For the most part the engines are identical.
Aside from slight piston/ring changes, the 2010+ were fitted with larger diameter crankshaft ends and flywheels in the aim to stabilize throttle response by increasing crankshaft inertia (by 7%; Yes, it does work!).
Maps were reworked for the 2010+ and then again adjusted for the 2012.
OP: Shift star installation guide from an 08 will work just fine!
