yeah...i really don't know why Subaru would have used an EGT sensor. they aren't terribly quick reacting. they really just give you a rough ballpark type idea.

 

I'd think an o2 sensor...even the single wire would be better, because it can detect lean conditions right away. To detect a lean condition with an EGT you need to wait a couple seconds for the temp to climb a couple hundred degrees.

 

I don't think the ECU;s would be drastically different....as i said....prolly just slight timing changes for the better fuel they have.

 

 

 

Myxalplyx: GET SOME EXHAUST on that thing!!!! i'm curious what an otherwise stock EA82 with exhaust will do....i know it's a huge difference in the seat of the pants...just curious to see a difference.

The gas that we are using is 95 octane minimum. You can also get 98octane and even 99 from some countries. ECU might be different from yours because it is programmed for different fuel and to work without lambda sensor

Regarding octane, are we talking the same rating system? The USA adopted a screwy system in the 70's.

OMG thank you northwet, do you have a link for that info.

 

 

(I'm on a couple "drift" fourms and this is my biggest arguement with the "drifters" )

Not right off hand... just lived through it. Octane used to be stated as either "Motor" or "Research" Octane. Then around the first energy circus... er, crisis in the early 70's they made a "new" number which was (M+R)/2... an average of the two numbers. Usually ended up with gas of poorer quality being labeled with a higher octane number.
