Coarse-grained simulations are often employed to study the translocation of DNA through a nanopore. The majority of these studies investigate the translocation process in a relatively generic sense and do not endeavour to match any particular set of
experimental conditions. In this manuscript, we use the concept of a Peclet number for translocation, $P_t$, to compare the drift-diffusion balance in a typical experiment vs a typical simulation. We find that the standard coarse-grained approach over-estimates diffusion effects by anywhere from a factor of 5 to 50 compared to experimental conditions using dsDNA. By defining a coarse-graining parameter, $lambda$, we are able to correct this and tune the simulations to replicate the experimental $P_t$ (for dsDNA and other scenarios). To show the effect that a particular $P_t$ can have on the dynamics of translocation, we perform simulations across a wide range of $P_t$ values for two different types of driving forces: a force applied in the pore and a pulling force applied to the end of the polymer. As $P_t$ brings the system from a diffusion dominated to a drift dominated regime, a variety of effects are observed including a non-monotonic dependence of the translocation time $tau$ on $P_t$ and a steep rise in the probability of translocating. Comparing the two force cases illustrates the impact of the crowding effects that occur on the trans side: a non-monotonic dependence of the width of the $tau$ distributions is obtained for the in-pore force but not for the pulling force.
