The ratio of branching fractions and the difference in $CP$ asymmetries of the decays $B^+$ → $J/ψπ^+$ and $B^+$ → $J/ψK^+$ are measured using a data sample of $pp$ collisions collected by the LHCb experiment, corresponding to an integrated luminosity of 3 fb-1 at centre-of-mass energies of 7 and 8 TeV. The results are where the first uncertainties are statistical and the second are systematic. Combining this result with a recent LHCb measurement of $$A^{CP}$$ ($B^+$ → $J/ ψK^+$) provides the most precise estimate to date of $CP$ violation in the decay $B^+$ → $J/ψπ^+$,
