Caveats

In 2022–2023 AMG models with MED17.7.5 ECU, there is a significant risk—approximately 30%—of bricking the ECU when programming via OBD. Because restoration can be nearly impossible if this occurs, we require the ECU to be sent to Morendi for a full write using specialized equipment. Programming for these cars requires additional services above and beyond this base tune. This includes a Stage 1 or Stage 2 tune, with options for extra features such as Pops and Bangs or cooling modifications. Please contact us if you have this configuration and we will create a special tune service for you. Approximate cost is $1,200.
