Secara umum ISC merupakan rangkaian elektronik yang fungsi utamanya adalah mengatur jumlah udara yang akan melalui idle port pada saat katup gas posisinya tertutup. Hal ini berbanding terbalik dengan komponen seperti IMAS dan ISAS terdahulu di mana pengemudi harus mengatur putaran idle di mesin secara manual.
It is however an aspect that is often overlooked or incorrectly tuned, leading to unstable idle and stalling. In this webinar we'll discuss what you need to know to get a rock solid idle, what hardware is required, and how to approach the tuning on the ECU Master EMU Black. 00:00.
Pengertian Idle Speed Control (ISC) ISC (Idle speed control) atau disebut juga IAC (Idle air control) merupakan rangkaian elektronika yang digunakan untuk mengatur banyak sedikitnya udara yang melewati idle port ketika katup gas dalam posisi tertup. Sistem ISC, digunakan pada mesin EFI sebagai pengganti sekrup idle speed yang diatur secara manual.
Last Updated on Mon, 04 Dec 2023 | Toyota Engine Control. The idle speed control program is based on an ECU stored look up table which lists pintle step positions in relation to specific engine rpm values. Over time, engine wear and other variations tend to change these relationships.
The idle air control valve controls the air needed to maintain a steady idle speed. It essentially acts as a bypass of the throttle body plate. The solenoid in an idle air control valve can get
The idle speed control mode is used to prevent engine stall during idle. The goal is to allow the engine to idle at as low an RPM as possible yet keep the engine from running rough and stalling when power-consuming accessories, such as air-conditioning compressors and alternators, turn on.
The main objective of the idle speed control is to maintain the idling speed at 650rpm and to reject as quickly as possible the extra load exerted on the engine system during idling mode. Comparing the three methods, it shows that PID tuning by ILA produced better results than heuristic tuning and pole placement.

The ISC (Idle Speed Control) system is provided with a circuit that bypasses the throttle valve, and the air volume drawn in from the bypass circuit is controlled by the ISCV (Idle Speed Control Valve). The ISCV uses the signal from the engine ECU to control the engine at the optimum idling speed at all times.
An idle air control actuator or idle air control valve ( IAC actuator / valve) is a device commonly used in fuel-injected vehicles to control the engine's idling rotational speed ( RPM ). [1] In carburetted vehicles a similar device known as an idle speed control actuator is used. Description
