Single External Wideband Sensor Power Kit:
The Infinity 506 includes one internal wideband sensor. Supercharged, twin turbochargers, and naturally aspirated applications require a second, external wideband sensor, like the AEM External Inline Wideband Controller & Sensor.
This kit provides a powered circuit for the external wideband sensor and includes detailed instructions.
Wideband, Fuel Pump, and Accessory Power Kit:
For applications that require an external wideband sensor, high capacity fuel pump, and other accessories like a FlexFuel sensor or turbocharger boost control solenoid, the ScienceofSpeed Fuel Pump, Wideband, and Accessory Power Kit replaces the Single External Wideband Sensor Power Kit.
New high-capacity in-tank turbine fuel pumps being used today (such as the Walbro 450 LPH) have increased electrical current demands. The factory fuel pump power system is not designed to support the current draw of these pumps and can lead to power pump performance.
The ScienceofSpeed Wideband, Fuel Pump, and Accessory Power Kit adds a 40A circuit to power up to a 25A fuel pump.
Read this technical overview for results from testing of this product.
In addition to powering the fuel pump, the power distribution kit has an available an additional three switched +12V power sources for accessories such as wideband sensor, boost control solenoid valve, and FlexFuel sensor for example, and includes detailed instructions.
