Product Description

2-Wire Remote Mount Idle Speed Control Solenoid Kit

 

  • Requires only one ECU output
  • Universal remote mount with various options of fittings available

 

Idle speed control is an important aspect of any engine management system. On engines with a mechanical cable-type throttle body, when the throttle is closed, a precisely controlled amount of air must be bypassed around the throttle butterfly to allow the engine to maintain a smooth and constant idle for various loads and engine temperatures. The ECU controls a type of  valve to let this air into the intake manifold.

 

Idle control valves come in various forms including 2-wire solenoids, 3-wire solenoids and stepper motors (usually 4 or 6-wire). It is important to consider the capabilities of the ECU when considering which type of idle control valve to use. With many entry level ECU’s that have a limited number of inputs and outputs available, sacrificing 2 or more ECU outputs to control either a 3-wire idle valve or an idle stepper motor is not an option. Furthermore, due the increased complexity (and therefore, cost) of supporting stepper motor idle control, certain entry level aftermarket ECU’s only support the simpler idle solenoids. Common examples of ECUs that we encounter that fall into this category include the Link G4+ Atom and Monsoon ECUs. While all other Link G4+ wire-in ECU’s support stepper motor idle control, only idle speed control solenoids can be used with the Atom or Monsoon.

 

This 2 wire idle air control valve requires a +12V ignition feed and a single pulse width modulated (PWM) low-side driven signal from the engine control unit (ECU), which progressively controls opening of the valve. An internal spring is used so that no valve closing signal is required from the ECU.  As a result, only one ECU auxiliary output is required. The solenoid included in the kit bolts to the CNC-machined aluminium adaptor that can be remote mounted where required.

 

The kit includes:

 

  • 2-wire idle speed control solenoid (a.k.a. ISC Valve, IAC Valve)
  • 2-pin electrical connector with terminals and seals
  • Solenoid gasket
  • CNC-machined remote mount aluminium adaptor
  • Inlet and outlet fittings – Choice of 20mm straight barb, 90 degree barb or AN-10 male fittings
  • Mounting hardware

 

For plumbing the idle control valve, common 19mm (3/4″) heater hose is a readily available and affordable option, however note that the section of hose on the intake manifold side of the valve is exposed to engine vacuum which can suck the hose shut, especially when this section of hose is long. Therefore, we recommend using braided AN-10 hose between the manifold and valve to ensure that the hose does not cause a restriction to air flow. Accordingly, AN-10 male fittings are available with this kit as an option.

 

Recommended signal frequency = 120Hz

 

Port furthest from connector is to be plumbed to the intake (vacuum) side
