jms_1JMS Chip & Performance has the key to your 2011-2014 Ford Mustang 5.0L and it is plug and play. Controlling your spark and ignition voltage to eliminate spark blowout has just gotten easier. All the details are below.

Official Release:

JMS Chip & Performance recently upgraded their line of popular PowerMAX Plug & Play products, releasing the industry’s first and only complete ignition solution for 5.0L-powered Ford Mustangs. The new PowerMAX SparkMAX V2 Ignition System Voltage Booster for 2011-2014 Mustang features exclusive JMS digital technology designed to provide up to an 85% increase in ignition voltage.

The JMS PowerMAX SparkMAX V2 provides the highest continuous voltage and amperage output without noise, and offers up to 31 volts of energy for coil-on-plug 2011-2014 Mustang ignition systems. This easy to install plug & play device combines the highest maximum continuous amperage and voltage available in an ignition-boosting product. The extended benefits of increased spark and voltage include; completely eliminating spark blowout in supercharged or turbocharged applications, and improving power and fuel-economy by allowing a wider spark plug gap to be used for optimized performance.

PowerMAX SparkMAX V2 has two user selectable maximum output voltage ranges, ranging from 25 or 31 volts. Output voltage is controlled by a simple adjustment on the device or via the optional remote-mounted control knob. You can also control the voltage ramp-in and ramp-out rate to maximize performance and spark delivery without sudden spikes in energy. The device has a continuous output rating of 31 amps, and will operate with an input voltage between 9.5 and 19 volts DC.

The recently released features a proprietary enclosure and industrial heat sink, 10 gauge heavy-duty wiring, 40-amp fuse, plug & play design using OEM-grade connectors, and a host of innovative features to further improve the user experience. JMS is the only company to offer user-adjustable voltage ramp in and ramp out rates, which allows for maximum control over the ramp-rates. Depending upon device type or model, voltage can be controlled via time, boost pressure or a monitored voltage, and it’s easy to setup via simple to use knobs and switches.

JMS FuelMAX V2 Fuel Pump Voltage Booster Kits are shipped complete with everything you need for installation. Included in the kits; PowerMAX SparkMAX V2 device, heavy-duty OEM-grade wiring harness with OEM-grade connectors, user adjustable Hobbs pressure switch, 1/8″ NPT adaptor fitting, wiring terminals, wire splices and heat shrink, solder, vacuum line and tees, mounting hardware, and 40 amp fuse. Internal boost kits include; vacuum line, and the plug and play pedal position sensor kits include a pre-engineered harness with OEM-type connectors.
