Need 1 more identifier to match the correct “original” full read for your ECU:

  • 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).

ecu SH7058

SH7058 alone isn’t the exact full “model/program info” string SM2 Pro shows.

Paste the complete ECU model/program info text exactly as displayed in SM2 Pro (the whole line/string, not only the “SH7058” part).

Also confirm which specific SM2 Pro OBD connection option/lead/adapter setup you used for the read (the exact setup name/option in SM2 Pro).

Here's a summary of everything collected for your ECU:

  • Vehicle: Honda City 2014 GCC, CVT
  • ECU part number: 37820-55A-Y73
  • ROM ID: G387-100883
  • MCU: Renesas SH7058 (Keihin)
  • Calibration: KEIHIN/CYG1-400000
  • Checksum: 47C6
  • File size: 524288 bytes (512 KB)
  • Sticker codes: YU, AYU
  • Read tool: Scanmatik / PCMFlash, OBD, Flash memory

Important points:

1) If you already did a successful full OBD read via PCMFlash (512 KB), that is your original file — save it as your backup. That's the "full bin."

2) If you're asking because the ECU is bricked or corrupted and you need a donor original to restore, you need a .bin from the exact same calibration ID (37820-55A-Y73) and ideally the same ROM ID (G387-100883). That can only come from another unit with matching IDs or a Honda dealer calibration database — it can't be generated here.

3) If you have a read but suspect it's bad — post the file or a screenshot of the hex header (first 256 bytes) and we can check if the read looks valid (correct header, no blank areas, checksum match).

What exactly is your situation?
  • Did you already read the ECU successfully and want to verify the file?
  • Is the ECU bricked/not starting and you need a clean file to flash back?
  • Are you looking for a stock file to compare against a modified one?

Without knowing this, nobody can help further.

IF YOU HAVE SEND ME PLEASE

IF YOU HAVE SEND ME PLEASE

You can’t just “send the full bin” for your ECU unless it matches your exact IDs.

From what’s already known, the correct match should be for:
  • ECU P/N: 37820-55A-Y73
  • ROM ID: G387-100883
  • Calibration: KEIHIN/CYG1-400000
  • File size: 512 KB
  • Stickers: YU / AYU

If you want me to check/verify what you have: upload your current 512KB .bin here, and also post a HEX header (first 256 bytes screenshot)</b] or a header screenshot so we can confirm it’s a proper full read (not partial/corrupted).

Also confirm: was this read done as a true full OBD read (512KB) using PCMFlash/Scanmatik, or was it partial?

I DONT HAVE FILE I NEED FILE

I DONT HAVE FILE I NEED FILE

You need a matching factory stock file, but if you don’t have your current 512KB full read, nobody can “send any bin” that will be correct unless it matches your exact ECU IDs.

Post (from your ECU sticker/labels) these exact items:
  • ECU P/N (example you mentioned: 37820-55A-Y73)
  • ROM ID (example you mentioned: G387-100883)
  • Calibration string (example you mentioned: KEIHIN/CYG1-400000)
  • Sticker codes (example you mentioned: YU / AYU)
  • Confirm: is this for Honda City 2014 GCC CVT (and engine code if you know it)

Also tell me what you need it for:
  • ECU is bricked/dead (no start / no communication), or
  • you just lost your original file

If you want an actual working file, the minimum is: 37820-55A-Y73 + G387-100883 + KEIHIN/CYG1-400000 + file size 512KB (YU/AYU).
