How to flash your BMW F series with bootmod3

No need for special cables or proprietary devices - users only need OBD2 ENET CABLE - available on Amazon for $20

We decided to remove our official guide and include one of our customer's forum reviews here instead as it was really great!

Hi, BM3 OBD Unlock and Flash for the BMW F series is officially out, I just flashed bootmod3 (BM3) using proTUNING Freaks' (PTF) new OBD Unlock feature! It was a quick and flawless process! Here are the quick and easy steps to get your BMW tuned within minutes without removing the DME 

If you haven't already purchased BM3, go here: https://www.protuningfreaks.com/coll.../bootmod3-menu  
After purchasing, PTF will email you an Activation Key which will be used for activating your BM3 account.

0 - Ensure any firewall and network protection is turned off as it will interfere with flashing. This includes:

  • Windows and macOS firewall and Windows Defender
  • Any Norton or McAfee or 3rd party anti-virus or network protection software you might have. Disable it fully.
  • If you skip this step and leave them running you'll have connection issues and it may not connect and might fail at 1%
  • If you're using an adapter for the BMW ENET cable to connect to your laptop the generic ones will NOT work on macOS in most cases. You need an Apple adapter which is sold at the Apple store.

1 - Create an account at http://www.bootmod3.net

  • Install it once downloaded, and proceed to Step 3


2 - Connect your computer to your car using an ENET cable (OBD to Ethernet), similar to the one found here: https://www.amazon.com/Interface-Cab...70_&dpSrc=srch
- Press the start button so the dash cluster turns on, but do NOT start the engine. You'll see the gas tank level gauge move and show level of fuel in the tank.
- Start the bootmod3 OBD Agent and leave it running

4 - On the bootmod3.net page, log in and click Activate Vehicle.

5 - Copy and paste the Activation Key that was emailed to you and then click Activate Vehicle to register your vehicle to your account!
NOTE: The activation screen will show a Vehicle Software Details below the VIN and activation key. If you're not seeing them showing remove the battery ground cable (brown wire) from the battery for 3 minutes to reset all ECUs and try again.

*At this step, a stock map will be automatically created for your vehicle/software version which you will see under "My Maps". This is how you go back to full stock! Awesome right?


***A battery charger is HIGHLY recommended before proceeding to the following steps!!*** In case you're wondering, I took the risk and did not use a battery charger. If your car was sitting in the garage for some time (mine sat for a week), I suggest you go for a drive if you absolutely cannot get a battery charger, but be warned you are taking a risk! I'm not not responsible for your errors or decisions.

6 - Once activated, you may select an off the shelf (OTS) map for your octane and modifications under OTS Maps, Stage 1, 2, E85, whatever your heart desires.


7 - Go to My Maps where you will find your new tune, ready for flashing! Click the map you want, click Flash, and then click PRESS HERE TO FLASH NOW. Make sure your headlights are turned off, doors are closed, and your seatbelt is on to prevent ECUs from going to sleep. It'll take just a few minutes to unlock your DME and flash the new tune onto your car!


8 - Once flashing is complete, it'll ask you to turn off the car for 20 seconds and then you can start the engine! CAR IS UNLOCKED, FLASHED, AND READY TO GO FOR A DRIVE! 

As simple as FLASH AND GO! Awesome! 
I hope this helps and that you enjoy your newly tuned BMW with the greatest tuning platform available! You have the option to get new OTS maps for different fuels and modifications! And if you want to take it a step further, you can get a custom tune! PTF updates the OTS maps periodically for new features and performance enhancements.
