In the vast majority of cases you can use either the Manifold Air Pressure or Throttle Position Sensor setup. The easiest installation is with the MAP sensor version as the sensor is built into the ECU and simply needs a vacuum take-off from the manifold connecting up. The MAP system also can run forced-induction if that is something you need.
The TPS setup requires you to fit and wire up a throttle sensor if you do not already have one fitted so is slightly more work than the MAP system. If you are running extreme race-spec camshaft profiles then the resultant pulses in the inlet can confuse the MAP sensor readings unless you are careful so in that case you would typically go the throttle sensor route.
