Mercedes ME9.7 ECM Cloning Service

Mercedes ME9.7 engine computer cloning

This mail-in service programs a compatible used Bosch ME9.7 engine control module for Mercedes applications with M272 V6 or M273 V8 engines. ECM and ECU are common names for the engine computer. Select the replacement-module option that matches your engine, or supply a compatible donor.

Compatibility and what to send

Check the ME9.7 identification and part numbers on the original ECM. A vehicle badge, model year or similar-looking case is not enough to confirm a replacement. If you are buying your own donor, have us confirm compatibility before purchasing or shipping it.

• Original ECM communicates: send your original ECM and your compatible donor, unless you select a replacement ECM from us.
• Original ECM is unreadable: select the EIS-based programming option and send the original Electronic Ignition Switch (EIS) instead. This option adds $50; confirm the application and package contents with us before shipping.
• Need a donor: choose the 272 ECM V6 option for M272 or the 273 ECM V8 option for M273. The listed used ECM options carry a two-year warranty.

If you do not know your engine or module type, call/text (818) 510-3375 with your VIN and module-label details. Other controller families have their own ECM cloning service listings.

Check communication before choosing an option

The existing ME9.7 service uses communication with the original ECM to choose the cloning route. With a suitable diagnostic scanner, check whether you can access the engine module, often labeled ME (Motor Electronics), and read its fault codes. No communication can also involve the vehicle's power supply, wiring or network, so diagnose the fault before assuming that the ECM needs replacement.

Watch our ECM diagnostic video. You can also watch our ME9.7 cloning demonstration for M272 and M273 modules.

ME9.7 cloning questions

Is a replacement ECM included in the base price?

No. The used M272 V6 and M273 V8 ECMs are separate purchase options on this page. You can also supply a compatible donor. Review the selected options and subtotal before checkout.

Can you help if my original ECM cannot be read?

This ME9.7 listing offers programming using your original EIS for an additional $50. Select that option and confirm your application with us. This is separate from ordering an EIS replacement.

Does a no-start mean I need ECM cloning?

No. Identify the failed component first. If your diagnosis points to the ignition switch or steering lock, review the separate EIS cloning or ESL emulator programming services.

Will cloning add horsepower or improve fuel economy?

This listing is for replacement-module programming and cloning. It does not advertise a performance tune or fuel-economy upgrade.
