Ideal Naturally Aspirated A:F ratio for a B18B1
You think there's one blanket AFR for every load and RPM? Do you realize that the stock calibration is a table approx 12x12 and that each cell may be targeting a specific afr?
Stock B18B1 calibration probably runs 12:1 at max load and rpm, infinity:1 off throttle above 1000 RPM, just rich of stoich at idle, and 15:1 at light cruise above 45mph. You'll actually make more power by leaning out the max load and rpm region.

No, I know there is a vast table. (this is why I said "anyone know the stock numbers, numbers as in plural, as in more than one)
My car is doing 13.8 at WOT, 14.5-15.0 at light cruise, thats why I was curious if someone knew a few EXACT numbers for where it should be, or had that table.

that's pretty lean WOT, should be in the 13.2-12.8 range. I've seen cars that liked 13.5 though.
the exact table can be determined on the dyno. Every engine is different in what it likes.

I thought it was a spec on the lean side.
Car has a stock PR4, and its just an intake/exhaust car (stock header). I am getting a VAFC soon so I can richen it up a bit and see how it likes it.
