  We report on analysis of 308.3 hrs of high speed photometry targeting the
pulsating DA white dwarf EC14012-1446. The data were acquired with the Whole
Earth Telescope (WET) during the 2008 international observing run XCOV26. The
Fourier transform of the light curve contains 19 independent frequencies and
numerous combination frequencies. The dominant peaks are 1633.907, 1887.404,
and 2504.897 microHz. Our analysis of the combination amplitudes reveals that
the parent frequencies are consistent with modes of spherical degree l=1. The
combination amplitudes also provide m identifications for the largest amplitude
parent frequencies. Our seismology analysis, which includes 2004--2007 archival
data, confirms these identifications, provides constraints on additional
frequencies, and finds an average period spacing of 41 s. Building on this
foundation, we present nonlinear fits to high signal-to-noise light curves from
the SOAR 4.1m, McDonald 2.1m, and KPNO 2m telescopes. The fits indicate a
time-averaged convective response timescale of 99.4 +/- 17 s, a temperature
exponent 85 +/- 6.2 and an inclination angle of 32.9 +/- 3.2 degrees. We
present our current empirical map of the convective response timescale across
the DA instability strip.
