MAP Clamp 0-5 Volts Adjustable

Product Information

A MAP clamp connects to your cars MAP sensor and limits its maximum output voltage. The cars PCM (computer) reads the boost levels through your MAP sensor, and outputs this reading in a 0-5 volt signal to the PCM.  By limiting the maximum voltage output you are fooling your PCM to think that it is running less boost levels than it really is. When the PCM sees higher than stock boost levels, it will pull timing, thinking that there is a problem since the boost is so high, when in reality you set the boost that high yourself.  Another advantage to fooling the PCM is that you can pull fuel and lean out your car since engines are set to run rich from the factory.  Installation is very simple and should only take around 30 minutes. It involves running the wires and soldering only 3 wires on the map sensor wire harness which is also 3 wires.  You do not cut any wires.  What you will need to do is strip a spot on each of the 3 wires going to the MAP sensor and solder the wires from the map clamp to them as it shows in the directions that are sent with them. A map clamp must be tuned with a wideband, dyno or anything that allows you to read an accurate AFR (air/fuel ratio). The MAP clamp is fully adjustable, but does comes preset to the maximum of 5 volts, which will not alter the MAP sensor readings when first installed.  This way, you can install it, and drive around normally without having to worry if it is tuned correctly.  This gives you time to install it, and then tune for it later.
