About

Multiecuscan

This advanced diagnostic tool offers dealer-level functionality for Fiat, Alfa Romeo, Lancia, and other select vehicle brands. It allows for fault code reading/clearing, live sensor data visualization, actuator testing, and various reset/programming functions. An OBD interface is required for full vehicle connectivity, though a simulation mode is available.

Highlights
  • Fault code reading and clearing
  • Live sensor data visualization
  • Actuator testing
  • Reset and programming functions
  • PROXI configuration
  • Service reminder reset
  • Generic EOBD diagnostics

Multiecuscan is a dealer level diagnostic tool for most models of Fiat, Alfa Romeo and Lancia vehicles and also covers some models of Jeep, Chrysler, Dodge and Suzuki. We also have support for some Ducati bike models. Please visit our web site for a full list of covered models. The functionality includes: - Fault code reading and clearing - Live sensor data - Live data graphical view - Actuator testing - Reset/programming functions - PROXI configuration - Service Reminder reset - Generic EOBD vehicle diagnostics REQUIREMENTS: An OBD interface is required for connection to vehicles. Without interface it is possible to run connection in "simulation" mode and explore the available functionality. We currently support CANtieCAR v4.x WiFi, CANtieCAR v5.x BLE/WiFi, ELM327 WiFi, OBDLink MX WiFi, OBDLink MX+ Bluetooth, Vgate vLinker WiFi, Vgate vLinker BLE, Vgate vLinker FS/MS Bluetooth interfaces. Please note that some procedures (like PROXI alignment) depend on the interface speed and may not complete successfully with some interfaces. IN-APP PURCHASE: The full functionality of the App requires subscription which can be purchased as in-app purchase. Without subscription the App will run with limited functionality. Please note that the Multiecuscan iOS version is completely separate from Multiecuscan for Windows. The iOS version can be purchased only from the App Store and it is not linked to the license for the Windows' version. It is not possible to transfer license between iOS and Windows. If you already have purchased the full version on another iOS device then click the RESTORE PURCHASES button to activate the full version. NOTE: We are a 3rd party supplier and this is not an official factory tool for the above mentioned brands. The brand names are listed only as reference.

About

3D Topology Optimizer

Features
Read full description

3D Topology Optimizer reduces the weight of a 3D part without sacrificing its strength — entirely on your device, with no cloud upload required. Load an STL model, mark contact surfaces, applied loads (forces and moments), and functionally important faces that must never change. The app then runs a real finite-element simulation and a SIMP topology optimization directly on iPhone, iPad, or Mac to determine which material actually contributes to strength and which can be removed. FEATURES • Automatic hole detection — cylindrical bores are recognized and automatically protected from the optimizer • Calculated entirely on-device — your geometry and load cases never leave your device • High-resolution STL export for 3D printing or CNC machining • Built-in parametric templates (bushings, brackets) to get started without any CAD file • Wireframe and shaded 3D viewer with axis indicators for precise face tagging WHO IT'S FOR Engineers, product designers, makers, and students who design 3D-printed or CNC-machined parts and want a fast, private way to see where material can be safely removed before committing to a print or a machining run. All calculations are a simplified, linear finite-element approximation and do not replace certified FEA software or review by a qualified engineer. Always verify results independently before manufacturing load-bearing parts.

Verdict

The call

The clearest difference is ads: Multiecuscan at none against 3D Topology Optimizer's shown. Multiecuscan also leads on iOS requirement (13.0 vs 17.0). 3D Topology Optimizer's advantage is update cadence (every 6 days vs every 4 months). On price, in-app purchases and device support there is nothing between them.
