I think this product offering sounds like a good idea so far, and that I am considering the system... I'm just an enthusiast and have no proper training in the field so pardon the enquirey if it sounds naive.

The RLS intercooler changes the IAT location so that the ECU receives the "coolest" possible readings which occur after the heat exchange core. That makes sense. I've never seen IAT's placed on hot side of IC, let alone on an IC itself, usually it's right infront of the throttle body, but my experience is limited to honda's and nissans only. However ... I would have thought Lotus had factored this detail into the design, unlike mass market cars where sensors and such details are determined based on parts costs, automated manufacturing, etc... in mind.

Thus can't think of a reason why they did it the way they did unless it was on purpose. Only reason I can think of is that this is some sort of "buffer" and the retarding from ECU was desinged in to prolong engine life (until atleast the warrantee is up). After all for better or worse, lotus is more commercial now than before. Just my laymans guess...

It would be interesting to understand where they put the IAT's in race version cars, such as gt3, or even the limited production 240R, or cup cars (still new to lotus, not sure which cup cars are SC).

Likewise, where is the IAT location for the air to water systems?
