TunerStudio parity

Same INI, same menus, same MSQ.

Menus, dialogs, tables and gauges are built from the ECU definition TunerStudio reads. Tunes load and save as MSQ; logs play back from MLG.

One spec parser

Follows the EFI Analytics ECU definition specification. Pages, byte order, units, expressions, menus, dialogs and [VeAnalyze] come from the INI. Expressions it can't evaluate stay unresolved; nothing is guessed.

Navigation

ECU menus: the INI's own menu tree. Guided: the same settings in first-tune order (vehicle and ECU, hardware, startup and idle, fuel and ignition, auxiliaries).

ECU communication

Web Serial handshake, tune read, live data, write to RAM with a per-value preview and CRC verification. Burn is a separate, confirmed step.

At a glance
