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 Evolution CS or CTS. This means Edge can create optional accessories that can be added to the products by the owner at any time. For example you can add an optional exhaust gas temperature (EGT) probe, pressure sensors, turbo timer, temperature sensors and many more optional accessories that will be offered by Edge as they become available in the near future.
