Does PTuning have their own swap kit?

No, they'd install the RSM kit. I talked to RSM and they don't have any FA24s right now and recommended I source one myself.

I was thinking about going back to PTuning for a custom tune on my swap once my little bug is worked out. This time, I' make sure Taun doesn't turn on FFS (like he did last time LOL).

LOL! Yeah, once I decide to move forward with the swap, I'll schedule with them for the whole thing. I'll just have the engine and kit shipped directly to PTuning and let them tune it as well.

Would i be able to swap my 2015 ecu for a 2017 Ecu to avoid changing the cam trigger and reluctor wheels and sensors since I’m gonna do a tune anyways? Would this have to be a new ecu or can I get a used one and redo the security pairing?

I'm pretty sure there are too many differences between the early and later electronics for such a proposed swap.

Revolution did it.

That's a great resource, they're saying the surge tank for coolant limited the knock response? and a bigger coolant surge tank from the FA24 helped with better cooling.. is it for better pressure regulation

I think the translation is throwing you off - what's coming through as "surge tank" is actually referring to the intake manifold. Part of the design of an intake manifold is to serve as an "intake air surge tank" to try and even out the distribution of intake air to each runner. The section that does this is also sometimes referred to as a plenum, and the Wikipedia page for "plenum chamber" actually has a really good definition of what this does:

"A plenum chamber is a pressurised housing containing a fluid (typically air) at positive pressure. One of its functions is to equalise pressure for more even distribution, compensating for irregular supply or demand."

The article indicates that the car made more power with the FA24's manifold and throttle body on vs. the FA20 red manifold and throttle body.
