On the 75/ZT the tool can currently access the following ECUs:-
MEMS3 for the 1.8 cars
EMS2000 for the V6 cars
EDC15C4 / DDE4 for the diesel cars
Jatco automatic transmission
ABS5.7 abs controller
Temic airbag controller for cars upto 2004.
Autoliv airbag controller for 2004 on cars
For each ECU if you click on the link you can see screenshots showing what the tool can do.
As someone above said, the tool does not have any features that can do any harm to your 75/ZT. If you want something reprogrammed or enhanced you will still need to find a T4 owner.
It doesn't quite cover the entire car but we are still in development and entire coverage is our intention.
