So, I've received a response from competition clutches -

The 2012 and up cars uses a very sensitive crank speed detection system. If the ecu does not see the crank speed up and slow down properly (within what it knows is proper) in between each stage of the 4 stroke cycle (suck, squeeze, bang, blow) it will throw a check engine light and cause the vehicle to go into limp mode.
We have found out that our clutch assembly for the previous gen si's (8037 base kits), when combined with a properly weighted OEM flywheel (22100-RBC-003), will fall within the realm of what the ecu deems as proper and allow the car to run with an aftermarket clutch assembly.
With an aftermarket ecu or perhaps a reflash of the factory ecu you can get around all that and just bolt up a previous gen clutch and flywheel (8037 & 2-800). I hope this clears things up for you.
Thank you,
