MEFI Calibration and Hi Performance Engine Services

MEFITUNING offers full engine services include custom engine building, high performance parts sales, and performance engine tuning on the DTS 4000 dynamometer. The DTS 4000 dynamometer is capable of handling engines rated up to 3,000 HP, 2,500 pounds of torque, and 15,000 RPM. We can monitor up to 100 points of data in a controlled environment.

Have you modified your stock Mercury MEFI Engine with a high performance exhaust, bigger cam or have you had it supercharged? MEFITUNING offers performance calibrations for your MEFI 1, MEFI 2, MEFI 3, MEFI 4, and MEFI 4b Electronic Control Unit (ECU) supporting the modifications you have made.

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.

We offer a service much unlike the other competitors. Once we send you a tune we will follow-up with you and make any necessary changes. We bring the tools to you. We offer onsite service covering KANSAS, OKLAHOMA, MISSOURI, NEBRASKA, and TEXAS. We love going to the lake and applying our tuning technique; when you are happy so too are we!
