Re: Running Lean, nearly stock, wtf.
wiht mods like that the computer should be able to compensate for the very minimal amount of air flow that is increased

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? |
Re: Running Lean, nearly stock, wtf.
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.

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. |

the intake should have NO effect on how lean/rich I'm running since honda's are MAP cars, the ECU should be taking care of it. |
Re: Running Lean, nearly stock, wtf.
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 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. |
Re: Running Lean, nearly stock, wtf.
if i read this right you are still using the stock cx ecu? if so thats your problem. chip it and tune it

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 |
