Load datalogs, inspect calibrations, compare BIN files, and get actionable diagnostics and corner coaching.
Five purpose-built tools, each focused on a different layer of the calibration and real-world performance picture.
Load MHD CSV exports and explore your engine data with synchronized, multi-channel Plotly charts. Automatic WOT pull detection, gear tracking, and optional DME table overlays to correlate what the ECU is commanding against what the engine actually did.
Nine analysis engines run against your datalog and BIN to surface actionable diagnostics. Inspect fuel scalar correction, WGDC base / P-factor / D-factor behavior, ignition timing, EGT protection activity, thermal proximity, and a full tune health checklist with MG1 torque recommendations.
Upload two calibration BIN files and diff them table-by-table. Changes are color-mapped on a blue-to-red diverging scale so increases and decreases are immediately visible at a glance — no manual spreadsheet comparison needed.
Import telemetry from seven different logging apps — RaceChrono, AiM, Apex Pro, Harry's LapTimer, SoloStorm, TrackAddict, and more. Auto-detects the format, identifies corners, computes sector times, and overlays engine operating points for track-day debriefs.
Dive into the BMW MG1 torque fill architecture — the most complex layer in the S58 calibration. Inspect 11 filling flags and 26 torque limit bits, with per-cell headroom analysis against your own BIN so you can see exactly which limits are the binding constraint.
CSV datalogs are parsed entirely in the browser and never transmitted to the server. Your raw engine data stays on your machine. Only BIN files, which are required for server-side binary decoding, are temporarily uploaded to the session.
No install, no setup. Just sign in and start loading files.
Use your access password to authenticate. Sessions persist so you won't need to log in each visit.
Export a CSV from MHD+ and drop it on the Viewer. Charts render immediately with all channels available.
Add your calibration BIN file to unlock the Analyzer, Compare, and MG1 Limits tabs with full table data.
Run the Analyzer to get flagged issues and recommendations, or diff two BINs to review what changed.
