A/F question

[speed_3]

my mods are in my sig. I put my corksport dp on this weekend, I have a CEl for the o2 sensor b/c of the dp, didn't get to drive it around too much b/c of the rain up here in NY but i got on it today and my a/f on my ap is reading like 9.8 at WOT, thats not good. Just looking for a little input on my situation.

9.8 is OK I'd think...the lower you are, the more rich you're running. It may take a couple of days for the ECU to relearn the fuel stuff. Disconnect the negative terminal from the battery for a few minutes to reset the ECU, then just give it a few days to sort things out. Until then, you're fine...you may burn through more fuel than you're used to, but you're not running lean.

10.0 is about par for the course. Even with AP.

thanks for the fast responses guys i was just a little worried b/c i saw some talk about like 12.5 being the target.

 

[SwampAss]

14.7 is stoichiometric or considered perfect for complete combustion.

11s are safe. 12.5 is close I think.

Anything low is fine. Once it starts creeping up past 14 at WOT I'd be concerned. You want it a little rich to help keep things cool

let the car learn it first and c what u get, when i did my dp i smoked in idle but since then iv uped the fuel and hav had no problems, run 14.5-.6 idle and 12.0 at open throttle

Where did you get your Xede with PnP...? Is it full PnP?

Sorry for the (jacked)...
