You get the MAP signal from the engine side of the throttle plates. You could use the taps on top of the TBs or the signal to the FPR or whatever. I had to use a pulse damper since I needed a less jumpy signal. You can get air temp using a stock Bosch sensor cut from an old AFM or from a car with a separate sensor if you find one with similar output. They are just negative temp coef. resistors. Mods like this, which are standard on new cars, really wake up the S14, especially in below 4000 RPM street driving. Broadens the powerband very noticeably. Transforms the car.
