Bimmer Code Tool

The Bimmer Code Tool analyzes a BMW model, year, and target module to propose safe ECU feature changes. It produces a structured change plan, an estimated coding time, and a risk score to guide technicians and informed hobbyists. Conceptually, it encapsulates BMW coding rules, module dependencies, and firmware considerations into a testable plan before any hardware interaction. The tool emphasizes safety, warranty awareness, and auditable decision logs. It supports scenarios such as enabling optional features or disabling nonessential ones while avoiding irreversible steps without confirmation. Practical use cases include tuning infotainment options, adjusting driver-assistance presets, or toggling hidden settings within allowable regions. Unique value arises from explicit compatibility checks, scenario-specific risk scoring, and exportable change snapshots that aid audits and traceability. It serves both professional shops and capable hobbyists seeking repeatable, defensible coding guidance. Output artifacts include a change_set, rationale notes, and an execution plan suitable for review with vehicle diagnostics hardware.
