Most sensors are 5v on the car (like the RPi) thats TPS, MAP, IAT, CT etc. the only things that are 12v are injectors coil and possibly lambada. All the RPi has to do is know that if it puts out 5v to a sensor it then reads the voltage comming back and puts it within a range to establish where it needs to be in any particular 3D map.
The main map is something like Revs and TPS to IQ and the same for ignition advance with trim maps then for everything else to add or remove fuel.
