The tool supports using a variety of Vector CAN cards. The tool defaults to using a CANcardX interface, but can connect to others using the following options: -cancardxl or -pci.

The options are added to the command for reprogramming, so as an extension to programming an OpenECU device with the step1 application, choosing the AC2 PCI option would be:

oe_freeccp -pci -f step1_image_small.s37
