ECU vs PCM

what is the difference between the ECU and PCM?

is the PCM an ECU that also controls auto tranny??

the reason i am asking this is that i came across some ECU pics and
some of them got 2 sockets and others got 3 yet they manage the same
1.6 16 valves daewoo engine. i suppose the 3 socket ECU is actually
a PCM but i am not sure.

what do you think guys?? anybody got his or her ECU out and can tell
me how many sockets it got and what type of tranny you have?

I have 3 sockets and a manual tranny (my ecu is not out though)

Hmmm... this is supporting my theory, the 2 socket ECU is for the 1.5 8 valve SOHC while the 3 socket ECU is for the 1.6 16 valves DOHC.

any body got a 1.5 SOHC that can confirm my theory here??

depends on what you have I think all GMDaewoo vehicles in 2002 or 2003 went to the delphi ecu which has two connections, and it is located under the hood

i have a '99 1.5 Lanos and my ECU has 2 sockets and located under the passenger seat... Right hand drive 1.5 Lanoses got the ECU somewhere near the gas pedal or so... does it have 2 sockets as my ECU??
