What should this guage (Air/Fuel Guage) be reading while driving? And what wire did you guys tap into for power 12V?
Thanks!

 

an a/f gauge on a computer controlled vehicle will jump back and forth due to the computer changing the a/f constantly. the only time the gauge will do you any good is during WOT. during WOT the gauge will most likely read rich. if you want it to do you any good, you will need to buy the modified gauge that only read higher voltage. the modified a/f gauges will only read during wot or close to it but it will give you a much better idea of what your a/f mixture really is. if you want a link to the modified gauge just post, i will try and find it.

 

Thanks for your help!

 

AFM will soon be selling a new EFI Systems Wide-Band monitor for around $560.

 

Here's the AIR/FUEL gage I just ordered.

That looks like a better solution to the question of your A/F readings than my Autometer

 

Thanks guys! I Really appeciate your help!

 

I just order this AF from nordskog along with the boost & fuel pressure since they have recall on them. I'll try those out, see what happens.
