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:
Exciting news from the bm3 electronics team! With the Rev1 version of our CANBus sensor hub board completed, and now focusing on an enclosure design, we have finalized our Rev2 design as well. As mentioned in our previous post, Rev2 board builds further on the Rev1 design by expanding its input sensing abilities and adds 6 outputs.
The smaller Rev1 board features configurable CANBus conversion for 2 frequency inputs (e.g. flex sensor input), and 3 analog 0-5v inputs and will be a lower cost option for those looking to simply hook up a flex fuel sensor and possibly monitor any other sensors needed (e.g. low pressure side fuel pressure sensor on N55/B58) and be able to get Flex Fuel running using BM3 custom software enhancements right inside the DME. For flex fuel sensor integration, Zeitronix ECA2 and any other similar boards are also supported.
The Rev2 board keeps the 2 frequency inputs like the Rev1, adds 2 EGT sensor inputs, expands from 3 to 8 analog 0-5v analog inputs and adds 6 outputs. All i/o is canbus integrated for sensing and control of canbus connected systems, primarily the DME. Both boards have integrated WiFi/BLE and all configuration is done over WiFi and integrated with the bm3 app/editor for ease of use by end users and tuners. Stay tuned for the release of many of the other new features we’ve been working on over the past year and more to follow on this board as firmware development is completed.
In the previous two videos we demonstrated bootmod3's new custom code features integrated into the factory DME (ECU), namely on-the-fly map switching and rolling antilag, both of which are using steering wheel controls for triggers 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 and to spool the turbo without using brake boosting and slightshot your way forward when racing :)
In this video we're demonstrating another new tuning feature that is in the works by the bootmod3 dev team called FLEX FUEL. bootmod3 Flex Fuel integration is a set of custom tables predefined to tune your vehicle for dynamic aggression/power in the tune based on input from a Flex Fuel sensor. In this case we're using a Continental flex fuel sensor with a Zeitronix ECA2 kit which sends Flex Sensor's data over the CANBus which the DME handles in real-time to make the tune more or less aggressive based on ethanol % in the fuel. We previously made map switching on-demand work using the steering wheel controls. Now, there's a new option to also enable Flex Fuel in the tune and define separate tables for tuning for ignition, fuel, load/torque, various safeties, and many others. Tuning details behind getting a flex fuel tune working are also very straightforward and very powerful. A tuner defines your base map or maps (1 through 4) which you can select through the steering wheel (example: Map1: Stage 1 93 map, Map 2: Stage 2 93 octane, Map3: Stage 2+ 98 octane, Map 4: Stage 2+ race gas) . Any or all of the 4 switchable maps can now be configured as ENABLED for Flex Tuning. When enabled, data from the Flex Fuel Sensor is used to scale between say a pump gas E0 (no ethanol tune, or E10) to a full E85 or E100 (100% ethanol) tune. If sensor detects no ethanol then the scaling leaves the base maps alone without scaling them upwards in aggression. If the sensor detects and sends say 50% ethanol to the DME then the DME can be set to change ignition, fuel, load/torque and many other tables to increase power levels due to ethanol's much higher octane over petrol/gasoline.
In this demo, we're demonstrating on a 2015 BMW F80 M3 which starts out with a 20% ethanol blend in the tank. Those that enjoy the details can see the blend factors are set for 0.50 for this ethanol level just as an example. Currently there are 3 main blend factor tables, ignition, fuel and torque, and they can be individually used to scale among many tables required for tuning Flex Fuel, from cold starting the car with full ethanol in the tank to full on power. In the end of the video we add some more alcohol and you can see in the bootmod3 dashboard how the Flex % goes upwards from 20% to 27% as the fuel system catches up and the fuel in the tank gets a chance to blend as it isn't instant.
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!
Over the past few months we've worked tirelessly on enhancing the user experience for mobile app users. We did a complete rewrite of our OBD Agent software and integrated it right inside the mobile apps for iOS and Android!
This has allowed us to provide 2 new convenience connectivity options for mobile:
1) Direct ENET Cable connection to an iOS or Android device without having to use the BM3 WiFi Adapter
2) For WiFi connectivity, remove the requirement to use the hotspot between the BM3 WiFi Adapter and your iOS / Android device. Instead, the mobile devices now connect to BM3_NET WiFi network running on the BM3 WiFi Adapter. Same hardware as before and all it requires is an SD card firmware update.
In addition to removing the hotspot, since BM3 OBD Agent software no longer runs on the BM3 WiFi Adapter, the SD card of the device will require no future updates as OBD Agent software is changed. In the past when OBD Agent software changed, there were times on occasion where SD card required to be removed and updated. Now that the OBD Agent is embedded inside the mobile apps this SD card updating is no longer necessary across OBD Agent/App releases which means less to manage for end users on an ongoing basis.
0.20.020 OBD Agent has also been updated for macOS and Windows operating systems running on laptops/desktops vastly improving its startup time, stability and performance.
Along with this update, a number of various bug fixes and updates in the UI have been released both for the Web and Mobile as well as various Map Configuration screen additions such as upgraded HPFP pump solutions from Dorch Engineering and Spool Performance.
Incredible results from this F90 M5 from Steve, customer from Quebec, Canada! Only hardware modifications on his F90 M5 are downpipes and a lower temp (90C) thermostat used on a 550i to keep the oil temps cooler and a quick flash to bootmod3 OTS (Off The Shelf) Stage 2 E30 octane map.
