So I have a hand full of map sensors, in a quest of finding way was wrong with my civic I had a grabbed all map sensors I could find. Biggest thing I've found is that almost all non vtec civics have a 079800-3000 map sensor, and also my 99 Crv, and my 96 3 stage d15b came with the 3000 sensor. Now from all d16y8 's that I've seen have 079800-3280 map sensor, when I run the 3280 on my y8 it is zippy and fast, and all 3000 sensors seem to feel heavier on the throttle, strong torque yet not add zippy and vtec transition is barely noticeable, as well ac does not disable when I floor it with the 3000, but with the 3280 ac will cut out when your driving becomes more aggressive. Any one able to do side by side testing of the various sensors and a graph read out. I would imaging the best way to accomplish this would be to have all sensors fed from same battery and ground and all connected to same vacuum source, and some type of data logger representing a linear line graph.
