from what I read on the HP Tuners site, the 1.8 N/A US Spec Sonics use the same hardware (known as the E83 PCM) as the 2009-2011 Aveos, so you could either Get a Sonic PCM (it would plug right in since there are no physical differences between a Sonic PCM or an Aveo PCM) or flash your Aveo PCM with a Calibration from a Sonic.
