Product details
Racers with high compression naturally aspirated engines or boosted engines who are looking for an alternative to boost-dependent water/methanol injection controllers have a solution in AEM's Multi-Input WMI controller. The multiple input design enables users to install AEM's Water/Methanol Injection Kit on both high compression naturally aspirated vehicles (NA) via the MAF/IDC settings and ultra-high boost vehicles (above 40 PSI) using an external MAP sensor. The Multi-Input controller works with an external 0-5v voltage-based external MAP sensor, a frequency-based input for Injector Duty Cycle (IDC), frequency-based mass airflow (MAF), or a 0-5v voltage-based MAF. The Multi-Input controller is offered in three kits; a one-gallon tank kit with a single injector for gas engines (PN 30-3350), a tank-less kit with a single injector (PN 30-3352), and a five-gallon tank kit with two injectors (PN 30-3351) for HD high-output gasoline applications. AEM's Multi Input controller design enables users to install Water/Methanol Injection on high compression naturally aspirated vehicles (NA) via the MAF/IDC settings. The Multi-Input controller works with an external 0-5v voltage-based external MAP sensor, a frequency based input for Injector Duty Cycle (IDC), frequency-based mass airflow (MAF), or a 0-5v voltage-based MAF. The Multi-Input Controller is available with a 1.15-gallon tank (PN 30-3350), a five-gallon tank (PN 30-3351), and a tank-less kit (PN30-3352). Water/methanol injection for gas engines is a proven means for effectively reducing engine inlet air temperatures and suppressing harmful detonation on high compression naturally aspirated (NA) race engines. This allows racers to reliably advance ignition timing-without using high-octane racing fuel-for improved power gains. AEM's Water/Methanol Injection Systems utilize the most robust hardware combined with more advanced features than any other comparably priced water/methanol system.
