We recently acquired the inventory of a large marine parts distributor. May have cosmetic blemishes from storage.

The STW ESX2-4 is a rugged, freely programmable electronic control unit designed for demanding mobile and marine applications. These modules support custom control strategies and can be reprogrammed to meet specific system requirements. New or previously configured units can be erased and reprogrammed, allowing integration into custom applications. In some cases, OEM-supplied firmware may be locked, but a full reflash with new software is still possible.

Please Note: This unit may require reprogramming before use and due to the complexity we are unable to conduct a full bench test to verify its complete functionality. Therefore, we offer the buyer a 30-day period to thoroughly test the item. If it does not function properly during this time, they can return it for a full refund.
