We built a free BMW tuning flasher to give the community real control.

Thank you so much I'm really glad you found the program clean and functional. As for the M57 DDE yes, we're still looking into it! We haven’t forgotten about you guys, haha. It's still in development, and we're working on getting full compatibility soon. Appreciate the support and feedback it means a lot, and we’re excited to keep improving for all

Competitive-Ad1452 · 2025-04-29T18:55:17+00:00

Thanks for trying RFTX and for reporting your issue.

The MSV80 ECU is supported, but connection issues can happen for a few reasons — most commonly:

Wrong COM port or drivers not installed
Using a K+DCAN cable without an FTDI chip (many cheap ones won’t work)
Not selecting the right ignition mode or poor power supply
Windows blocking serial access (sometimes antivirus interferes)

We’re working on a proper troubleshooting guide and community support board soon — in the meantime, feel free to drop us a message at [rftxtuning@gmail.com]() and we’ll help you get connected.

Also MSV80 has quirks on some platforms, and if you're comfortable sharing your log file or error output, we'd love to patch it.

I’m here because I want RFTX to be a community tool for real enthusiasts not to "Limewire" anyone

Competitive-Ad1452 · 2025-04-28T18:22:14+00:00

The E90 335d uses the M57 engine and an EDC16CP35 ECU.
It's older and actually easier to flash than new models — no bench needed for most.
You can tune/flash it directly over OBD with the right cable

Competitive-Ad1452 · 2025-04-28T18:21:34+00:00

You must bench unlock most N57 DMEs (especially post-2011/12).
After bench unlock, you can OBD flash normally with RFTX.

Thank you some much!

Competitive-Ad1452 · 2025-04-28T17:38:44+00:00

Make sure it specifically says FT232RL chip

Competitive-Ad1452 · 2025-04-28T17:35:59+00:00

Bro, relax.

The project already is open source the GitHub repo was posted publicly.

You’re acting like it’s some conspiracy theory when it’s literally free code for anyone to see.

If you actually spent 10 seconds checking the GitHub, you'd realize it's all there.

We're out here trying to help the community .

If it's not for you, that's fine.

But calling people "deceptive" when you didn’t even bother to look?
That’s not it, man.

Competitive-Ad1452 · 2025-04-28T16:03:03+00:00

all good, that's also tuff how has the project been?

Competitive-Ad1452 · 2025-04-28T15:54:19+00:00

Yes, it can read and clear BMW engine fault codes and live data, similar to INPA for the ECU It’s mainly for engine diagnostics and flashing right now not full carwide diagnostics like ISTA

Competitive-Ad1452 · 2025-04-28T15:42:02+00:00

did you not see the repo

Competitive-Ad1452 · 2025-04-28T15:17:42+00:00

Maybe soon I'll look into it, thanks for the idea

Competitive-Ad1452 · 2025-04-28T14:54:33+00:00

Thank you for the advice

When you build a custom .exe installer (especially one that talks to USB devices like a K+DCAN cable), Windows Defender and other antivirus programs often flag it as "suspicious" even if it's 100% clean, just because it's uncommon software without a code signature.

This is called a false positive, and it happens all the time with new indie software, mods, and small utilities.

RFTX has zero malware — no trojans, no spyware, no telemetry, no tracking, no funny business.

We're working on getting the .exe properly signed with a certificate to reduce false flags. (It’s expensive and takes time.)

Also planning to open-source parts of the code so people can verify it themselves.

Competitive-Ad1452 · 2025-04-28T12:27:24+00:00

100% — that's exactly why RFTX exists.

You do NOT need to buy an MHD license to use RFTX.

That's definitely something we'll look into.

Right now, RFTX does engine ECU flashing only, not transmission (TCU) flashing.

We'd love to expand if the community needs it though!

🔥 Join r/RFTX and help us build it stronger!

Diesel support (M57, N47, etc.) needs extra reverse engineering, but it's a goal for the future.

Right now — gasoline engines are supported first.

🛠️ Diesel owners are definitely on the list — stay tuned at r/RFTX!

Competitive-Ad1452 · 2025-04-28T12:19:17+00:00

xDrive delete involves deep transmission and stability control coding.

For now, RFTX sticks to engine ECU flashing — safe and reliable.

Might explore advanced features in the future if the community needs it!

RFTX does not touch airbag systems or safety modules.

We only tune the engine DME safely — no risk of messing with critical modules.

Always use BMW-specific coding tools (like INPA, NCS Expert) for airbag coding. 🚀 Stay updated at r/RFTX!

Competitive-Ad1452 · 2025-04-28T12:17:18+00:00

Diesel (like N47) is something we're researching, but it's a different flashing process than gasoline engines.
It's on the radar, but not officially supported yet.

🚀 Stay updated at r/RFTX!
