What is TQ/IQ for?
The TQ/IQ section extends an existing Torque-to-IQ map to a higher target torque without changing the map size. The upper torque breakpoints are redistributed and the IQ values are derived from the existing calibration trend.
Required data
- RPM axis from the original map.
- Torque axis in real Nm values.
- Complete TQ→IQ Z-map in physical IQ values.
- Target torque in Nm.
Input format
- Values can be pasted from WinOLS/StageX.
- Tabs, spaces, line breaks and semicolons are accepted.
- Default orientation: rows = RPM, columns = torque.
- If the copied map is rotated, select the transpose orientation.
Calculation
- Paste RPM axis, torque axis and Z-map.
- Set the target torque.
- Select how many upper axis points should be redistributed.
- Calculate and review the result on the right.
Copy output
- New torque axis: new X-axis for the map.
- RPM axis: unchanged speed axis for copy/documentation.
- Z-map: calculated IQ values without axes.
- Full table: RPM/Torque header plus complete map.
- Report: calculation summary.
Check the graph
- The graph compares one RPM row.
- Gray is the original curve, orange is the calculated result.
- Use the RPM selector to inspect individual speed rows.
Important: The tool provides a mathematical working basis. Air mass, smoke limitation, rail pressure, SOI, duration, torque model, gearbox limits and protection functions must be reviewed professionally.
