Hi! I downloaded the resetter tool, but the problem is, it does not detect e sys even though i have it on pc(successfully connected to car with it)

I tried putting e sys folder everywhere, with resetter tool in it, on desktop etc, but does not find it

That's a common issue. The EGS Resetter looks for E-Sys in a specific location — it checks for the default installation path and/or the PSdZData folder structure in a particular directory.

Here are a few things to check:

• Default installation path: Make sure your E-Sys is installed in the standard directory, typically
  Code:

  C:\EC-Apps\ESG\E-Sys

  or similar. The tool most likely scans for this exact path rather than searching your whole system.
• PSdZData folder: The tool specifically verifies you have a valid PSdZData folder. Make sure your PSdZData is located inside (or properly linked to) your E-Sys installation directory — not stored separately somewhere else.
• Don't move the tool around: Placing the resetter inside the E-Sys folder or on the desktop won't help — the tool searches for E-Sys by its expected install path, not relative to where the .exe sits.
• Run as Administrator: Right-click the resetter and select Run as administrator. Without elevated privileges it may fail to read certain registry keys or protected directories that point to the E-Sys installation.
• Check your E-Sys version: Which version of E-Sys are you running, and where exactly is it installed? Post the full path (e.g.
  Code:

  C:\EC-Apps\...

  or
  Code:

  D:\BMW\E-Sys\...

  ) so we can narrow it down.

If none of the above works, share a screenshot of your E-Sys installation folder structure and the error/message the resetter gives you — that will make it much easier to pinpoint the issue.

I am in the process of swapping the 8hp into a E46 and got the 8hp gearbox from f30 separately, i was quite excited at first until I realized that E-sys needs the ZGW module that's in the f-series cars. Without that, it seems I will have to look for alternative options. Nevertheless, I can’t really complain. Huge props for putting this together and sharing it.

Hello,
First of all, thank you for releasing this free tool. It is a very interesting project.
I have one technical question about the flashing procedure.
I understand the process:

1. Patch E-Sys folder.
2. Flash patched SWFL.
3. Reset ZGW / CAS(FEM) / EGS.
4. Restore original files.
5. Flash original SWFL.
6. Code EGS.

My question is about step 2, step 3 and step 5.
Let's say I have an F-series vehicle with an 8HP70 EGS and the supported SWFL 00000A81.

My current SVT contains:
BTLD 00000C7C 012.058.000
SWFL 00000A81 000.058.000
SWFL 00000CE3 058.004.001
CAFD 0000023F 016.016.035

Since the patched SWFL has exactly the same SWFL ID (00000A81) as the original, E-Sys normally does not offer a reprogram because the software version is already installed.

How do you force E-Sys to flash the patched SWFL?

• Do you edit the saved SVT_IST.xml (for example changing MainVersion to 000)?
• Do you modify BTLD, SWFL or CAFD?
• Or do you use a custom TAL that forces swDeploy regardless of the current version?

After restoring the original SWFL files, how do you force the second flash back to the original software?
I would really appreciate if someone could explain the recommended E-Sys procedure for the A81 / 8HP70 EGS.

Also, what exactly is meant by "Reset ZGW / CAS-FEM / EGS" after flashing the patched SWFL? Is this a Tool32 job, an ISTA service function, or simply a power cycle of these control units?

Thanks!
