What You Get

Everything You Need to Read a Log

Spoolin is a specialized AI trained on BMW, Toyota, Nissan, Infiniti, Honda, and Acura tuning data — not a generic chatbot. It knows what good numbers look like for your platform.

Full Log Analysis

Structured report covering boost, timing, AFR, IAT, load, and fueling — with flags for anything out of range. Choose Quick Mode for results in under 30 seconds or Deep Mode for enhanced reasoning that surfaces subtle trends a quick pass might miss.

Knock & Safety Flags

Automatically detects timing retard events, knock counts, wastegate duty cycle concerns, and any parameter trends that warrant attention before your next pull.

Follow-Up Conversations

Keep the conversation going. Ask Spoolin to explain specific RPM ranges, dig into cylinder-by-cylinder timing, or prep questions for your tuner. Context from your log stays live throughout the session.

Interactive Graphs

Ask for a boost vs. RPM graph, timing by cylinder, AFR across the pull — built directly from your uploaded data. No external tools required, no copy-pasting.

Visualize

View all your log parameters on a single unified graph with multi-parameter visualization. Select any combination of parameters and overlay multiple logs to track performance evolution across tune revisions.

Log Comparison

Compare a new log against a previous session to see exactly what changed between tune revisions or hardware updates — boost delta, timing shift, AFR movement, all in plain language.

Performance Analytics

Track your tune progression over time. AI Insights summarizes what improved or regressed between sessions, and a ranked leaderboard shows your best pulls across all logged data.
