bootmod3 electronics: Rev2 CANBus Integration Board

bootmod3 electronics: Rev2 CANBus Integration Board
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.

1150whp 985wtq - S55 World Record - custom tuned with bootmod3!

It is our pleasure to have been part of this World Record setting project for the F8x M3 / M4 S55 engine platform. Factory ECU tuned using bootmod3 by Halim@HCPerformance. Impressive numbers and certainly leaves us wondering what is next for the S55 engine platform and to see this setup take on the 1/4 and 1/2 mile!

KRAS55Bi Turbos Surpass 1150WHP

It's with great pleasure that we at Global Motoring Group share the latest results of our KRATOS KRAS55Bi Turbo System.

As many of you may know, within a week of completing an engine build on one of our developmental S55's we were able to put down preliminary dyno results of 975whp and 752wtq @ 35psi on pump E85. As the turbos clearly had much more left in them combined with the fact that the 35psi run is very close to the limit of the factory map sensor, we decided to move forward with installing a 4 bar map sensor that would enable us to dial in additional boost. Moreover, being that the KRAS55 line of turbo systems will begin their public release this month, we wanted to update those who have been following our recent developments.

We reached out to Burger Motorsports as they had a Bosch 4 bar sensor upgrade kit that would work for the application. Unfortunately, their kit was not made for S55's, but with the help of Terry & Payam they were able to put a custom PnP harness together for us in only one day and promptly shipped it to us. Once installed, Halim@HCP rescaled the map sensor to prepare the car for further testing of the KRAS55Bi turbos. With the car dialed in on a HCP custom tune @ 41psi and Ignite E85 fuel (E83 Via Fuel-It Sensor) with an ambient temperature of 77°F our KRAS55Bi's produced the following results listed below.
