*Attention!* This is a Computer-Controlled Charging System

• This vehicle uses a factory computer (ECU/PCM) to control charging voltage, so voltage will continue to follow the factory system behavior.
• This high-output alternator still provides the increased amperage you purchased, delivering stronger performance under load and faster battery recharge
• Custom or fixed voltage output will require ECU tuning.
