MK EOI Free Tool — Diesel Injection Timing and SOI Generator
This specialized engineering utility developed by MK ECU Logic is designed for analyzing and optimizing diesel injection timing. It accurately calculates the End of Injection (EOI) based on user-defined Start of Injection (SOI), rail pressure, and duration maps, making it an essential tool for precise ECU calibration and custom diesel tuning.
Highlights
Supported Hardware
Functions as a standalone map calculator and data analyzer. It is fully compatible with raw map data extracted using any standard ECU programming and tuning software (e.g., WinOLS, ECM Titanium).
Supported Languages
English.
Package contents
Compatibility notes
Works seamlessly with raw map data values (RPM, IQ, Rail Pressure, Duration) from various diesel engine control units. Ensure that the correct conversion factors and offsets are applied within the tool to guarantee accurate EOI calculations.
Basic usage
Operating systems
Windows 10 and Windows 11.
Minimum system requirements

Highlights
- Analyze Start of Injection (SOI), rail pressure, and duration maps
- Calculate End of Injection (EOI) ATDC for specific operating points using RPM and IQ
- Generate targeted SOI maps based on desired EOI parameters
- Apply custom scaling, factor, and offset values to map data for precise conversions
- Export operating point reports to TXT and generated SOI maps to CSV

Basic usage
- Paste your SOI, Rail Pressure, and Duration map data into the corresponding fields in the "Map Data" tab.
- Set the appropriate axis orientations (Rows/Columns) and apply necessary scaling factors.
- Navigate to the "Operating Point Analyzer" to calculate specific injection parameters for a given RPM and IQ input.
- Use the "Target EOI -> SOI Generator" to automatically calculate a new required SOI map for a desired target EOI.
- Export the generated map data to CSV or TXT for integration into your primary ECU tuning software.
