I need a help, I am new here, owner of F30. I installed new battery, and need to reset computer. Also I would like to turn off Start/Stop option. I bought Ethernet to OBD cable for F30. Now I need to install ISTA-D or ISTA D +. What is the difference and which version ? What is PSdZData ? Can somebody point me to correct link and what is needed to download to reset battery and turn off Start/Stop button. I am newbie. Thank you.
