Diagnostic Device

The Universal CAN Bus Engineering Tool


A high-performance, customizable diagnostic device designed for any CAN Bus architecture. StartDiag features dynamic PID dashboards and the power of open-source LUA scripting, allowing users to execute complex CAN Bus requests and develop bespoke diagnostic logic for automotive applications.

Power demands expertise. Welcome to the club of those who prefer to understand what’s happening on the CAN bus rather than pressing an ‘auto-repair’ button that tells you nothing.

Open-Platform Flexibility

We provide the platform; you provide the vision. Use the open LUA language to build proprietary solutions without being restricted to predefined approcheas.

Pro-Grade Hardware

Built with the same reliability and precision that has defined TomElectronics Srl for over 20 years (Smarty Performance King and MM3).

Plug & Play + DIY

Ready to use out of the box for standard monitoring, yet infinitely expandable for developers and enthusiasts.

Monitor.
Script.
Control.

Your Bridge
to Advanced
Diagnostics.

StartDiag is not just a diagnostic tool—it is a high-performance, open-architecture platform designed for those who demand total control over CAN Bus communication. Whether you are an automotive engineer, a professional tuner, or a DIY developer, StartDiag provides the hardware and software freedom to interface with any CAN-enabled system.

Dynamic Data Visualization

Stay on top of every parameter with fully customizable PID Dashboards.

  • 1: Monitor real-time data with high-definition clarity.
  • 2: Configure layouts to show only the telemetry that matters to your project.
  • 3: High-speed data logging for deep-dive analysis.

The Power of LUA Scripting

Break free from "closed" diagnostic systems. StartDiag features a built-in LUA Scripting Engine, allowing you to:

  • Execute Custom Requests: Write and run your own scripts to query specific CAN Bus IDs.
  • Automate Routines: Create complex diagnostic sequences that run automatically.
  • Bespoke Logic: Develop unique control functions tailored to your specific hardware or vehicle platform.

Universal CAN Bus Architecture

While our roots are in the automotive world, StartDiag is built for the broader ecosystem.

  • Automotive: Full compatibility with modern vehicle control modules.
  • Industrial & Beyond: Engineered to interface with any system utilizing CAN Bus protocols (marine, agricultural, or industrial automation).

StartDiag: Customizable CAN Bus Diagnostic Platform

StartDiag is a high-performance, modular diagnostic device engineered for 12-volt vehicles equipped with OBD-II, EOBD, or WWHOBD (CAN Bus) connectors. Designed for both professional engineers and automotive enthusiasts, it offers a unique "Open Platform" approach, combining real-time data visualization with the power of custom LUA Scripting.

Key Features

  • Customizable Dashboards: Features 4 independent dashboards (A, B, C, D), each supporting 6 different layouts and various gauge types (analog/digital).
  • Real-Time Monitoring: Display PIDs directly from the CAN Bus with built-in alarms, peak value tracking, and error code reporting per gauge.
  • LUA Scripting Engine: Execute custom CAN Bus requests and automate diagnostic routines using standalone LUA scripts directly from the microSD card.
  • Advanced Data Analysis: Includes a built-in CAN Logger for high-performance traffic inspection and a PID Chart view to track data trends over time.
  • Smart Filtering: Implements an Exponential Moving Average (EMA) filter to smooth "flickering" data for a more stable and professional reading.
  • DTC Management: Read and clear Diagnostic Trouble Codes (DTCs) with customizable, user-editable descriptions stored on the SD card.
  • StartDiag PC Suite: Comprehensive PC Suite – Fully Included. StartDiag is designed to put you in the driver’s seat. That’s why we provide our full-featured PC Suite at no extra cost. Unlike other diagnostic tools that lock features behind paywalls or monthly licensing fees, we believe in giving you complete control from day one. When you purchase the hardware, you get the entire software ecosystem included—forever.
