EDITOR PRO — The professional hex comparator for ECU tuning

EDITOR PRO in action — Hex comparison live

What is EDITOR PRO?

EDITOR PRO is the online hex editor by Chip-Tools SRL, designed specifically for ECU tuning. Works directly in the browser, no installation needed: upload two .bin, .ori or .hex files (original and modified) and get a byte-by-byte comparison with automatic ECU detection, memory zones, maps, and checksum calculation.

What you can do with EDITOR PRO

  • 🧬 Compare two ECU dumps side-by-side
  • 🔬 Automatically identify the ECU from hex
  • 📍 Add markers and navigate through differences
  • 🛠️ PRO modules (credit-based): KM correction, IMMO Off, Radio Code, CRC fix
  • 📚 Integrated CT R&D recipes for the most common ECUs
  • 🌍 Interface in 5 languages (IT, EN, DE, ES, PL)

Same size ≠ same file: an important insight

Two .bin files with identical size (for example both 4096 KB) can still be completely different. Picture it this way: a 1-litre bottle filled to the brim, and a 1-litre bottle filled only halfway, have the same physical size — but the amount of water inside is not the same. The same is true for .bin files.

The classic mistake: OBD-read file flashed via bench

An example from workshop reality: you read an ECU via OBD. Result: a .bin file of, say, 4096 KB. Then you want to flash the same ECU via bench. What happens? The bench write routine expects all bytes, but OBD reading often provides only part of the data — the rest are FF or 00 placeholders. If this incomplete file gets flashed back: the ECU goes into bricked state — engine control lost, costly workshop damage.

With EDITOR PRO you see the difference in seconds

EDITOR PRO loads both files and runs a byte-by-byte comparison. Within seconds you recognise:

  • ✅ Which areas are identical
  • ⚠️ Which areas are different (FF/00 vs real data)
  • 🔍 The “present” vs “missing” zones

You instantly know: “Ah, this file is OBD-read, not suitable for bench flashing” — and you avoid the ECU brick.

Bonus: automatic recognition of different sizes

If you upload two files with different sizes (e.g. one 2 MB and one 4 MB from the same ECU), EDITOR PRO detects this automatically and suggests how to proceed: padding, offset alignment, subsection match. No manual calculation needed.

Who it's for

EDITOR PRO is a professional tool for tuners, ECU repair specialists, .bin file analysts and automotive technicians who work daily with ECU dumps.

How much does it cost?

EDITOR PRO is free for basic functions (comparison, identification, markers, recipes). PRO modules (KM correction, IMMO Off, Radio Code, CRC tools) require credits purchasable separately.
