CustomROM V2: Enhanced Software Capabilities

Building upon the foundation of CustomROM V1, CustomROM V2 offers:

  • Sequential Port Fuel Injection (PI) Control: Enables precise fuel delivery strategies, including automated fuel mass-based splitting between direct and port injection systems.

  • Advanced Boost Control: Introduces support for a REV2-connected MAC solenoid, allowing for refined boost management, especially beneficial for aftermarket turbo setups.

  • DirectPWM Integration: Utilizes existing DME outputs to send PWM signals directly to the REV2 Controller, facilitating rapid and direct control of connected components like boost solenoids and fuel injectors.

  • Live Tuning: Allows real-time adjustments to tuning parameters without the need for reflashing, streamlining the tuning process.

  • Comprehensive Safety Protocols: Implements over 40 customizable safety strategies, including per-cylinder ignition and injector cutoffs, coolant over-pressure detection, and knock-based ignition timing corrections.

  • Custom Launch Control: Provides configurable launch settings, enabling optimized acceleration from a standstill.

  • Line Lock Functionality: Facilitates controlled burnouts by locking the front brakes independently, activated via steering wheel controls and brake pedal input.

  • Ethanol Content Display: Displays ethanol percentage directly on the vehicle's RPM gauge, offering real-time fuel composition insights.

REV2 Controller: Advanced Hardware Integration

The REV2 Controller complements CustomROM V2 by introducing hardware-level enhancements:

  • FlexRay Communication: Employs the high-speed, fault-tolerant FlexRay protocol for communication between the DME and REV2, ensuring reliable data transmission.

  • DirectPWM Outputs: Offers direct control over connected components without communication protocol overhead, enhancing response times for critical systems.

  • Sensor Inputs: Supports various sensors, including fuel pressure, coolant pressure, ethanol content, nitrous bottle pressure, exhaust gas temperatures, turbine speed, ride height, and methanol flow and level sensors.

  • Actuator Outputs: Controls up to eight high-impedance port fuel injectors, boost control solenoids, secondary fuel pumps, nitrous solenoids, methanol/water injection systems, and line lock solenoids.

  • Motorsport-Grade Construction: Features an IP66-rated enclosure and a Mil-Spec wiring harness, ensuring durability and reliability under demanding conditions.

Burble activation has been fixed for mild hybrid cars, due to newly introduced limiters and activation switches for the mild hybrid cars, this was not present in our old version of OTS maps.

Moreover, a boost pressure plausability code would show up on mild hybrid cars as well, this has now been addressed.

S58 CustomROM Release

S58 CustomROM support is Now Available !

















































Over the past year we've worked tirelessly to build significant automation that would allow us to port our CustomROM features across software updates as they get released for vehicles we support. We applied it to the S58 and managed to add support for all 8 S58 software versions including all G8x M3/M4 and G9x X3M/X4M.

















































FlexFuel, AntiLag, MapSwitching, LiveAdjust Tuning, In-Dash Ethanol Content Check, and close to 5000 tuning tables available in the bm3 Map Editor.

















































🔸Any new OTS Maps available?
























Two new MultiMap OTS maps, Stage 1 and a Stage 2. Each MultiMap contains 4 steering wheel switchable map slots. FlexFuel and Antilag are built into all of them and scale from 0 to 100% ethanol.

















































🔸Can I get this if my DME is currently LOCKED and requires a FEMTO Unlock?
























Yes. You need to purchase a BM3 license, activate your bootmod3 software license, and then send your DME to Femto. We provided Femto with means to load BM3 CustomROM software along with our Transmission Limiter Bypass. Once you get your DME back from Femto, it'll have the BM3 CustomROM on it with their unlock.

















































🔸Can I get this if my DME is Femto UNLOCKED?
























Unfortunately, due to specifics around the Femto unlock, you will need to have your DME resent to Femto for CustomROM software to be applied along side their unlock. Your DME would lose its Femto unlock if we allowed a full flash of the software to be done. If you were to flash the MultiMap without resending it to Femto, you will simply have MultiMap's map1 power available and no CustomROM features.

















































🔸Do I need to clone my DME for this?
























No.

















































🔸Can I get this if my DME is OBD or Bench unlocked (older X3M/X4M)?
























Yes, flash away.

















































🔸Is there an S58 Flex Fuel hardware kit?
























Our S58-specific Flex Fuel kit hardware is on the way so be on the lookout! Any other flex fuel kit based on the off the shelf Zeitronix ECA2 CANBUS controller can also be used. In the meantime, you can use the LiveAdjust screen in the app to scale your ethanol content on demand.
