I have the SAFC II and am ready to install it and begin tuning. I have read so many different posts on what a/f ratio I should be tuning to. My car has all the bolt-ons available for the Maxima. Intake, cat-back, headers and udp. I was not able to get a good response on Maxima.org. I need to know what to correct the a/f ratio to. Thanks.

 

A few more questions:

1. What do I set the number of cylinders to (I know I have a 6 cylinder)? ex: the 350Z uses #1 setting.
2. During the "self learn the throttle opening sequence," do I take off my intake and manually hold the throttle valve open? Or is using the pedal with my foot fine even though it's drive by wire?

 

From what my tuner has told me...12.8 to 13.2 to 1 at WOT is good for N/A cars .He has been at it for 25 years

 

the best af will be the one where your car makes the most power on the dyno without detonating. this could be mid 12s or high 13s there is no cookie cutter af that is ideal for all. and you will not have just one af your car may be leaner down low than it is up top and still make the best power youd be best off letting a pro do this for you

 

I think I found the answer ~ 13.5 across the board. Thanks.

 

Thats where I made the most power!
