From unboxing to your first drive in just a few minutes.

  1. Download & install the software You're already here – download the free Windows software (link below in the Demo & Download section). Requirement: Windows 10 / 11 (64-bit).
  2. Plug in & ignition on Plug WiFENIX into the 12-pin diagnostic socket and switch on the ignition.
  3. Connect to Wi-Fi On your computer, connect to the Wi-Fi network FYP25-WiFi… and tick "Connect automatically".
  4. Open the software Start the WiFENIX software and select your vehicle.
  5. Connect to the dongle In the software, click the Wi-Fi icon – after a few seconds your dongle appears. Select it, click OK, done.
  6. Off you go! 🏁 Now you're reading live what your engine is doing.
Important on first launch: When Windows asks whether the software may access private and public networks, always click Allow / Yes. Only then will the software detect the dongle reliably.

Note: Without ignition, the control units send no data. After about 10 minutes WiFENIX switches to sleep mode – with the ignition on it wakes up again automatically.

🚗 Your model isn't listed?

No problem – just get in touch. In most cases we can add your vehicle: you record a few drives with your WiFENIX, we build your model from them – and everyone gets it as a free update. Not driving a Renault? The same control-unit families were used back then in other makes too – just ask, and we'll check your control unit.

📍 Where is the diagnostic socket?

WiFENIX plugs into the original 12-pin diagnostic socket. This is what it looks like:

Where exactly it sits depends on the model. Roughly:

  • In the interior / fuse box: e.g. Renault 19 and Clio.
  • In the engine bay: e.g. Renault 5, R21, R21 Turbo and R25.
  • In the rear: on the rear-engined Alpine models – the engine sits at the back, and so does the socket.

Tip: The socket sometimes hides behind a dust cap. An interactive socket finder per model will follow later.

🎬 Try the software & demo

Want to try WiFENIX before you set off – or even before you buy? Download the software and a real recorded drive and take a good look at everything.

1. Download the software (free) ⬇

Windows 10/11 (64-bit) · DE, EN, FR, ES, IT, PT, NL, PL, CZ, RU

2. Download the demo drive ⬇

Recorded drive of a Clio Williams (F7R) · approx. 1 MB

How to play the demo drive

  1. Install the softwareIf you haven't already – see the button above.
  2. Download the demo fileSave the file above (e.g. in your "Downloads" folder).
  3. Start the software & pick the modelOpen the WiFENIX software and select Clio Williams 2.0 (F7R) as the vehicle and confirm – then all values match the recording.
  4. Open the file & exploreUse the folder icon to open the file you downloaded earlier. The simulation starts automatically – now you can explore everything in the Sensors, Graphs, Live values and Dashboard tabs.

Tip: alternatively, a double-click on the downloaded file opens the software directly with the recording loaded – provided your system recognises the file type. You then select the vehicle as described above.

No device needed: for the demo you only need the software. To read your own car live, you need the WiFENIX dongle.

⚙️ More features

Good to know: WiFENIX is a read-only device. It reads values and the fault memory, but cannot write, program or change anything in the control unit. Your car stays 100 % original.

The Expert Mode

In everyday use the software stays deliberately clean – even beginners find their way around instantly. If you want to go deeper, unlock Expert Mode with a single click:

  • Raw data capture directly from the control unit
  • Pulse-generator signal source – for standalone bench operation of a control unit
  • Live connection statistics: sampling rate, frame errors, checksums
  • Advanced views and settings
  • Histograms across all sessions – show you where your engine really runs: RPM, injection, knock

❓ Frequently asked questions

Compatibility

Will WiFENIX fit my car?
If your vehicle has the 12-pin diagnostic socket and a SIEMENS, FENIX or RENIX control unit (1/3/3B), the chances are good. The quickest way to check is the vehicle list above.
My model isn't in the list – what now?
Just get in touch. In most cases we can add your vehicle: you record a few drives with your WiFENIX, we build your model from them – and everyone gets it as a free update.
Does it also work with makes other than Renault?
Possibly – the same control-unit families were used back then in other makes too (e.g. the Skoda Favorit). Just ask and we'll check your control unit.
Can I use one WiFENIX for several cars?
Yes. You can use your WiFENIX for all supported vehicles – there's no limit. In the software you simply select the matching model.

Software & devices

Do I need a Windows laptop?
Yes. The software runs on Windows 10 / 11 (64-bit). An app for iOS and Android is in development.
Is the software available for Mac?
Not at the moment. macOS support may follow later – depending on demand.
What does the software cost? Is there a subscription?
The software is free, and so are updates – no subscription, no ongoing costs. The dongle is all you need.
Do I need internet?
Not for reading and recording – that runs completely offline via the dongle's Wi-Fi. New vehicles and updates, however, are fetched by the software from an online database. If you want to stay up to date, connect the laptop to the internet from time to time. It's not required for operation.
Which languages is the software available in?
German, English, French, Spanish, Italian, Portuguese, Dutch, Polish, Czech and Russian.
Do I have to activate the software or enter a key?
No. WiFENIX ships fully activated – no key, no activation step, no account. Install the software, connect, and get going.

Connection & operation

How do I connect to the device?
As soon as WiFENIX gets power, it opens its own Wi-Fi network called FYP25-WiFi… (with the device's serial number). Connect your computer to it just like to a router and tick "Connect automatically". Then open the software, click the Wi-Fi icon – after a few seconds your dongle appears. Select it, click OK, done. If it doesn't show up right away, a message with a manual connection option appears after about 10 seconds.
Windows asks for network access – what do I click?
Always Allow / Yes, and for both private and public networks. Only then will the software detect the dongle reliably.
What's the Wi-Fi range?
Up to 10 m. So the laptop on the passenger seat or next to the car is no problem.
Can I leave WiFENIX permanently in the car?
Yes, that's what it's made for. With the ignition off it goes into sleep mode and wakes up by itself the next time you start. It records every drive – up to 60 hours, after which the oldest recordings are overwritten.
Will it drain my battery?
Power consumption is very low – uncritical even after weeks. For longer periods of standstill you should unplug the dongle; and the battery of classic vehicles should be charged regularly during long layups anyway.

Safety & originality

Can WiFENIX damage my car?
No. WiFENIX is a read-only device – it only reads, it doesn't write or change anything in the control unit. Your car stays 100 % original. Just observe the safety notes on mounting.

Purchase & delivery

What's included?
The WiFENIX diagnostic device, a quickstart guide and the Windows software as a free download.

⚠️ Safety notes

Mounting in the engine bay: WiFENIX sits firmly in the socket – to be completely safe, additionally secure it against falling out, e.g. with a cable tie or wire. On some models (e.g. R21 Turbo) the diagnostic socket sits close to the exhaust system. A device that falls out could land on hot parts there – fire hazard.
  • Connect only to the 12 V on-board electrical system via the designated diagnostic socket.
  • Do not operate the software as the driver while driving.
  • Do not open the device.
