We have worked on a variety of Honda models. This turbocharged Civic is an example of a car tuned with the PSC1-001 and large injectors. The PSC1 is used as a programmable MAP sensor. It adjusts for the large injectors at light load, fine tunes the fuel under boost and limits the maximum output of the MAP sensor to avoid fuel cut. A nice side benefit of the PSC1-001 is that it provides a real-time readout of manifold pressure that is accurate to 0.2 PSI
