Frequently Asked Questions

What is bootmod3?
bootmod3 is the first custom tuning platform for the BMW F series vehicles.

What do I need from you to get this going?

2) bootmod3 mobile app - currently available for Android in the Google Play store, click here. iOS app is just around the corner along with a Web-only version.

3) BMW ENET (OBD) cable - available on Amazon, one of them available here:

4) bootmod3 OBD Agent software - free download from dropbox to run on your laptop. Setup instructions provided, click here. Agent software connects your vehicle's OBD port to bootmod3 servers and the device is not VIN locked.

Optional: OBD Agent hardware device - Convenience always-on option, alternative to #4 above. Why? Removes the need to use a laptop in the car and comes preconfigured with the agent software for connectivity to bootmod3 servers and connects to your phone over WIFI.

How does bootmod3 flash the car. Does it need internet?
bootmod3 is the first cloud based tuning platform. What this means is that we provide all the tools necessary to securely and most efficiently tune the car, through the Web, much like how you have your email with Google (Gmail) instead of hosting your own mail server. Data lives on our servers and the system provides enhanced features such as map editing and configuration, built-in custom tuning with tuners in our Tuner Directory without depending on emailing csv files and map files back and forth. Tuners and end users can enjoy a high level of efficiency when custom tuning either on a local dyno or working with each other remotely.

Can I use bootmod3 with more than one car?
bootmod3 license applies to 1 VIN. OBD Agent hardware device however can be used on multiple cars.

Can I just buy the flasher or just the logger as I don't care for other features?
We strongly believe a tuning platform should have all of the features provided and we are adding more all the time without additional licensing fees. In case of higher demand for portions of bootmod3 features such as offering flash-only or logging-only licenses, we do have the means to separate them out. Please inquire separately at this time.

Do I need to remove my DME and send it out for unlock?
Port flashing without DME removal is now available for the S55 with other engine support (N55/N20/N26/S63TU/N63TU) coming in the next week or two. 

Do you have any authorized dealer shops who can install this for me?
Absolutely. You can get in touch with any of our authorized dealers listed on our website and get bootmod3 installed. NOTE: Prior appointment scheduling is required. Labour cost install is to be inquired with the shop you're looking to work with.

How do I reach you if I have an issue or need help?
Open a tech support ticket with us on our support website and one of our staff will reach out to you:


I see the Stock Tune under My Maps. How do I get a tune (OTS map) to flash on my car?
Go to the OTS Maps screen and click on the OTS Map you'd like to flash on your car and proceed with flashing. You can choose any of the OTS Maps available.

Can I run E85 or meth and do you have OTS maps for these?
Yes. We have E30 (30% ethanol) blend OTS maps available. Full E85 maps are custom and can be done with any of the tuners listed in our tuner directory.

Do you offer backend flashes to run with a JB4 if I use it for methanol injection or secondary port injection?
Our OTS Stage 1 and Stage 2 maps are great backend flashes as they raise load and torque targets far higher than stock allowing the DME and TCU to run as close to actual values as possible. 1 map is included with your license purchase, and you can use it as your BEF.

How do I datalog?
Using the bootmod3 mobile app and agent running in the car while connected to the bootmod3 servers (cloud).

Do I need to always have a laptop with me in the car to run the agent? Do I need the device always plugged in?
No. Agent that runs on a laptop or hardware WIFI device is only required to be used if using the bootmod3 app features. Otherwise, no need for anything to be plugged into the OBDII port.

What's the difference between bootmod3 and JB4?
bootmod3 reprograms the vehicle's factory engine control unit (DME) and in some cases other ECUs such as the transmission control unit (EGS/TCU). JB4 is a boost controller with ability to run a methanol pump or secondary fuel injectors, features not available to the DME at this time. TorqByte is another alternative as a meth controller, much more advanced and with finer control from the tuning point of view.

Can I tune my own car with bootmod3?
Yes! You can go into the Stock Tune and do 'Save As' another map so your stock tune stays in tact and you can start tuning it yourself or with your preferred tuner/shop.

Here are some videos created by Cary Jordan (CaryTheLabelGuy), one of the tuners using bootmod3's custom tuning features:

Will this void my warranty?

As with any aftermarket hardware modification on the car or any tuning, there is a chance the dealer may refuse or void the drivetrain portion of your warranty. Many dealers are highly tolerant towards modifications and if you don't have one, find yourself a friendly Service Advisor ;)

I'm moving on to a different car. Can I re-sell my license?
Yes. Bootmod3 is the only BMW F series flash solution where the license can be resold and/or transferred to a new VIN when/if you decide to move on for any reason. Having re-sale value is a great advantage to choosing bootmod3 for your tuning which is NOT available with any other flash tune.
- License transfer is restricted to the original order purchase and buyer. Transferred licenses cannot be transferred more than once.
- Any previously purchased OTS maps and custom tunes by the original buyer are not transferrable due to map data incompatibilities between cars.
- To transfer a license you need to get in touch with support@protuningfreaks.com with your original order number, existing VIN and the new VIN to verify car being flashed back to the stock map.
