Product Review

AEM's Boost Dependent HD turbo Diesel Controller has an on-board MAP sensor (up to 40 PSI) with a molded-in nipple for a boost hose pickup. The controller design features large, turn-resistant knobs and larger numbering to easily set accurate start and full activation points, with covered status LED and test buttons for added splash resistance. A plug is integrated into the controller housing for mating to the redesigned wiring harness's positive-lock connector. The Boost Dependent controller housing includes a wiring legend on the back, easy to access integrated fuse and molded mounting tabs. AEM's engineers spent extensive time developing the controller's flow control strategy for a more linear flow output delivery. This means that the flow delivery better matches an engine's need for water/methanol injection, which further optimizes charge air cooling and EGT reduction on turbo Diesels. AEM's Water/Methanol Injection wiring harness for the Boost Dependent HD turbo Diesel controller is terminated with a positive-lock connector on one end and has color-coded wires to ease installation. Both the power and ground wires for the pump are included in the harness which simplifies the wiring process and eliminates any chance of the pump accidentally activating from a short in the system. An additional wire is included for adding an optional on/off solenoid to stop fluid flow when the system is inactive.
