📄️ Cranking Idle Air Control
A smooth engine start requires there to be an adequate amount of air for the supplied quantity of fuel. Ideally the idle air control (IAC) valve will supply enough air for the car to crank without the driver needing to press the accelerator.
📄️ Cranking RPM Limit
The cranking RPM limit informs the ECU to transition out of cranking mode once the engine RPM exceeds the set limit. Typically values in the 350-450 RPM range are reasonable values.
