The ECU, MEFI controls all engine functions including spark, fuel, idle speed, and rev limit. MEFITUNING has dyno tested multiple engine combinations and has the knowledge to offer you a base tune to start with. If you are planning to make any modifications or already have, the ECU re-calibration is necessary for proper control of the engine.
