Ibasaka Posted January 19 Report Share Posted January 19 Hi All, I have a Toyota 3 wire ISC valve (OEM 4AG 20V) wired into aux 1/2 on a MonsoonX. It is wired in the following manner: AUX 1 -> RSC (Rotary SW Close) B+ -> 12V AUX 2 -> RSO (Rotary SW Open) The issue I am encountering is that the rpm begins to rise to 1500 from 950ish and idle hunt as the car warms up. I am able to mitigate the hunting and bring the car back to a steady 950-1k idle by going into the idle speed control settings and activating "Test Aux 1" which I am assuming closes the ISC valve. Please advise. Base map is attached below. 4age 20v 1-17-23.pclx Quote Link to comment Share on other sites More sharing options...
