I tested reads on a BMW E90 330d (Bosch EDC17CP02) and a VW Golf 5 GTI (MED9.1). In both cases, the software correctly identified the ECU, boot mode, and protocol without a single error. The read speeds via CAN on the BMW were impressive—full 2MB flash in under 4 minutes. Writing a modified file back took around 5 minutes, with checksum verification happening automatically.
