Very nice man. :thumb: So only the HHR version (LE8) is flex fuel? OR will the LAP be also?
BTW...I nominate first sticky of this section. |
Also, with tuning could the LAP or L61 be used with E85?

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... |

Any at all or just new code for minor improvements? 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.... |
damn. and I thought GM changed the name because it used a new head gasket. ;)
