Everything your datalog is trying to tell you.

TBK Logs turns raw CSV files into health reports you can actually understand, tracks your car's condition over time, and proves exactly what your mods are doing -- backed by real data.

Health Reports

Upload. Analyze. Understand.

Drop your CSV. In seconds, get a complete health report covering fueling, boost control, ignition, temperatures, and drivetrain -- scored from 0 to 100 with clear green/yellow/red findings. No tuning knowledge required.

Multi-Platform Support

Works with bootmod3, COBB, EcuTek, and any other platform that exports a standard CSV. The parser auto-detects format, handles unit conversions, and normalizes everything.

bootmod3COBBEcuTekAll Others

60+ Parameters Analyzed

Boost target vs actual, WGDC PID behavior, HPFP pressure, lambda tracking, per-cylinder timing corrections, knock detection, superknock, thermal trends, torque interventions, VANOS tracking, and more.

Clear, Non-Technical Breakdown

Every finding comes with a clear explanation -- what's happening, why it matters, and what to do about it. No abbreviations, no guesswork. Like having an experienced tuner review your log and walk you through it.

Mod Impact

Prove what your mods actually did.

Installed an intercooler? Upgraded your HPFP? Changed your tune? Upload a log from before and after, tell us what you changed, and get a data-backed impact report showing exactly what improved -- with real numbers, not feelings.

We know which metrics matter for each mod. Install an intercooler and we highlight IAT, timing, and thermal behavior. Upgrade your HPFP and we focus on rail pressure, fuel delivery, and AFR tracking.

Mod Recommendations

What should I mod next?

Every report ends with prioritized, data-backed upgrade recommendations. Not generic advice -- specific suggestions based on what YOUR log data shows is the weakest link. If your HPFP is dropping, we tell you. If your intercooler is heat soaked, we tell you. If your tune needs revision, we tell you.

Each recommendation includes expected impact, estimated cost range, and confidence level. Up to 5 ranked suggestions per report, with category tags showing which part of the analysis triggered it.

Compare Logs

See what changed between any two logs.

Select any two logs from your history and get a side-by-side comparison. Health scores, key metrics, and chart overlays with both pulls aligned on the same time axis. A detailed summary explains what improved, what got worse, and what stayed the same.

Score comparison with category-level breakdown. Key metrics table with color-coded deltas. Overlay charts with both pulls on the same axis -- boost, HPFP, timing, temps, and torque aligned to WOT start.

Health Tracking

Track your car's health across every log.

Your dashboard shows a health score timeline -- every log plotted chronologically so you can see if your car is trending healthier or degrading. Spot issues before they become failures.

Platform Support

Any platform. Any format.

Every tuning platform logs data differently -- different column names, different units, different conventions. TBK Logs normalizes all of it automatically, regardless of source.

bm3 logs fuel trims as ratios, MHD logs them as percentages, Ecutek also uses percentages -- we normalize everything.

MHD's IAT means pre-turbo air while bm3's IAT means post-intercooler air -- we know the difference.

Ecutek logs boost in hectopascals, HPFP in megapascals, and lambda as a ratio instead of AFR -- we convert it all.

JB4 exports use a different channel layout and naming scheme -- the same parser handles it. Platform is just a format detail.

If your platform logged it, we use it. If a parameter wasn't included, we tell you exactly what to add to your logging config next time. See all supported platforms.

Glossary

Don't know what WGDC means? We've got you.

Our glossary explains every single metric in clear, simple language -- what it is, why it matters, what healthy looks like, and which platforms log it. Built for beginners, useful for experts.

Browse the full glossary or see a demo report to see these metrics in action.

Vehicle Profiles

Context-aware analysis.

Your vehicle profile -- engine, tune level, fuel type, turbo, intercooler, fuel system mods -- informs every threshold in the analysis. A stock B58 on pump gas has different healthy ranges than a Pure 800 on E50 with port injection.

Support for multiple vehicles. Edit your profile anytime. Previous reports keep the profile that was active when they were generated.

Quality of Life

Built for Real Use.

Small things that make a big difference when you're logging every week.

Log Notes

'Tag any log with a note -- 'first pull after downpipe', 'hot day at the track', 'tuner asked me to log this.' Notes show up on your dashboard, in reports, and in shared links.

Bulk Upload

Drop up to 10 CSVs at once. They queue up and analyze one by one -- each gets its own report. No more uploading one file at a time.

PDF Export

Download any report as a clean, branded PDF. Send it to your tuner, attach it to a forum post, or keep it for your records.

Multiple Vehicles

Own more than one car? Add multiple vehicles to your profile, each with its own mod list and log history. Switch between them on upload.
