Tech Spec Addendums

Every option control and modification for our ECUs has an addendum for the technical specification, which we will send upon request. If your ECU contains a modification or option, please contact OpenECU support to request the addendum.

If you are not sure if your ECU contains a modification or option, most likely it does not. You must specifically ask for the mod/option and pay extra for it. However, here is a guide to help you determine if you have an option or modification.

Your ECU has an option or modification if any of the following are true:

• Your ECU is something other than an M110, M220, M250, M460, M461, or M670
  • For example, if you have an M210
• You paid extra for a modification
• Your ECU part number (on the label) contains "modX", where X is a number.
  • This is for older ECUs. Recently the part numbering scheme changed - see the next bullet point.
• The last two digits after the 2nd dash are not 01 OR the last three digits after the 3rd dash are not 000
  • Example, your part number is 01T-068276-0102-001.
    • The "-0102" shows that you have mod 02 (the last two digits after the 2nd dash show mod level).
    • The "-001" shows you have option 001 (the last three digits after the 3rd dash show option).
