First off, I personally have no interest in upping the HP on my own car, or modding it in any way post-market, I like my car the way it is!
That being said, I'm not sure if this qualifies as ECU remapping, I was more thinking along the lines of electronically controlled variable valve timing, but I didn't know if that could even be approached on the current engine (even if somewhat inefficiently) or would require a total powerplant redesign.
Since Atkinson cycle engines and Otto cycle engines differ in the inlet valve timing, I was wondering if changing that "on-the-fly" could increase torque, for example in Sport mode, but then switch back to the more standard mode.
Anyway, I'm waaaay out of my element, but was just curious. Thanks for the response!
