PTF Race Intercooler and Charge Pipe Kit - NOW IN STOCK!

By Bertan Kazazic

PTF Race Intercooler and Charge Pipe Kit - NOW IN STOCK!

We're really excited to finally be able to offer our PTF Race Intercooler and Charge Pipe Kit to our BMW F-series customers along with FREE shipping in the USA and Canada.

PTF Race Intercooler

The first and key hardware upgrade for all tuned BMW F series vehicles with N13, N20/N26 and N55 engines is the front mounted air to air intercooler.

Raising boost past stock on the OEM intercooler results in the DME (engine computer) to reduce power by reducing ignition timing due to increases in IAT (intake air temperature) and associated knock levels.

This PTF Race Intercooler features over twice the internal volume compared to the stock intercooler while also outflowing the stock unit by almost 20%. Intercooler features 9 charge rows in the lower section and 6 in the top stepped portion along with end tanks that have been CFD flow analyzed and made to include a vane to efficiently direct airflow into its high quality core.

PTF Race Intercooler fitment is confirmed on the following BMW F-series vehicles:

BMW 1-Series F20 F21
Model years: 2010-2018
Model: 114i, 116i, 118i, 125i, M135i (including x-drive models)

    bootmod3: 0.30.00 Release - CustomROM Features + New Map Editor + UI Enhancements

    By Dzenan Becic

    bootmod3: 0.30.00 Release - CustomROM Features + New Map Editor + UI Enhancements
    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:

    bootmod3 electronics: Rev2 CANBus Integration Board

    By Bertan Kazazic

    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.

    bootmod3 Engineering Update: Flex Fuel Tuning - CANBus Integration

    By Srdjan Bajat

    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!

    bootmod3 Engineering Update: CANBus Expansion Board Rev 1 - Render

    By Srdjan Bajat

    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.
