Launch X431 Xprog3 with GIII is used to  program Benz/BMW/VAG/Porsche keys and clone or replace ECU/TCU modules.What’s the difference among Launch X431 IMMO Plus,IMMO Elite,X431V+ and X431 PAD VII with Xprog3 ?

difference among launch series

difference among launch series

In sum:
IMMO Plus has the same key programming and ECU/TCU clone functions as IMMO Elite.The difference between these two is that IMMO Elite has basic diagnostics but IMMO Plus has full diagnostics
IMMO tablets support newer vehicle immo programming,i.e Volvo pre-2022,Toyota pre-2022,X431 V+ and PAD VII do not.
PAD VII supports online programming, others do not.
To clone or replace ECU or gearbox TCU with X-prog3,your tablet should have the ability to connect via USB.Lanuch X431 V+ only connects via Bluetooth, so X431V+ with GIII can not clone ECU/TCU.
