Pick your chassis and get the E-Sys target (project) to connect with. Free, no account needed.
When you connect to a car in E-Sys, you choose a target (project) that matches the car's platform: F001, F010, F020, F025 and F056 for most F series cars, S15A, S15C and S18A for G series cars, and I001 for the i3 and i8. The target has to exist in your PSdZData; with the wrong one, E-Sys can't read or code the car's ECUs.
Not sure which chassis your car is? A VIN Search shows the chassis (e.g. G30), the I-Level and the full ECU list.
