If you are already a MaxiEcu User and want to use our diagnostic software from a different brand than the one you have purchased, you can easily extend the scope of your license.

Before purchasing, please check the functionality search engine on our website to check the scope of support offered for selected vehicle parameters. The license as a digital product, in accordance with legal regulations, is subject to a limited right of return.

The purchase of a new brand for the MaxiEcu 3 software license (version for Windows 10 or newer, Android 8 or newer) – is possible directly through the User’s account in the LICENSES section. The license for the purchased brand is generated automatically after completing the order.


If you need a new brand for the MaxiEcu 2 software license (version for Windows 8 or newer) – please contact us via the request form in your User account. Tell us what brand you need and we will send you a link to order online. Licenses for the purchased brand(s) are generated by our Sales Department during office hours, i.e. on working days from Monday to Friday, between 7:00 a.m. and 3:00 p.m.

MaxiEcu 2 users who have an MPM-COM model interface – due to technological limitations, the MPM-COM interface model will not work with the MaxiEcu 3 software license.

  • option 1) do not replace the interface and buy a new brand for MaxiEcu 2 (to purchase – contact us via the application form). After purchase, you will have 11 brands under the MaxiEcu 2 software license.
  • option 2) replace the interface with the 4GEN model (to purchase – contact us via the application form). After purchase, you will have the new 4GEN interface and 10 brands under the MaxiEcu 2 software license. Then, you can choose to purchase an extension for either the MaxiEcu 2 software (to purchase – contact us via the request form) or the MaxiEcu 3 software (purchase via the User’s account).
  • option 3) replace the interface with the 4GEN model + switch offer to MaxiEcu 3 (offer in the User’s account). After taking advantage of the offer, you will have the new 4GEN interface and 10 brands on the new MaxiEcu 3 software license (the MPM-COM interface is removed from our database, but the MaxiEcu 2 license remains active on it).
