2009 - 2012 Mercedes Benz S350 W221 OM642 3.0 - Performance ECU Tuning

Performance Flash Tune for 2009 - 2012 Mercedes Benz S350 3.0 OM642 with EDC17CP10 ECU.

  • 2009-2012 S350 W221 CDI OM642 Diesel

    Stage 1 tune - +30WHP +40WTQ at the wheels.

    Performance tuning modifies torque limiter maps, boost levels, fuel maps, and more. All to help safely increase HP/TQ, while keeping good drive-ability and factory fail-safes/limp protection in place. Factory emissions remain functional and are not disabled. Gains can vary on vehicle condition and location.

    • We do not offer EGR - DPF - DEF disable/delete/bypass tuning.
    • We do not offer tuning services to the state of California.

    We have 2 methods of having this tune installed (Flash Type Selection).

    BENCH: Remove the DDE/ECU and mail it in. We will create a full backup image of your ECU without opening the lid or any physical damage to the ECU at all. We then upload our tune and mail the DDE/ECU back. This is the safest way, as we can have a full backup of the entire ECU content.

    REMOTE FLASH: No downtime!!! With this option, once an order is placed, we will ship you a cable, that cable connects to a laptop and we are able to remote into your computer to flash the car. The remote flash option includes the cost of the cable (which is yours to keep). If we are out of cables for remote flashing, we can offer a cable for rent with a deposit. (We will message you if this happens). In some cases, not all cars can be flashed this way. In that case, you will have to ship your ECU/DDE to us. *You will need a Windows 8 or newer laptop and WIFI to flash remotely (Apple, Chromebooks are not supported)*

    Please print out this form and mail it in with your ECU. ECU will not be flashed until the form is filled out and sent to us. Thank you.
