MAP/MAF Enhancer to treat the vehicle. MAP Sensor is
short for manifold absolute pressure sensor. MAF Sensor is short for
mass air flow sensor.
Map Sensor Enhancers
Buying A Map Sensor Enhancer
Map Sensor Enhancers are used to manipulate the signal coming from the map sensor and going to the computer. They are pretty simple devices and use resistors and potentiometers to increase the resistance in the circuit, thus lowering the voltage. This lower voltage tells the computer to lean out the fuel.
There are a few different designs of map sensor enhancers but the only real difference is some use two potentiometers instead of just one. The ones that have two potentiometers are called dual edge map sensor enhancers. The only advantage of these is that you can set both pots to different settings and then toggle back and forth between them.
The easiest way to find out if you have a MAP or MAP
Sensor is to go to autozone.com, input the information about your
vehicle, then search parts for MAP or MAF. If the search shows no
results this is usually because your vehicle does not have the part.
