Upgrade your YS480 or YS640 to the new Adaptive Control System (ACS) control board. These kits contain all necessary pieces to update your existing YS480 or YS640 pellet grill and begin using the YS Drive App (iOS and Android compatible).

The new ACS control board with Wi-Fi is a cloud based system powered by FireBoard. It allows you to connect to your pellet grill via Wi-Fi or Bluetooth technology. This means you can control your grill's temperature from anywhere. Two integrated 6' food probes allow you to monitor the temperature of your food without lifting the lid.

Beyond connectivity, the new ACS control board is built around a powerful microprocessor that understands multiple input variables. What does this mean for the user? It means access to an intuitive control board that is always learning and improving. It means quicker temperature recovery after opening the lid or loading up the cooker with meat. Smarter, robust features, and better performance. It's a no-brainer.

Why upgrade to ACS? 

• Allows you to use YS Drive App to control pellet grill
• Control your grill's temperature from anywhere
• Monitor food temps from app
• Intuitive control board is always improving
• Faster temperature recovery

*YS480 or YS640 pellet grills built before May 2015 require the thermocouple relocation kit. Please double-check build date before ordering.

Add the Full Performance Upgrade Kit to receive the redesigned high-airflow burn grate and the ceramic igniter to complete the experience.

The ceramic igniter heats up twice as quickly and creates heat with no direct igniter contact, which means your igniter will last much longer and stand up to heavier use.

The burn grate has been redesigned with several crimps in the burn grate that will prevent it from warping with heat. This will eliminate the need to occasionally reshape the burn grate. Furthermore, the air flow has been redesigned to more efficiently direct heat for EVEN BETTER consistent heating across the cooking chamber.
