Editing GM Ecotec engine (section)

====L61====
In 2007, the '''L61''' received a multitude of changes, that originated from the ''LE5''. It switched to the higher-strength Gen II block and received a revised cylinder head (enlarged exhaust ports) and camshaft design (increased exhaust valve duration). The engine also switched from [[wasted spark]] ignition to individual [[Direct ignition|coil-on-plug]] ignition; this forced the cam cover to be redesigned. It was also switched to an E37 engine controller with new crank and cam sensors (replacing timing sensor previously found in ignition cassette). These changes increase horsepower slightly and allow the engine to meet [[PZEV]] standards.<ref>{{cite web|title=2008 Ecotec 2.2L I4 ( L61 )|url=http://g5.wrath.org/08_L61.doc|access-date=30 July 2014}}</ref> Compression ratio is 10.0:1.
