So only the HHR version (LE8) is flex fuel? OR will the LAP be also?

What exactly are the major differences betweent the L61 and LAP?
Any at all or just new code for minor improvements?
Nevemind. I found the thread that infos in...

GM tends not to hand out new RPOs for minor upgrades.
Every 2.2L gasoline ECOTEC without VVT from 2000-2009 is called an L61, there have been numerosu small changes and an entirely new block, head, ignition system, multiple fuel system, etc, etc....
