Where are the manufactures going with the latest modules and ECU's. Will they be throw away or worth repairing? If so how is one to keep up with all the manufactures software to reflash or update? Is there a one stop shop that I don't know about to flash and program besides OE software.
To see this working, head to your live site.
No there is not a one stop for all programming.You will need access to all diff manufacturers websites that you plan to work on.You can either pay yearly or some you can purchase daily access.
