Default Impala SS EFI Live question

I was wondering what I chose for engine controller in EFI Live in order to scan a 08 Impala SS?

My Dad's car is popping a code, someone at the parts store told him it was a code for the gas cap or something fuel related. New gas cap and a few days later the code is back. So I'm up on vacation and figured I'd read the codes out.

Once I have the codes I'll post them up, see what the LS4 crowd thinks it is.
Thanks!

I'm not familiar with the EFI Live interface, but the '07 and up LS4s have the E67 ECM if that helps.

Sure does, thanks! I'll pick that tomorrow when I go out there instead of guessing until it worked.

I had that problem a couple of years back and had to replace the EVAP canister.

So the code is P0455. Do these cars have common EVAP canister problems? What other areas can I look at?

Where is the EVAP canister located on these cars? My Dad tells me a tree branch had fallen in his path, maybe it knocked a vacuum line loose if he ran it over?

EVAP vent solenoid is by the tank. I think you can reach it without too much hassle.
