L8 is simply plug and play with a PF09 aka 4x4 TPS and inverting the wires for it, P8 should be just the same!

So far as I know L8 can do nearly everything the P8 can do, such as Anti lag, launch control, CL, it has 128K memory (Double that of it's predecessors) , in addition WS is native on the P8 and just requires enabling.
