KTag Backup Manager — Split, Inspect and rера** ECU Dumps​#

v1.43. Unpack KTAG backups, separate micro flash EEPROM, safe rера** workflow

Overview
A lightweight utility designed for Alientech KTAG backup projects. It unpacks full ECU backups, separates Micro, Flash and EEPROM, shows basic ECU/File info and lets you rера** edited parts back into a single backup for bench or boot workflows.

Frequently Asked Questions​#

Which Windows version is recommended?
For maximum stability during ECU flashing and diagnostics, a clean installation of Windows 10 (64-bit) is recommended.
Is it compatible with J2534 PassThru?
Most modern software versions support standard J2534 interfaces like Scanmatik 2 Pro, OpenPort 2.0, and specific VCI adapters.

As mentioned in the post just above yours, you need to check your Private Messages (DM) or the Welcome Message you received upon registration. On this board, the password is often sent automatically to your inbox to prevent leeching.

If you still can't find it:

1. Make sure you have pressed the Thanks and Reputation buttons for the uploader (Bin).
2. Check your spam/junk folder if it was an email notification.
3. Send a polite PM to the author if the automated message didn't arrive.

Regarding the tool itself:
This utility is very useful for KTAG users working with Tricore or MPC5xx ECUs. It saves a lot of time manually hex-editing the single backup file when you just need to swap the EEPROM data into a donor ECU or extract the Micro for patching.

Just remember to always verify the checksums with your main tool (K-Suite, WinOLS, etc.) before writing the rерас*** file back to the unit, especially if you modified the maps in the Flash partition.

i want to notice that utility does not work correctly. 1) need ktag attached and with ktag clone give external exception EEFACE.Anyone can show that is really working in any way? thanks

That's a valid technical observation. Let me address both points:

1) KTAG Required / Clone Compatibility

The EEFACE exception is a classic dongle protection check. The utility is likely reading the KTAG's USB serial number or FTDI chip ID for license validation. Clones typically have generic or mismatched serial numbers, so the protection routine throws that external exception.

This means:

• The tool was designed to work only with original KTAG hardware connected as a dongle/license key.
• Clone KTAG units will fail the check — this is by design, not a bug.

2) Does it actually work?

Good question. If anyone has tested this with a genuine KTAG and can confirm it works properly (backup split, EEPROM extraction, rера**), it would be helpful to share a screenshot or brief confirmation here so others don't waste time.

Workaround suggestion:

If you just need to split/merge KTAG backup files (Flash + EEPROM), you can do it manually:

• Open the full backup in a hex editor (HxD, 010 Editor)
• Check the KTAG backup structure — typically the EEPROM block is appended at a known offset after the Flash section
• Split or replace the EEPROM portion and recalculate checksums if needed

If you share the ECU type (e.g., EDC17, MED17, SID208, etc.) and the file size of your backup, I can help you identify the exact Flash/EEPROM split offset.

KTag Backup Manager — Split, Inspect and rера** ECU Dumps 1.43 On Windows 11 x64 Pro it gives an error "External Exception EEFFACE" . To test the program, I used previously saved data from EDC16 by the Chinese KTAG

hi friends
your right also this soft give me the same error
i tried with windows 11 64bits also windows 7 32bits and give the are error

Hey, welcome in.

Your report lines up with what automf14 and Oleksandr already posted, so at this point it looks like a consistent behaviour of the tool rather than something on your machine:

What the evidence shows
In Oleksandr's screenshot the dialog fires while the status bar still reads Initializing ..., with no backup loaded and every field empty. That means the exception happens before any file parsing, so the OS and bitness are irrelevant — which matches you getting the same result on Win11 x64 and Win7 x86.

Inference (not confirmed by the author)
External exception EEFFACE in a Delphi-built app is typically a protection/wrapper layer aborting, and this utility is built around Alientech KTAG projects, so the most likely cause is a hardware/licence check against an original KTAG (USB serial / FTDI ID). Clone units and "no dongle attached" both fail that check the same way. Nobody in this thread has yet posted a working run with a genuine KTAG, so I can't state that as fact.

Practical workaround
KTAG full backups are just concatenated regions, so you can do the same job by hand:

• Open the backup in HxD or 010 Editor
• Identify the Micro / Flash / EEPROM boundaries from the total size and the known region sizes for your ECU family
• Cut or paste the region you need, then let K-Suite / WinOLS handle checksums before writing

For an EDC16 backup that is usually straightforward. Post the exact ECU type (e.g. EDC16C31, EDC16U34) and the exact file size in bytes of your saved backup and I'll give you the offsets to cut at. A screenshot of the file properties or the hex header is enough.
