Everything You Need

Professional-grade tools for ECU calibration, map editing, and ROM analysis — all in one application.

Full A2L Parser

Complete DAMOS/A2L support with RECORD_LAYOUT parsing — automatic data size, signedness, axis types (STD_AXIS, COM_AXIS, FIX_AXIS), and COMPU_METHOD scaling.

Map Overlay Editor

Waverform style visualization with 2D table, 3D surface view, heat maps, original vs. modified comparison, and inline editing. 8/16/32-bit signed & unsigned.

2D Waveform View

Visualize the entire ROM as a waveform with color-coded map blocks. Click any region to open it. Navigate thousands of maps at a glance.

ROM Linking

Link modified ROMs to A2L-referenced originals with automatic pattern matching and confidence scoring. Compare any two versions side by side.

Format Support

BIN, HEX (Intel), S19 (Motorola), ORI, BBF, MOT files. Full hex editor with configurable cell size, byte order, and display format.

AI Translation

One-click AI translation of Bosch German map names and descriptions to English, Spanish, Chinese, or Thai. Full UI localization.

Version Control

ROM snapshots as named versions. Compare any version against stock. Roll back changes safely. Never lose your work.

Map Packs

Export and import tuning changes as portable map packs. Apply across different ROM versions with automatic address matching.

AI-Powered Tuning

The first ECU software with an integrated AI assistant. Tell it what you want, it finds the maps and makes the changes. Supports all APIs (Claude, OpenAI, Grok, Deepseek, Qwen, etc...)

RX14 AI Assistant — Claude
You > Do a cat off on this ROM
AI > I'll search for catalyst monitoring maps...
▸ search_maps("DKAT*")
▸ search_maps("KAT*")
Found 3 catalyst maps:
• DKATMAX (16×12) — Max catalyst efficiency threshold
• DKATMIN (16×12) — Min catalyst efficiency threshold
• KATSRT (1×1) — Catalyst start temperature
▸ zero_map("DKATMAX") ✓ 192 cells zeroed
▸ zero_map("DKATMIN") ✓ 192 cells zeroed
Catalyst monitoring disabled. DTC P0420/P0430 will no longer trigger.

 Common Operations

Decat / Cat Off
DKAT*, KAT* → zero monitoring thresholds
DPF Delete
DPF pressure & soot maps → disable regen
EGR Off
AGR* valve position → zero EGR flow
Pops & Bangs
Overrun fuel cut + ignition retard
Speed Limiter
VMAX maps → raise or remove limit
Boost Increase
LDRXN* → raise boost request maps
Rev Limiter
N_LIMIT → raise RPM cutoff
Launch Control
LC torque + RPM threshold maps

Supported ECU Platforms

Works with all major ECU families via A2L files. Automatic base address detection for 24-bit and 32-bit architectures.
