ECU torque model: Driver Wish, Torque-to-IQ and limiters

TECHNICAL CONTEXT
What matters for this topic.
Modern engine control units use a torque chain rather than working directly in horsepower. Driver Wish converts pedal position into requested torque. Torque limiters, protection functions and transmission permissions determine how much of that request is actually allowed.
On many diesel ECUs, Torque-to-IQ links permitted torque to the required injection quantity. Related models reconcile air mass, boost, rail pressure and injection duration. Raising isolated maps makes the chain inconsistent: the ECU may limit internally, calculate implausible load or request unsuitable fuel quantity.
A coherent calibration follows the path from Driver Wish through every relevant limiter to Torque-to-IQ and the smoke limiter. Axes, units and scaling must match the software version, while ECU and TCU torque values should remain aligned. Versioning and delta comparisons keep each change traceable.
