Yes, there are several companies that offer repair services for ECU, ECM, PCM or whatever name the use. Most of the major auto parts stores have someone they use or you can contact Cardone, Car Computer Exchange, in NC, SIA Electronics in Illinois, https://siaelec.com/ and probably a dozen others. Call your local auto parts store and ask who they might use? I know Cardone requires you to take it to an auto parts store as they have no way to do payments with a consumer.
