ok guys i just got a 2.8 and 60s installed on my car the yesterday along with an innovate wideband it was installed and tuned by kenny at cobalt addiction and they gave me a great deal for every thing and the car runs awsome. i asked for a very modest tune bc i dont have any cooling mods yet and i cant afford to blow something up right now haha
he drove the car for a while and said every thing was perfect but i specifically saying that the afr should be between 14 and 16 but at WOT its going down to 10.8 or so and im just wondering if thats right, when he got done installing it he said he hadnt installed that guage before and that it may not read correctly

basically if it is reading right is 10.5-10.8 and ok afr under wot

 

sounds like its reading fine. just make sure it is calibrated. it is a little rich though. rich and safe

 

i dont fully undestand the whole AFR thing is a higher number lean or rich and what would be the optimal afr for out cars?
also its about 14.2 when im crusing

 

it should be switching all the time while cruising from around 14.2-15.5(anywhere in between there). these cars particularly like 12.0:1 AFR, to be safe 11.6 is usually where everyone puts them.

 

14.7at idle and cruising.

10.8 seems a little rich, but not horrible. Might get a clogged cat in the future.

I think 11-11.5 would be better for you.

 

ok i always thought that a higher number like 12 -13 was rich and 10-11 was lean at least now i understand it better thanks alot guys

 

yeah think about it logically

It's Air to Fuel Ratio

10.8 parts air and 1 part fuel

If it's 15.0 parts air then it's leaner cause there is more air.

 

yea i understand it now thanks guys i was thinking about it backwards the whole time
