Using a combined configuration interaction and many-body perturbation theory approach, we calculate the level energies of 1s22lq and 1s22lq-13l' (1<=q<=8) complexes in iron and nickel ions. Comparison of 1s22lq energies with experimental results shows that the calculation is accurate to within ~0.15eV for these levels. The accuracy of 1s22lq-13l' energies can be slightly worse, at ~0.5eV. The theoretical wavelengths of 2->3 transitions of iron ions are compared with the published experimental measurements, and discrepancies are found to be mostly within {+/-}10m{AA}. Similar accuracy is expected for wavelengths of nickel ions. Such accuracy is a significant improvement over that obtainable with standard configuration interaction methods. A complete table of 2l->3l' transition wavelengths of all L-shell ions of iron and nickel is presented.
