ECU Tools

Convert ECU hex values (e.g., 0x1A) into human-readable decimal format for easier map interpretation and editing.

Calculate additive or XOR-based checksums from ECU firmware bytes to help validate edited files before flashing.

Visualize ignition, fuel, or boost maps as color-coded grids using pasted hex or decimal input. Includes axis labels, stats, and export features.

Extract structured ECU tables from raw pasted bytes. Configure axis labels and export as CSV or JSON.

Select a region of bytes and shape it into a labeled table, then preview or export to Map Viewer.

Scan raw hex or binary files to automatically locate table-like regions within ECU data.

Load, inspect, and modify raw ECU binary data byte by byte. Useful for identifying map regions and checksum locations.

Edit a mock ECU map table and simulate output effects. A hands-on tool for learning how value changes impact tuning.

Decode Vehicle Identification Numbers to reveal manufacturer data and model year information.

Apply JSON-based ECU map definitions to your firmware and open maps instantly.

Apply percentage-based scaling or fixed offset changes to ECU maps. Automatically clamps values between 0–255 for 8-bit compatibility.
