PGM-FI works by injecting the right amount of fuel per cylinder based on specific engine data. The engine's control computer has sensors which measure the temperatures of the engine, coolant, oil, and outside air as well as pressure sensors to monitor oil and barometric pressure. Based on these readings and the location of the throttle, the Engine Control Unit (ECU) calculates how much oxygen and fuel should be mixed for optimal and efficient performance.
Cars with PGM-FI do not have to sit and warm the engine up in the winter season because the ECU calculates at what RPM and the fuel and air mixture the car requires to be at a normal engine temperature range
Hmm learn something new today. Though this info have been @ the internet for dun know how many donkey years. Any bros care to support on this info?

wat it mean is at any given temp or condition the ecu can program the best/optimal fuel/air mix for the engine
still need warm up rite in the winter, as the engine oil is still not in optimal temp to do a good job to protect the engine.
....pls correct if wrong
