OK I hooked up my wideband to my car and did a test pass in almost 100 degree weather... I had an AFR of 13.8. I adjusted it to be at 12.9 and it read 12.9 when I checked it right after. Now later that night it showed an AFR of 12.3. So obviously the car made an adjustment for the cooler weather.
So my question is, what AFR do you shoot for when setting the AFR. If the car adjusts as needed temperature wise, how do you know where to start. What if you were dynoing your car on a 90 degree day or a 50 degree day... would you set your AFR the same? I see that N/A cars like 12.9 or so AFR... Well what about on a 90 degree day when it wants to be leaner...
Sorry if I keep repeating my self...
How would I go about setting my AFR...to make it ok for all outside temps...?
