STL Universal Fuel Cut Defender

These are active voltage clamp fuel cut defenders, used for adjusting the MAP (manifold absolute pressure) or MAF/MAS (mass air flow) sensor's output so you can feasibly raise boost pressure on a turbocharged vehicle, without alarming the ECU and causing fuel cut.

They work to keep the ECU from "seeing" boost and cutting fuel.

These are not passive resistor/potentiometer/transistor voltage regulators. While both devices achieve a similar result, the passive devices do so by essentially creating a crude linear voltage regulator. The disadvantage to these types of FCDs is that they usually create at least a 0.6V voltage drop throughout the entire MAP sensor output range. While it doesn't seem significant, the lowered voltage actually inhibits your stock ECU from making accurate A/F ratio measurements and adjustments.

These FCDs use a more complex circuit to provide the following features:

Universal These units will work with virtually any car that has a MAP/MAS sensor running on a +5V reference voltage (most fuel injected cars).
Quick and Accurate Voltage Clamping Rather than adding resistance to the entire MAP/MAF output range, these FCDs will only clamp down the output voltage down at a user specified maximum level.
Minimal Noise Absorption The circuits have a built in filter, which removes unwanted noise. They also feature protection from the voltage spikes that are characteristic of a car's electrical system.
Sturdy Construction These FCDs are built on printed circuit boards layed out specifically for this application. The protective cases allow you to easily mount the unit in virtually any of the cooler areas of your engine bay. The units are handmade domestically and tested by a real person (not a machine overseas somewhere!) with quality components. They are also water/chemical resistant.
