conversion paid for?

This conversion runs in the hptbin Windows app. The app is free to install, and the conversion is covered by the Pro subscription with no per-file charge.
