First - how accurate are the temperature readings? They look a bit warm for wintertime, but plausible if you're in a garage or in the tropics.

Does your ignition timing look correct while cranking?

Any reason you're using 3.2.4 firmware? Consider upgrading to the latest, 3.4.2, while you're just getting started. Less to re-tune later.
