OVERVIEW

bootmod3 (BM3) is a cloud-based flash tuning platform for the BMW F and G series. It is not a piggyback module — it writes a full calibration to the factory DME over the OBD port, and it has been developed and tested in-house since its November 2016 debut, with new features and updates added regularly.

Build the tune for your B58 powered BMW and move from stock to full race calibration, and everywhere in between, with a map switch in the app. Flashing takes a matter of minutes and can be done in your own driveway anywhere internet access is available, using a Windows or macOS browser or the bootmod3 apps for iOS and Android.

This listing is a software license for one vehicle. It is not a physical part. An activation link is emailed to you after payment.

TECH RESOURCES

Additional Parts Required

ECU Unlock Service for BMW B58 Engines — vehicles carrying the November 2019 or later software update require a DME unlock performed on the bench before OBD flashing is possible. Confirm your software level with Speed Logic before ordering.
bootmod3 OBD WiFi adapter, or a generic OBD2-to-Ethernet (ENET) cable — one or the other is required to connect the car to bootmod3. Speed Logic does not stock these as separate listings; the WiFi adapter can be added using the bundle option in the variant selector above.
A compatible device — an iOS or Android phone when using the WiFi adapter, or a Windows/macOS laptop (Google Chrome recommended) when using an ENET cable.
Ethernet-to-USB adapter — only if your laptop has no built-in Ethernet port.
Internet access at the vehicle — bootmod3 is a cloud platform and must reach the bootmod3 servers to download and flash a map.
Battery charger or tender, recommended to hold voltage steady for the duration of the flash. Bootmod3 does not publish a minimum voltage figure; this is standard practice for any DME flash.
