  Allowed $\beta^+$ branches of very proton-rich $fp$ shell $Tz=-2$ nuclei at
the proton drip-line are calculated in the full fp valence space. The $\beta^+$
decay half-lives calculated with the standard quenching factor
($g^{eff}_{A}/g_{A}$)=0.74 are in good agreement with existing experimental
data. Detailed branching Gamow-Teller strength are predicted but comparison
with experiment is still difficult since, in most cases, spectroscopic
information is not yet available.
