Overview

Extend Torque-to-IQ maps professionally

In many diesel calibrations the result is not limited by a single map. Torque-to-IQ maps connect requested torque with injection quantity and are an important part of the complete torque model.

The ECU-Jobs TQ-IQ Tool helps professional users import existing TQ→IQ maps from WinOLS or StageX, extend torque axes deliberately and derive new IQ areas from the original calibration trend.

ECU Jobs is not a file service provider and does not create tuning files. This tool page adds a technical resource for tuners, calibrators and file service providers using the ECU Jobs marketplace.

Professional Calibration Utility

Free Torque-to-IQ Extension Assistant for Diesel ECU Calibration

The ECU-Jobs TQ-IQ Tool is a free professional calibration assistant for diesel ECU tuners, calibration engineers and automotive software developers. It is designed for workflows where torque axes, RPM axes and complete TQ→IQ maps need to be extended in a structured way.

Instead of shifting upper torque ranges manually in spreadsheets, users can paste existing map data, define a target torque and redistribute upper breakpoints. Lower axis areas can remain protected so valuable stock resolution is not unnecessarily lost.

The focus is traceable calibration work: smooth, monotonic and plausible extrapolated results that must still be reviewed in the context of the complete torque model, air system, injection system and engine protection strategy.

Torque Axis Extension

Extend torque axes without changing map size

In many projects the upper torque area needs to be extended without changing the existing map dimensions. The tool helps restructure existing breakpoints so new target torque values can be covered.

Lower and sensitive axis areas can be preserved while upper torque points are redistributed. This creates a better technical basis for Stage 1, Stage 2 or hardware-related diesel calibration.

The extension is deliberately positioned as assistance. It does not replace professional review, but it reduces repetitive spreadsheet work and makes axis and map changes easier to understand.

IQ Extrapolation

Derive IQ values from the original calibration trend

The tool extrapolates new IQ values based on the existing map trend. Extended areas can therefore be prepared more consistently than when individual cells are filled manually without context.

Different development goals can use conservative, balanced or more aggressive extrapolation strategies. A target IQ at a specific RPM and target torque can also be used as an extrapolation anchor.

The intended result is a smooth and monotonic TQ→IQ extension that can be reviewed, adjusted and validated in professional calibration environments.

Frequently asked questions about the ECU-Jobs TQ-IQ Tool

What is the ECU-Jobs TQ-IQ Tool?

The ECU-Jobs TQ-IQ Tool is a technical workflow aid for diesel calibrators. It supports Torque-to-IQ map extension, torque axis restructuring and trend-based IQ extrapolation.

What does TQ→IQ mean?

TQ→IQ describes the conversion from requested torque to injection quantity. These maps are part of the torque model in many diesel ECUs and need to be reviewed consistently during professional calibration.

Can the tool work with WinOLS or StageX data?

Yes. The page is designed around workflows where RPM axes, torque axes and complete TQ→IQ maps are copied from WinOLS or StageX and processed further.

Does the tool automatically create finished tuning files?

No. The tool does not create finished tuning files and does not replace professional calibration work. It supports recurring calculations and provides a structured working base.

Which extrapolation strategies are planned?

The tool is described for conservative, balanced and more aggressive extrapolation strategies. A target IQ at a specific RPM and torque point can also be used as an anchor.

Is the download available?

Yes. The ECU-Jobs TQ-IQ Tool is available as a free ZIP download and can be downloaded directly through the download button on this page.

Who is the tool for?

The tool is intended for professional ECU tuners, diesel calibrators, WinOLS and StageX users, file service providers and automotive software developers.

Is ECU Jobs a calibration provider?

No. ECU Jobs is a marketplace for file service requests and professional providers. The TQ-IQ Tool is a technical resource for professional calibration workflows.
