Load datalogs, inspect calibrations, compare BIN files, and get actionable diagnostics and corner-by-corner lap breakdowns.
Five purpose-built tools, each focused on a different layer of the calibration and real-world performance picture — plus a privacy model built for people who don't want their engine data leaving the machine.
Load a datalog from MHD, MHDFlasher, Bootmod3 or MGFlasher 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 eight logging apps — RaceChrono, AiM, Apex Pro, Harry's LapTimer, SoloStorm, TrackAddict, RaceCapture and VBOX. 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 B58 and 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 — your raw engine data stays on your machine and is never sent to the server as part of normal use. Two exceptions, both explicit: BIN files, which need server-side binary decoding, and creating a share link, which uploads a snapshot of that log so the recipient can open it.
No install, no setup. Just sign in and start loading files.
Sign in with your email and password. Sessions persist, so you won't need to log in each visit.
Export a CSV from MHD, Bootmod3 or MGFlasher 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.
