Well, I know that the trap door sensor is a bit different from a "hot wire" style MAF, and that this is used for fuel on the stock ECU. I also know that the pressure sensor looks at boost/ vaccum and these parameters affect the timing on the RX-7... so what's different between a pressure sensor and a MAP sensor? I thought that these were the same thing, no? And if you cant have both, then why does this car have both systems?

I mean, a "pressure sensor" is fundamentaly the same thing as a MAP sensor, they both sense pressure, or am I totally missing something?
