What differences between V2 V5.017 and 4LED V7.020?

If you mainly want to work for 24V truck and tractor , 4LED V7.020 is more suitable for you !

1. Different Connection Way :

For V2 V5.017,it can read and write ECU via OBD2 Cable Directly for most vehicles,easy to operate.

For 4LED V7.020,it read and write ECU via TRICORE or BDM Or Other Mode with special cable, the software will guide you how to operate.

2. Different Vehicle Coverage :

For example: V2 V 5.017 and 4LED v7.020 all can work For Most for Toyota Denso ECU Protocol,But just 4LED V7.020 can work For Toyota Hilux kun26 very well !

4LED V7.020 can support much more truck/tractor/motorcycle than V2 V5.017 !

For Some cars. V2 V5.017 just can read it. But 4LED V7.020 can read and write it.
