It's all about reducing the overall output. Reduce the source of it, you have wayyyy less to deal with in every other step and trick you play with. It's why something like a modern vehicle, so VW, Audi etc, there's thousands of tables for the ECU to calculate what it should be doing with the engine. Why would you NOT reduce emissions the most effective way possible, when it has very minimal tradeoff, AND manufacturers are always struggling to meet the current standards. -

Yeah I've personally seen the RB26 pull 30 degrees of ignition timing out of the base timing map if the ECU detects a cold start, it nearly starts misfiring because of it around 2000 rpm and it feels like the engine has no power. I'm just surprised that modern OEM control strategies are actually trading off efficiency for in-cylinder emissions. I would expect something like aggressive EGR dilution + tumble generation valve use to improve EGR tolerance to reduce in-cylinder NOx + HC from crevice volume while also reducing throttling loss vs pulling out some timing if not knock-limited. -

You're more than welcome to - looking forward to meeting you!! The turnout depends on the event and location... Pizza Runs on a clear night can drag out a decent crowd!
