Hi, i just did a jdm ls swap, and it seems to be running great, i swapped it into a 93 civic ex 2 door, and somone who has done the same swap, told me i needed to get a second map sensor from the junk yard and splice another sensor cable for a map sensor, from a chassis wire harness, to the map sensor on topp of the throttle body, ive never thought the car would require 2 map sensors, i dont know what this is all about and i would like to see if anyone out there knew if he is right, or if he did that for no reason, somone out there please let me know if you need more details on the situation of if you know whats going on thanks.
