First of all, I need to know what ECU you exactly have. Could you please send me the following information to my e-mail address?
ECU serial number
SW code version in the ECU
Version of CalTool or DescPro
Bear in mind that ECPro is an obsolete product which is no longer supported. However, we should be able to change the developer which enables you to work with the ECU without a dongle. This is also not free of charge and you need to send us the ECU. After that process, the ECU will be completely blank.
SQ6M questions can be directed to me as well.
