Best Air/Fuel Ratio??
I want to hear from anyone who has dyno-tuned their J series, please. I would prefer to know the NA version best possible ratio to shoot for while street tuning with Ktuner. I have a Type S with all the usual bolt-ons.

not too rich, not too lean.
it's not just one value...you'll have different values for different conditions....
-idle
-acceleration
-cruising
- wide open throttle
each condition will have different optimal A/F ratios.
you'll need to data log to get data..once you have data, you can then adjust accordingly...
the richer the air/fuel mixture; the more power to a certain degree.

I'm specifically talking maximum power at WOT
The rest of the fuel map is easy to set up but without a dyno to measure the results of 12.0 to 13.0 AFR I would be guessing.
I'd like to hear from someone who has tuned theirs so I have a good base line of what the average J likes.

Like Justin said, it depends on a lot of different aspects. Noticed you’re in Canada, that could also effect your a/f ratios, compared to someone in Florida or Colorado with the same j series, etc…..
There is a forum member here who does e tuning I believe, I also think he only uses flashpro, I could be wrong.
Dom-gsr I believe is his username, but not 100%.
