As you can see my car is running very rich and I am losing alot of horsepower, especially on nitrous.
(I have no fuel jet in the bypass tree, I'm at 80psi, and bottle pressure is around 950 on a 100 shot)

I have purchased(it has not shipped yet)a Fields air fuel controller just for the fact that I can save both the NA and Nitrous air fuel maps. I have also heard that sometimes the Apex S-AFC will work to a certain point and then the ECU takes over and erases whatever you changed. Does the Fields have this same problem or any other? (I can still cancel my order if its not gonna work)

 

The fields has been consistent for me over several different dyno tuning sessions.

 

Thanks alot man, thats what I needed to hear. BTW have any of you seen a Maxima run this rich?

 

i just dynoed mine, and yes it runs rich...mine was close to 12:1 stock...whats the best ratio for the most power? 14.7:1 is optimum for emmissions, but what is the optimum ratio for the most hp?

 

I've been told to tune mine to 14/1 NA and 13/1 on nitrous.
