The most comprehensive bootmod3 software update is finally here and we are delighted to share it with everyone. Multiple features have been in development since mid 2020, many of which have been demo-ed to public throughout the time we were developing them. In December 2020 we completed development on the pre 2019 software S55s. We decided to finish 2019+ support as well and release it all together. It has endured a considerable delay from the initially planned release but we’ve managed to cover everything and in the process add even more functionality to the Map Editor and cover testing more extensively.
Our first release of the bootmod3 CustomROM is now ready for the S55 engine vehicles while we continue to work on adding these features to other vehicles in the bootmod3 lineup. Changes done for the S55 are being ported to the N55 vehicles followed by the B58.
To read about the bootmod3 CustomROM features available on the S55 engine refer to document below:
Really excited to show a render of the bootmod3 board undergoing firmware development. This board measures just 80mm by 50mm and already packs a heavy punch!
Board currently has multiple inputs (frequency and analog) and features CANBus integration and WiFi/BT for configurability. Rev2 of the board will also feature various outputs for activating/deactivating external aux systems (e.g. port injection, nitrous, etc), tuning it via tables integrated in the new bootmod3 editor.
Purpose of this board is to expand I/O capabilities of the factory engine computer (DME) and allow it to integrate with external sensors not already available on these cars (e.g. flex fuel sensor, meth flow/level sensor, port injection fuel injector duty, etc) and provide that data over CANBus to the DME for various tuning strategies. Any 3rd party products that support similar CANBus integration are also supported by bootmod3 (e.g. Zeitronix CANBus ECA2 flex sensor kit, etc). Integrating meth flow/tank level sensor data is a nice one and will allow for similar tuning strategies and failsafes as with flex fuel.
For this new demo we've managed to move controls for map switching to the steering wheel cruise buttons. You activate it by pressing the Resume button, and switching among 4 map slots (expandable if needed at a future date) by using the up/down button that are typically used to increase/decrease speed when cruise control is active. OEM cruise control functionality remains in tact and map switching can be done with the engine off, on and while driving.
This video was done on our 2015 F80 M3 with the MEVD17.2.G DME and applies to all S55 engine vehicles. Support for these features is in progress for all other vehicle models bootmod3 supports today.
Enjoy the vid while we continue making progress with many other advanced tuning features such as BM3 FlexFuel, Antilag and many others. Cheers!
