What is Porsche pcm?

PCM: Porsche Communication Management System. PCM will receive sensor signals, control the adjustment of fuel supply, gas distribution (electronic throttle), fuel injection and ignition timing and intake pressure, and determine the compensation control coefficient of the engine according to temperature, load, knock and combustion conditions.

Now, all digital transmission systems adopt pulse code modulation system. At first, PCM was not used to transmit computer data, but there was a trunk between switches, not just to transmit telephone signals. There are two standards for PCM, E 1 and T 1.

PCM can provide users with a variety of services, not only digital data private line services with a speed of 2M to 155M, but also other services such as voice, image transmission and distance education. It is especially suitable for users who have high requirements on data transmission rate and bandwidth. Million car purchase subsidy
