BMW ENET CABLE
In order to program and datalog your Toyota A90 Supra with bootmod3 you will need a BMW ENET Cable. Most cables are from cheap and fail due to the low quality. This is a Heavy Duty Ethernet to OBD Interface that we use and is known not to fail.
Most newer laptops do NOT have a Ethernet interface.
Laptops without ethernet interfaces will also need the USB adapter.
