Well quite straightforward:-

1.      Thermocouple sensors (usual range 100C to 600C approx)
2.      Pressure sensor ah la motorola
3.      Hot wire mass air flow sensor - ah la Bosch
4.      Industrial spec'd PIC in peltier cooler if you really want short
        wire links to the thermocouple ;-)
4.      Accelerometer to measure the 'Gee whiz' forces when you get
        the mixture wrong and it blows up in yer face!

rgds ;-)
