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. An optional exhaust gas
temperature (EGT) probe is one example of an optional accessory that
will be offered by Edge. Look for a variety of other optional
accessories to become available in the near future.
