Ford Super Duty High Idle and Idle Shutdown Bypass<\/h2>\n

Idle Shutdown Bypass + High Idle Control
\n<\/em>Never let Ford’s 30-minute idle shutdown interrupt your work again.<\/strong><\/em><\/p>\n

Idle On! PLUS gives you complete control over your Ford Super Duty while it’s on the job.<\/p>\n

Not only does Idle On! PLUS eliminate Ford’s factory 30-minute idle shutdown, it also adds selectable High Idle capability to help support increased electrical demands and work equipment operation.<\/p>\n

Designed for 2023 and newer Ford Super Duty F-250 through F-600 trucks, Idle On! PLUS uses Ford’s factory SEIC (Stationary Elevated Idle Control) system to provide a simple, reliable, and non-invasive installation.<\/p>\n

With the parking brake engaged, simply activate your switch during the first 20 minutes of idling to enter High Idle mode.<\/p>\n

<\/strong>High Idle RPM<\/strong>:
\nDiesel: Approximately 1160\u20131200 RPM
\nGas: Approximately 960\u2013980 RPM<\/p>\n

Whether you’re powering emergency equipment, charging batteries, running inverters, operating hydraulic systems, or simply wanting increased idle performance, Idle On! PLUS helps your truck work harder for you.<\/p>\n

Installation requires no cutting or splicing of factory wiring, no computer programming, and no permanent modifications. The system is fully removable and designed to work with your truck’s existing systems while helping preserve your factory warranty.<\/p>\n

Do I need factory upfitter switches?<\/h3>\n

No. PLUS works with or without factory upfitter switches. A switch is used to select high idle; follow the installation instructions for your wiring option.<\/p>\n

Does it require an ECU tune?<\/h3>\n
