Air/Fuel Meter- Best Performance!
I am planning on getting an Air fuel meter, ideally, what should the meter read under WOT?
Also- is there any way to modify the mixture, besides buying a apex s-AFC?
Thanks

Ideally you'd want to be at stoich (14.7:1 A/F ratio). Acheiving that will be hard. An aftermarket fuel pressure regulator, different/ more injectors, boost management, custom programming are ways to control it. Basically, as long as it's running fairly strong and kinda rich you should be happy. Lean motors don't last real long.

If you get a cheap AF gauge just use it to tell you if you are dangerously leaning out or rich. It is not percise(spelling) enough to tune your car. If you are getting an expensive *** one then you can tune yourself. I would rather buy a cheap one, and have a shop tune it perfect.

Why would you use a A/F meter AND a s-afc? Doesn't the AFC have a meter built in? Or am I wrong. (I don't really know that much about them).
I suppose if you just get a chip you wouldn't need any of that stuff to tune your car because it would the ECU would be reprogrammed with the best performing settings, saving a lot of work....

I have the EFI systems air fuel guage. It has air/fuel ratios as well as injector load. I am extremely happy with it. The air/fuel lets you know how rich you are running and the injector load tells you how hard your injectors are working (so you know if you need bigger injectors or bigger pump).
You should run 12:1 (rich) under boost. That gives you best power and safety margin so you dont blow up your engine. You should NEVER go lean under boost.

sorry, i misread. I thought you had a turbo car. Never the less, you should be running rich under full throttle for maximum power (not too rich of course). Sorry about mistake on turbo/non turbo.

The EFI meter doesn't have any way of modifying the mixture does it? How does it wire in to detect the injector pulsewidth?
