  • Part Number

    You ABSOLUTELY must match both of the following part numbers for this process to work:

    A 113 153 54 79

    0 261 208 361

    If your current ecu does not match both of the above this chip swap service DOES NOT WORK!

    how the process works?

    • You will need to send us your ecu.
    • We will first verify a part number match. We will then determine if your ecu can be worked on or if it is damaged beyond the point where we can swap all necessary circuit board chips. 
    • We will swap the necessary chips, test the donor ecu and confirm in working order then ship BOTH your original ecu and the new ecu back to you.
    • Installation instructions are below.
    • **NOTE** If the ecu sent to us is not a part number match we will ship it back but will have to charge a $24.99 handling fee and we will not be able to refund shipping costs. If the ecu sent to us has noticeable heavy water damage in the pins and we cannot remove the necessary chips we will ship the ecu back to you and there will be a $24.99 handling charge plus shipping. 
      **NOTE** There are some instances where this process does not work. It is not a 100% gaurantee but we have had great success with this process. If you are thinking of cloning your ecu please move forward with that. If we attempt this swap/repair and it doesn't work you will not be able to clone the ecu.
