Hello There,

I am a beginner in this so I am happy for every answer that brings me further.
I've got a 2002 Volvo S80 T6 with Bosch me7.0 ecu. It's been remapped by Bhpmotorsport for more power.
Tho now I want to make some kind of pop&bangs and bring myself into the world of tuning. I've watched bunch of tutorials and forum posts
Bought a knock off KessV2 with all accesories and a MPPS v16. I thought it's gonna be pretty easy to read and write the ecu over OBD II.
Tho the ecu requires Boot Mode.
Now my question is what do I need to start reading and writing directly from the ECU? And what are the most important things I have to take care of. Thanks!
