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

Yes, like any engine it could be tuned to run on E85, but it fuel system is not optimised to do so as in the LE8

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....
