The EGT probe is a sensor that allows users to monitor critical Exhaust Gas Temperatures to ensure added power is not creating excessive heat which, in turn, can cause engine damage. With the EAS system a user can connect multiple EGT sensors to monitor temperatures in different locations and compare readings to be even more precise.
The Edge Accessory System (EAS) was created with future expandability in mind. The architecture of the EAS allows users to connect multiple accessories, daisy-chain style, to the CS and CTS platform. The ability to daisy-chain multiple accessories using the EAS allows users to monitor and display dozens of parameters on a single device.
EAS Starter Kits are only available to work with the CS and CTS product lines. In order to use the EAS accessories you must have an EAS Starter kit (part # 98620).
