E-Manage system is a “piggy-back” type unit.
An optional communication software package (PC Windows) and harness kit is available to fine tune the entire engine, from 16 additional fuel RPM points, ignition timing, larger injectors, airflow meters, injector duty cycle, and control up to 2 sub injectors.
