BEFORE YOU GET STARTED
Clear capabilities. Clear requirements. Choose the workspace with the right expectations.
The ECU Guide workspace brings together the connection library, file and log inspection, comparisons, garage, customers, work orders, reports, tutorials, tool directory, case history, U.S. vehicle research and backup tools. The planned price is $59 as a one-time ECU Guide purchase. Pre-registration is free; sales are not open yet. Hardware and licenses for independent programs are separate.
Both independent shops and hands-on owners can use the workspace. Guided views and tutorials explain the controls, channel mapping and workflow. You still need to confirm your logger’s units, match the exact ECU and understand the limits of your measurements. The software does not replace vehicle-specific training or testing.
Yes. You can inspect a supported CSV/TSV log on its own, or submit an original ECU file together with the log. Confirm the channel mapping and units before analysis. The quality of the findings depends on what your sensors and logger actually recorded.
It helps you inspect recorded values, differences from available targets, flagged events and missing evidence. AI explanations can help you interpret that analysis when configured. Findings are starting points for investigation, not proof of a cause.
The AI assistance feature is part of the workspace. In this offer it requires a configured AI service, and provider usage is billed separately. The $59 purchase does not automatically fund API credits or provide unlimited AI calls. Log statistics, charts and comparisons work without AI.
Check the exact ECU, processor, software version, log format and independent tool requirements. The tool directory includes GM and Subaru projects, but coverage varies by vehicle and software. A brand name in the library does not mean every U.S. model is supported. Use the searchable preview before choosing the product.
No. Reading or flashing a physical ECU requires a compatible external application, interface and vehicle-specific process. The tool directory explains where to research independent projects; those projects remain available from their authors under their own licenses.
Yes. Record the complaint, tests, findings, work performed and next steps in a work order. Add photos and your workshop details, then export the report as a standalone HTML file or use the browser’s print function to save a PDF.
