Overview

The MMX SRV Controller is a Short Runner Valve Controller designed for 6.4L HEMI car and truck intake manifolds. It simplifies the installation of a 6.4L intake manifold into a 5.7L powered vehicle. The controller features four pre-terminated connections, powers from the vehicle's under-hood fuse box, grounds to the chassis, and uses a coil pack for its RPM signal.
Show original supplier description
The MMX Short Runner Valve (SRV) Controller is an in-house designed, developed, programmed, and assembled module for the 6.4L HEMI intake manifolds. This controller is specifically engineered to simplify the process of installing a 6.4L intake manifold onto a 5.7L HEMI-powered vehicle. The controller draws power from the vehicle's under-hood fuse box, grounds to the chassis, and obtains its RPM signal from a coil pack. It is also compatible with aftermarket ECU solutions, making it suitable for custom builds and performance upgrades. Operation is managed via a dial, allowing the user to select the desired RPM for the SRV to open. MMX recommends 4550 RPM for stock cam applications and 5150 RPM for aftermarket camshafts. For optimal performance and to best utilize the short runner valve's capabilities, mounting the module inside the vehicle is strongly recommended. A status LED on the SRV harness connector indicates operation: solid green when the engine is running, flashing green and red if there's an RPM error or the engine is off, and solid blue when the SRV is actively actuated. The product is subject to local and state emissions compliance laws.
