  We study the dynamical regimes that emerge from the strongly coupling between
two Chua's circuits with parameters mismatch. For the region around the perfect
synchronous state we show how to combine parameter diversity and coupling in
order to robustly and precisely target a desired regime. This target process
allows us to obtain regimes that may lie outside parameter ranges accessible
for any isolated circuit. The results are obtained by following a recently
developed theoretical technique, the order parameter expansion, and are
verified both by numerical simulations and on electronic circuits. The
theoretical results indicate that the same predictable change in the collective
dynamics can be obtained for large populations of strongly coupled circuits
with parameter mismatches.
