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.
In the previous video we demonstrated bootmod3's on-the-fly map switching using steering wheel controls allowing users to flash the car once and then select between any 4 maps that can be custom tuned to suit your modifications, octane and racing needs.
In this video we're demonstrating another new tuning feature that is in the works by the bootmod3 dev team called ANTILAG. To trigger it you simple press UP and hold on the cruise button on the left side of the steering wheel. While holding it, the DME switches to an internal antilag tuning strategy and tables where antilag RPM, ignition timing, accelerator pedal threshold, target load/boost and other values can be configured to dial it in as needed.
In this demo, vehicle is a 2015 BMW F80 M3, RPM is set to around 4k rpm, with accel pedal threshold at 100% (driver needs to go WOT to trigger it). In 1-2 seconds after triggering it, this car running ASR Kratos turbos, is able to hit 30psi! Lag goodbye! :)
We've added logic to ensure pressing the button UP on its own does not trigger ANTILAG mode until pedal and RPM thresholds are reached (both of which are tunable in the map). In addition, any of the 4 on-the-fly switchable maps can be set to have antilag enabled or disabled so the user can configure it to their needs (e.g. map1 no antilag, but map4 all the antilag/boost :)
bootmod3's rolling antilag feature is end user configurable from the app on-demand so any of its parameters can be altered on-demand while driving without turning the engine off and reflashing.
All the advanced tuning features such as map switching, antilag, flex fuel, are in progress of being ported as many if not all vehicles currently supported by bootmod3.
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!
