ive always wondered that evan. maybe because where its built? or because on the race cars they dont mind the extra noise.. and dont want the extra weight?

You guys are kind of on the right track. The CR is an execption to the REAL answer im looking for. In that case it was about the weight savings believe it or not.
Here, I'll limit it down to the accords. Why on the V6 but NOT the 4 cylinder? I mean, think about it there's some NICE 4 cylinder models with Navi etc, so it's not that fact that Honda puts nicer s**t on nicer models.

Could be one of two reasons. The higher models usually have the bigger, higher performance engines, so they produce alot of heat, and the insulators soak up the heat. They also soak up any extra unwanted noise, so its quite while driving.From my knowledge, that's correct so I'm going to go ahead and post another question since I have a bit of time now.
A hood insulator is a fire-resistant type of fabric that clips onto the underside of the hood. It's main functions are noise reduction, keeping heat off of your nicely painted hood and possibly assisting with keeping a fire from spreading during an engine bay fire (there are details on that). Anyhow...
Why do some Honda models get it while other don't? In other words, why do you see it on the Accord V6 NOT the 4 cylinder, the 89-91 CRX but NOT the civic, the regular s2000 but NOT the CR?
If you can answer specifically to the models, then even better. But I want to hear the general reason why - there is a specific reason.
also the PCV valve helps prolong the life of your oil!
i was going to edit my answer and put this in there.. but... it didnt think it was that important for an answeralso the PCV valve helps prolong the life of your oil!

actually one more guess thats probably a better one. its there to keep the metal on the engine from touching the metal of the hood and thus causing a short, which would then lead to the fire i talked about in my previous post.
I'm gonna guess it's for noise suppression or to keep the paint from peeling.
That's basically correct! It's because the engine on some models sits closer to the hood. It's not dependent on EXL or V6 etc. It doesn't matter the "class", it's with how the engine is situated on some models. However, the CR is the exception (it doesn't have it for weight reduction) although the engine placement is the same.Thus on the applicable models, the insulator helps to protect from all of the above: heat on the painted hood, fire & noise reduction.actually one more guess thats probably a better one. its there to keep the metal on the engine from touching the metal of the hood and thus causing a short, which would then lead to the fire i talked about in my previous post.
K, time for my question:
The ECU uses closed-loop control, a control scheme that monitors outputs of a system to control the inputs to a system, managing the emissions and fuel economy of the engine. what are the two MAIN things the ecu determins/controls to ensure the lowest emissions and best mileage?

No, just play it out. You are doing fine.Nope, perhaps my answer is not a good one, RonJ should i PM you and verify my answer?
