I've Just been looking through Elearn at the pressure and temperature sensor and it has a graph showing the different resistances to indicate the different air temperatures (graph below) and I've read that a lower intake temperature means the engine will inject more fuel so my question is if I splice in a resistor to increase the resistance to my desired temperature will this effectively increase the fuel flow rate?

So those mod chip things basically do the same thing but cost a hell of a lot more than a resistor. If it does work then great :). Making my car run rich is what I'm trying to do ready for turbocharging

You're a little wide of the mark.

Even if those chips/resistors worked: they don't -- the ECU will sense a rich mixture and either throw a hissy fit or lean out the mixture -- you need a complete new map for the ECU (and it needs to be able to distinguish boost as well as vacuum).

At least one very crafty Polish person has managed to do this, but if you're still pondering about resistors, you're about 15 years away from that point.

Often in order to meet the fuelling requirements of a turbocharged engine you'll need an aftermarket ECU mapped to suit, a 2 or 3 bar MAP sensor, an uprated fuel pump, bigger injectors, an aftermarket fuel pressure regulator.

There are lots of decent books out there on turbocharging -- why not read a few!
