S55 Tuning - For BMW F80 F82 M3 M4 F87 M2 COMPETITION.

Bootmod3 is the tuning solution for the BMW M3 F80, M4 F82/F83 and M2 Competition F87 with the S55 engine. You flash the original engine computer (DME) through the OBD port, using the app on your phone or laptop.

Nothing to remove and nothing to ship: you connect the adapter to the OBD port, pick your map in the bootmod3 app and within a few minutes the tune is installed. Switching between maps or going back to fully stock is always possible.

Who is bootmod3?

Bootmod3 is the platform of Pro Tuning Freaks from Canada, the pioneer of cloud-based flash tuning for BMW and the most widely used tuning platform for the F and G series worldwide. All maps and datalogs live in the cloud, the software receives continuous updates and there is a worldwide network of professional tuners behind it.

There are other flash platforms for BMW, such as MHD. We almost always recommend bootmod3: it leads the way in support for new models, CustomROM offers features you will not find elsewhere (map switching via the steering wheel, AntiLag, flexfuel) and the full Map Editor gives every tuner room to work. On top of that, we use it every day in our own workshop, so our support comes with it.

What you need

In addition to the license, you need a bootmod3 wifi adapter or ENET OBD cable for flashing, available separately in our shop.

If your S55 runs a software version from March 2019 or newer, the DME is locked and needs to be unlocked first. We do that at our workshop with the DME bench unlock.

Prefer to have it installed?

You don't have to flash it yourself. We can also install the license and the tune for you at our workshop in Elburg, the Netherlands. After your order we will contact you to schedule an appointment. Questions beforehand? Contact us, we are happy to advise.

System requirements

• iOS 13 or higher, Android 5.0 or higher
• Windows 10 or higher, macOS 10.15 (Catalina) or higher

Good to know

Tuning can affect your factory warranty and not every modification is allowed on public roads. Features such as AntiLag and modifying or removing emissions-related components are intended for track use only.

Eyeing a new car? Your bootmod3 license can be transferred once to another car with the same engine. First restore the original software and lock the DME, then transfer the license in the app to the new VIN. Separate OTS bundles and custom maps do not transfer.
