Dette verktøyet kan finjustere Yoshimura PIM 1 enheten. Dette er hva Yoshimura selv sier om FIMAK:
If additional tuning is required, the FIMAK is used to adjust the settings inside the Peripheral Interface Module (PIM).
This hand held unit plugs into the PIM and detailed adjustments to the maps fuel settings allow you to fine tune the engines characteristics. The FIMAK is simply the ultimate adjustment tool when tuning a race engine.
NB! Kan ikke benyttes for EMS PIM 2
