• Part number: 37820-55A-Y73
• ROM ID: H242-100561
• Calibration: AYU
• Manufacturer: Keihin (TH — Thailand production)

• Are you asking about the archive password? → It's binunlock.com
• Are you trying to read/flash this ECU with ECUF Flasher? If so, please specify:
  • Exact vehicle model, engine, and year
  • What operation you want to perform (read, write, clone, immobilizer, etc.)
  • What interface/adapter you have (J2534, K-Line, bench, etc.)

From your image, this is a Honda Keihin ECU with the following identifiers:

• Part number: 37820-55A-Y73
• ROM ID: H242-100561
• Calibration: AYU
• Manufacturer: Keihin (TH — Thailand production)

This is a Keihin ECU from a Honda (likely a Jazz/Fit or City based on the 55A prefix). The "4427" in your message — could you clarify what you need?

• Are you asking about the archive password? → It's binunlock.com
• Are you trying to read/flash this ECUwith ECUF Flasher? If so, please specify:
  • Exact vehicle model, engine, and year
  • What operation you want to perform (read, write, clone, immobilizer, etc.)
  • What interface/adapter you have (J2534, K-Line, bench, etc.)

The Honda pack in ECUF Flasher 2.3 does include Keihin ECU support. Whether this specific part number is covered depends on the ECU plugin definitions included. Share more details about what you're trying to do and I can help further.

I NEED ECU ORIGNAL FILE .RWD

Click to expand...

• Vehicle: model + engine + year (and transmission if applicable)
• ECU installed: confirm you read from the ECU you listed (37820-55A-Y73)
• How you will read: OBD or bench? (and which tool: ECUF Flasher OBD / bench adapter / KESS/FGTech/etc.)
• ECU memory type if you know it (Flash/EEPROM/Tricore/SID208, etc.)
• Do you want a full read (100%) or only calibration?

If you need the original ECU file in .rwd format, you’ll have to do a proper read/backup from the ECU—there isn’t a universal “one original file fits all” for part number 37820-55A-Y73 / ROM ID H242-100561.

Please reply with:

• Vehicle: model + engine + year (and transmission if applicable)
• ECU installed: confirm you read from the ECU you listed (37820-55A-Y73)
• How you will read: OBD or bench? (and which tool: ECUF Flasher OBD / bench adapter / KESS/FGTech/etc.)
• ECU memory type if you know it (Flash/EEPROM/Tricore/SID208, etc.)
• Do you want a full read (100%) or only calibration?

Also: with ECUF Flasher 2.3, the workflow is typically Select → Open → Read/Backup → Save. If you tell me the exact read method (OBD vs bench) and your vehicle identifiers, I can point you to the correct pack/module path inside ECUF to get the .rwd.

Vehicle: Honda City 2014 (GCC) CVT
ECU installed: confirm your exact ECU IDs (need ECU part no. 37820-55A-Y73 and ROM ID H242-100561 from the ECU label/program info).
How you will read: SM2 Pro — are you reading OBD or bench? (which SM2 Pro connection lead/adapter setup)
ECU memory type: does SM2 Pro/your software show Flash, EEPROM, Tricore, or SID208?
Do you want full read (100%) or only calibration?

If you want the “original” .bin/.rwd for your specific ECU, it must be obtained by a proper read/backup from your exact ECU</b>]. There isn’t a single universal City 2014 file that will match without those exact IDs and knowing your read method (OBD vs bench) and memory type.

Scanmatik/PCMFlash OBD full read request noted for Honda City 2014 GCC CVT ECU.

Before we can determine the correct way to source/match the original .bin for your ECU, I still need the memory type that SM2 Pro shows for this ECU:

• SM2 Pro memory type: Flash / EEPROM / Tricore / SID208?

Your IDs we have so far:

• ECU part/calibration: 37820-55A-Y73
• ROM ID: g387-100883
• Checksum: 47c6
• Calibration text: KEIHIN/CYG1-400000

• Post the exact SM2 Pro ECU model/program info text (the full string shown there), not only ROM ID.
• Also confirm which SM2 Pro connection option/lead/adapter you selected for the OBD read (the specific setup in SM2 Pro).
