need advice for JB4

Hi,

I had the cahnce to buy a F Series N55 JB4 Stage II with USB Cable, EWG Harness, and Flex Fuel wires from a member here.

I have a candian 2015 m235xi auto.

In only plan to use map1 : only 91oct , no other modsé

For the install, do I need to get the lastest firmware and the lastest maps? If yes, where I can find this?

It not clear here. http://ift.tt/1GWiypL
there are 4 .hex files at the end of the thread. Which one to choose?

I can't find the maps.

Do you have any recommandations? What about the drivability? I hope something more powerful when I floor it but very smooth and drivable for normal driving.

thank you very much
