MEFI 5 | 6 | Delphi Refurbished ECM

MEFI 5 Marine ECM ECU  Programmed | Replacement part

Professional marine ECM cloning service for 12597744 and compatible Delphi-based control modules. We recover the usable data from your original unit and prepare a programmed replacement ECU for $2,950 when cloning is possible.

This service is designed for boat owners, marine technicians, and repair shops that need a dependable solution when the original controller is damaged, not repairable, or no longer communicates. The goal is to supply a replacement unit prepared from your original calibration so installation is faster and avoids unnecessary dealer programming delays.

MEFI Programmed Replacement ECU — $2,950

If your original marine ECM cannot be repaired, we can often clone your original data and sell you a programmed replacement ECM for $2,950. This helps preserve engine-specific calibration information and reduces the risk of installing an incorrect or blank unit.

What We Transfer When the Data Is Readable

• Engine calibration data
• Module configuration details
• Application-specific programming information
• Original controller data required to prepare the replacement

Your original core is required. We cannot prepare a cloned replacement without the original module. If the required memory area is readable, we transfer the recovered information into a compatible replacement controller and test the unit before shipping.

MEFI Compatible Marine Applications

MEFI 5 and MEFI 6 controllers are commonly used on GM-based marine engines in many inboard and sterndrive applications, including:

• Volvo Penta marine engines
• MerCruiser applications
• Indmar engines
• Crusader engines
• Marine Power applications
• Other compatible Delphi marine ECU systems

When Cloning or Replacement May Be Needed

• The original MEFI ECM is not repairable

How the Process Works

1. Ship your original controller to us.
2. We inspect the module and attempt to read the data.
3. If recovery is possible, we program a compatible replacement unit.
4. The programmed ECU is bench-tested before shipment.
5. We return the replacement ready for installation whenever the cloning process is successful.

Important Note Before Ordering

This service requires your original MEFI 5 or MEFI 6 ECM. Success depends on the condition of the module and whether the required data can be read. Contact us before sending your unit if you are unsure about compatibility, symptoms, or part number identification.
