How It Works
Three steps to a verified report
Upload your logs
Upload your datalogs to TBK Logs and get them analyzed. Each log gets a health score across five diagnostic categories.
Get scored instantly
Our engine analyzes boost, fueling, ignition, drivetrain, and temperatures. Every finding is weighted by severity and your use case.
Generate your certificate
One click creates a tamper-proof URL. Anyone with the link can verify your vehicle's health -- no account needed.
Why It Works
Why buyers trust verified certificates
Data-Backed Trust
Not just a claim -- real ECU datalog analysis with health scores, category breakdowns, and specific findings. Buyers see exactly what the data shows.
Shareable Link
Every certificate gets a unique URL you can drop into any listing -- BringATrailer, Facebook Marketplace, forums, or a direct message to a buyer.
Tamper-Proof
Every certificate is sealed with a SHA-256 hash at the moment of creation. The data can't be edited after the fact -- what the logs showed is what the buyer sees.
Buyer Confidence
Health scores, category-level breakdowns, mod list, and vehicle profile -- all on one page. Buyers verify independently, no account needed.
Use Cases
Built for every scenario
Whether you're buying, selling, insuring, or tuning — a verified health certificate replaces guesswork with objective data.
Pre-Purchase Inspections
Buying a modified car? Ask the seller for a Verified Health Certificate. If they can't produce one, that tells you everything you need to know.
Selling a Modified Car
Listings with a verified health report sell faster and for more money. Buyers trust data over promises -- drop the link in your BaT, Marketplace, or forum listing.
Insurance Documentation
Some specialty insurers accept data-backed health reports. Prove your modified vehicle is properly tuned and mechanically sound.
Tuner Accountability
Professional tuners can generate verified reports for their clients -- proving the quality of their work with objective data from real datalogs.

Trust is earned with data
Every Verified Health Certificate is generated from real datalog analysis -- not self-reported claims. The verification hash is unique and immutable. If someone shares a TBK Logs certificate link, you know the data behind it is real.
Certificates are publicly viewable. No TBK Logs account is required to verify a report.
