Engine Calibration Intelligence
Professional ECU firmware analysis and calibration platform.
Bosch, Siemens, Delphi, Denso and Valeo — all in one tool.
Three Steps. Zero Complexity.
Upload Binary
Drag and drop your .bin firmware file. The platform auto-detects ECU type, software version, and vehicle match within milliseconds.
Select Solutions
Browse available calibrations for your ECU. Each solution uses anchor-based detection — works across firmware versions automatically.
Apply & Export
One click applies all selected modifications with dual codeblock support. Automatic checksum correction included. Ready to flash.
Built for Professionals
Map Viewer & Editor
View and edit fuel, boost, timing, limiter and sensor maps. 2D/3D visualization with configurable axes and engineering units.
Automatic Solutions
360+ pre-built calibration modules. Anchor-based address detection works across firmware versions. No manual hex editing.
Binary Comparison
Side-by-side diff between original and modified files. Every changed byte highlighted with map context.
Auto-Detection
Instant ECU identification by software number, file size and byte signatures. Automatic map address resolution.
Checksum Correction
Built-in algorithms verified byte-by-byte. Files ready to flash via OBD or bench — no third-party tools needed.
DTC Scanner
Scan firmware for active DTC codes. Manage error codes directly in the binary with P-code descriptions.
Available Solutions
One-click automated calibration modules. Select, apply, export. Every solution is validated per ECU family with anchor-based detection.
Stage 1
Optimised fuel and boost maps. +15-25% power with stock hardware.
Stage 2
