Sirs,
I have been logging for a few weeks and cannot seem to nail down a consistent Open Loop SD tune. I have noticed that the same tune reacts differently at different times.

Example.
This morning IAT averaged 55 F (52-66), AFR averaged 14.68 (12.50-16.81).
This evening IAT averaged 100 (91-111), AFR averaged 15.08 (12.64-16.82).
Both runs were ~30-45 minutes under mixed daily driving, no WOT, same tune.

1. How much does temperature effect AFR?
2. Are these differences temp related or something else?
3. If temp related, what map should I change to compensate?

thanks! (also posted on ls1tech...)
