i am buying a air/fuel ratio gauge, it is not digital so it has the numbers on it. i did some searching and found on the newbi thread that one person was running like 13.3 or something?! i was wondering if anyone knows what number it should be running at, so what would be lean/what would be rich/ and whats just right?!

 

Not sure about the numbers, but make sure you get a wideband o2 to go with that... or you're going to end up with a christmas light party on your dash.

 

yeah i know i need a wideband for a more eccurate reading but i dont have 300 dollars to spend on one!

 

and if I remember right...

below 14.7 is richer
14.7 is perfect
above 14.7 is leaner

 

14.7 is idle and stoich.. while cruising. lol if you tune for 14.7 when WOT you go boom. I think 12.3 is ideal but i'm not sure. look up threads by Alchemist.

 

so tune when idle? i always thought when at wot.

 

you tune at wot. you cant tune at idle much and if you do its pointless

 

Well... at WOT and different rpm range right?

 

yeah exactly.

 

n/a tune for about 12.6-8... i think FI tunes for about 12 flat... not forsure about FI... but im n/a and that is what mine is set too

 

i tuned for about 12.5.. you can adjust anything over 30% throttle.. there really is no point too touch anything else b/c the ecu keeps the mixture right at 14.7 anyway. At WOT i was dipping down into the 10:1 range before I installed the emanage.

 

It really hard to blow up NA cars, because the margin for error is bigger when comparing to turbo. You have to outright neglect it for a long time.
