running a high compression application 11-6-1 wideband settings that i have found say 14.7 seems a little lean to me.... should i try richening it up just a little?

 

Do you trust your wide band or no?

It says it's 14.7 that's stoch for a gas motor. That means, not rich, not lean. I fail to see what you are really asking.

 

14.7 is perfect when you are at idle or cruizing. What is the a/f reading when at w.o.t???

 

not stock motor, high compression... reason im asking im using the d16y8 intake manifold, so it idles kind of erractic, also it is throwing code 1 which is o2 sensor, i am not using stock o2 bypassed it and wired wideband o2 to my stock wire harness.....

 

What does a Y8 IM have to do with your idle other than its probably the source of a vacuum leak somewheres?

 

wow, you have an ecu that supports wideband input?

 

guy at local tune shop said to just bypass stock o2 an wire in wideband o2 in its place

 

Sounds like he didn’t explain himself well. Some widebands have a narrow band out put and you could use that. Some rom editors allow you to disable the o2 sensor and some well one let you run closed loop with a wideband. If you have a stock ecu and unplug the o2 bad thing will happen.

He meant to get a chipped ECU that is capable of being tuned with a wideband 02 sensor. Your ECU is probably wondering what the **** is going on.

Get it chipped before it becomes unhappy with it's home life and starts seeing other people.

 

lowest value is 7.40 highest is ---..... but while idling it will flash e 2 and then sometimes heating up o2 screen.... not sure what to do now.... idles at 14.5 to 15.6 o2 code is gone though so that is a plus...lol

 

what?

x2.

 

got o2 hooked up as follows off the LC-1..... red to power, green, blue an white to ground, yellow to ecu harness (o2) under the hood, brown to green wire from xd-16 gauge, black wire taped off.... while car is idling the gauge flashes e 2, then somtimes will go through o2 heating up cycle..... just not sure how to fix this

 

Black wire is a ground wire. It needs to be treated as such, not just taped off.

 

well if i read the online manual it said black is calibration wire? car runs fine till i let off gas while driving numbers jus go crazy then i get the o2 display, push back on gas an its back to normal.....

 

my neighbor suggested running my stock o2 sensor, an putting wideband o2 down further on my headers
