Engine control unit merge
What is the difference between Power-train control module and this article? Why do they both exist? --Mjrmtg (talk) 17:47, 14 June 2010 (UTC)

There is no difference between PCM and engien control unit, so I think pages should be merged. 81.201.62.154 (talk) 15:21, 25 March 2014 (UTC)

A PCM or PCU controls the engine AND the transmission. It is different from an ECU (which is just for the engine) or a TCU (which is just for the transmission). — Preceding unsigned comment added by 81.159.129.54 (talk) 10:31, 19 May 2014 (UTC)
