Features
AllDataLogs keeps the datalog itself the focus — fast, precise, and readable, whether you’re on a shop PC or on your phone at the track.
Open HP Tuners HPL — on any device
Open .hpl logs and convert them to CSV right in the browser, with no HP Tuners software. The only viewer that opens HPL directly on your phone.
Synchronized multi-channel charts
Stack channels on time-synced upper/lower panels with independent per-channel scaling and a shared crosshair.
Scrubber & precise cursor
A bottom overview scrubber with a draggable zoom window, plus arrow-key stepping and zoom for frame-accurate inspection.
Live channel values
Every channel shows its value at the cursor even before you plot it — search, sort, and assign channels fast.
Robust CSV import
Handles real-world HP Tuners and other exports: delimiter and units auto-detection, duplicate columns, and categorical channels.
Race Time — set your zero point Pro
Drop a zero point anywhere in a log — a launch, a spool-up, a shift — and read every channel relative to that moment. Built for analyzing pulls.
Compare runs Pro
Line up multiple HP Tuners pulls side by side to see exactly what changed between tunes.
Save & sync Pro
Save viewer configurations, channel mappings, and vehicle presets to your account and open them from any device.
Export & advanced controls Pro
Export converted or processed data and unlock advanced chart controls.
Presets & gauge layouts
Channel-role normalization drives vehicle-aware presets and gauge clusters (expanding over time).
