AE&D Software
A professional Toyota/Lexus BEAN MPX laboratory for capturing, decoding, visualizing, logging, replaying and transmitting multiplex traffic from the golden era of Toyota electronics.
Toyota / Lexus BEAN MPX Laboratory
Built for reverse engineering, restoration, retrofit development, dashboard research, embedded gateway projects and serious Toyota/Lexus electronics work.
Product overview
BEANalyzer UltraPro connects to an external BEAN MPX interface, typically an Arduino-based adapter, through USB Serial. From there, it transforms raw Toyota/Lexus multiplex traffic into a structured workspace where messages can be searched, decoded, compared, graphed, recorded, replayed and used for gateway development.
Purpose-built for builders who modify, retrofit and push classic Toyota/Lexus electronics further.
BEANalyzer UltraPro was created for the people building real projects around classic Toyota and Lexus platforms: ECU tuners, swap builders, retrofit developers, dashboard hackers, restoration nerds and automotive electronics enthusiasts who want the car to evolve without losing its original soul.
When an aftermarket ECU, standalone controller or engine swap changes the original electronic ecosystem, BEANalyzer UltraPro helps you study the factory BEAN MPX traffic so you can understand which OEM messages keep the dashboard, body electronics, climate panel and warning logic alive.
Use captured and decoded messages to design hardware and software that preserves factory behavior, restores missing signals, bridges old multiplex data into new modules, or adds custom functions without turning the wiring loom into modern art gone wrong.
Ideal for custom dashboards, CAN displays, warning indicators, comfort upgrades, body-control experiments, lighting logic and any electronic visual modification where you need the car to talk properly instead of guessing blindly with a multimeter and hope.
Graphical interface
BEANalyzer UltraPro keeps the workflow visual and practical: live capture, decoded dashboard cards, fixed-row message monitoring, DBC editing, manual transmission, replay tools and BEAN-to-CAN gateway controls are all available from one desktop interface. It is simple enough to use in the car, but complete enough to document real reverse-engineering sessions without going full chaos-terminal mode.
Live workspace
Connect the BEAN serial adapter, capture live traffic, filter frames, highlight changes and keep decoded values visible as dashboard cards. Perfect for quick tests such as opening doors, pressing switches, changing climate settings or watching speed frames update in real time.
Fixed-row analysis
Groups frames by context, DID and MID so each command stays on one stable row. Byte changes are highlighted as they happen, making unknown messages much easier to identify than in a normal scrolling terminal.
Decoder database
Create and maintain the BEAN MPX decoder database directly from the app. Define DID, MID, category, function, ECU candidate, documentation status and JSON signal definitions for values, flags, formulas and notes.
Controlled transmission
Send single or repeated BEAN MPX commands and CAN frames from a controlled panel. It includes bus selection, repetition count, delay control and a transmission log, making it useful for bench testing, isolated modules and adapter validation.
Offline research
Load a recorded CSV session and replay it without the vehicle connected. This turns road tests and bench captures into reusable data, ideal for refining decoder rules, comparing sessions and documenting discoveries later.
Gateway lab
Configure python-can interfaces, Arduino CAN serial bridges and real-time BEAN-to-CAN mappings. This is where decoded BEAN MPX values can become CAN frames for custom dashboards, loggers, retrofit modules and embedded experiments.
Core features
Capture frames in real time with PC timestamp, Arduino timestamp, bus type, frame context, DID, MID, data bytes and raw frame visibility.
Decode known messages into useful values such as speed, outside temperature, warning states, door status, seat belt status and body electronics signals.
Extend the decoder with message names, functions, categories, signals, byte offsets, formulas, bit flags, known values and ECU candidates.
Keep one fixed row per BEAN command or CAN arbitration ID. Watch byte changes highlight in real time instead of chasing endless terminal spam.
Compare previous and current frames, identify changed byte indexes, decimal/hex/binary transitions and the exact bits that moved.
Build a clean live dashboard with selected decoded values and plot numeric signals over time for research, testing and validation sessions.
Save complete capture sessions for spreadsheet analysis, structured research, versioned decoder development and repeatable documentation.
Load previous sessions and analyze them later without the vehicle connected. A single capture becomes reusable research material.
Send individual or repeated BEAN MPX commands and CAN frames for controlled bench testing, module research and development workflows.
Gateway development
BEANalyzer UltraPro can support research workflows where decoded BEAN MPX values are mapped into CAN frames for custom dashboards, loggers, retrofit ECUs, Arduino projects, ESP32 projects and instrumentation modules.
Designed for CANalyst-II, CANable/SLCAN, SocketCAN, PCAN-compatible interfaces, Arduino + MCP2515 bridges and ESP32 TWAI/CAN serial bridges.
Ideal for EasyMultiCAN-based MCP2515 projects and EasyESP32CAN-style TWAI bridges where low-cost hardware needs serious software around it.
Transmission on a live vehicle network must be performed with care. Use isolated modules, bench harnesses and controlled test procedures before touching a complete car.
Hardware adapter ecosystem
BEANalyzer UltraPro is designed to work with an external BEAN MPX adapter through USB Serial. For hardware experiments, sniffers and gateway prototypes, these GitHub libraries are the recommended starting point: BeanMPX for the Toyota/Lexus BEAN side and EasyMultiCAN for MCP2515-based CAN bridges.

Download
The latest available version is BEANalyzer UltraPro v4.18. All platform buttons download that same latest cross-platform package: BEANalyzer_UltraPro_latest.zip. Inside the ZIP you will find the macOS, Windows, Linux and Portable Source folders, so one release file keeps distribution simple and avoids version mismatches. The download endpoint also updates a private server-side counter, so download totals can be checked without exposing them publicly.
