wiht mods like that the computer should be able to compensate for the very minimal amount of air flow that is increased

 

thats what i figured too:

Question,

one of the bolts holding my 'test pipe' to my header is MIA, but the flange isn't really loose at all, if there is a small leak there could this be causing a problem?

 

The turbo toronado had an exhaust leak before the o2 sensor that fucked my A/F ratio. Let us know what happens when you get the new pump put in.

 

uhh yea, think about it, your motor sucks in air, then simply stated, burns the oxygen out of it. so what is comming out your exhaust is oxygen deprived. a leak of air before the wideband will allow oxygen rich (compared to the exhaust gases) gases in the stream. I would imagine that since faster moving air creates a lower pressure, that why it 'breaks up' at high rpm is that at high rpm you are creating a faster flow thru your exhaust. thus a small leak would be more apt to let more air in.

 

not that i think the intake is your problem, but at wot how would a MAP car be able to compensate for more air? It still sees the same pressure (zero) so how would it add fuel. A MAF ecu could, but not a MAP imho.

 

compensates for more air by reading the o2

 

bleh...im too used to not running an o2 i forget that people still have them lol. Oh well, next time ill think before i post in EM.

wait, but at WOT it doesnt run in closed loop so maybe im half right?

 

I guess all i had meant to say was that "I know a honda ECU can compensate for a basic intake without leaning out up top"

I will throw on new hardware on flange behind the O2 *since only one bolt is on there now* after I get my grand prix started.

 

if i read this right you are still using the stock cx ecu? if so thats your problem. chip it and tune it

 

By "up top" I ASSume you mean WOT. In that case, no, a Honda ECU cannot compensate for a basic intake without leaning out.

Honda runs ther NA cars in the low to flat 12's from the factory, and since an intake doesn't do ---- for power you swing at most 0.03 AFR leaner. That's why you don't notice anything. :P
