AEM V3 Water/Methanol Multi-Input Controller Kit (MAP/MAF/IDC)

The AEM V3 multi-input controller kit is the flexible-triggering brain of an AEM water/methanol injection system. It activates flow from any of several inputs - 0-5V, MAF frequency or voltage, injector duty cycle, or an external MAP sensor - making it suitable for both naturally aspirated and boosted applications, including ultra-high-boost setups. The controller has a color-coded harness for easy installation, a system-status LED, and progressive control. Controller kit only.
