bootmod3 Engineering Update: Flex Fuel Tuning - CANBus Integration

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.

Hope you enjoy this video!

Rolling ANTILAG - Steering wheel controls - New Feature Demo - bootmod3

Rolling ANTILAG - Steering wheel controls - New Feature Demo - bootmod3

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. 

Hope you enjoy this video!

bootmod3: Selective Code Removal through Map Config - New Feature!

By Bertan Kazazic

bootmod3: Selective Code Removal through Map Config - New Feature!

We've added a new feature to enable users to selectively remove DTCs (Diagnostic Trouble Codes) on maps. In the cases of extensive hardware mods relating to the engine or its accessories there are times when its nice to turn off certain codes from coming up.

This DOES NOT in any way help resolve any mechanical issues one may be having. In some other cases, turning off a code will also not resolve an issue where additional custom tuning is necessary to fully address the problem.

However, in situations where the source/cause of a given code are well understood and users are comfortable turning it off to 'clean things up' this is a really neat feature to get that done.

bootmod3: Update for Map Configuration Screen

By Bertan Kazazic

bootmod3: Update for Map Configuration Screen

Map configuration screen descriptions for all settings and values available.

This should help those using the screen for the first time get a sense of what the values are if or when they may not be clear. I realize some of you will enjoy these being added right in the screen even though all of them are documented in the actively maintained bootmod3 User Manual.
