Autotune map for JB4 yet?

So I know the older version of JB4's for the N54/N55 had map 5 I believe for autotune. I really like the idea of this map constantly adapting to conditions and some of my friends have had great experiences running this map. Is there anything like that out for the B58 yet? I am reading the map guide and I don't think any of them qualify as "auto tune". Is it safe to say that an equivalent map has not been developed yet? I searched the thread on B58 JB4 and did not find a direct answer.

Can I safely run map 3 if I am stock other than a K&N filter and 93? Atleast on a cold day?

This might be a stupid question but to log you need a computer or bluetooth kit right? If I dont have access to either, anything I should look for while using it such as sputtering etc? Even with a log i am not sure what are the things to look out for

Yea. U would need a laptop or the Bluetooth connect kit. And as for what to look for in the log. You would probably get better feedback from posting the log on n54tech.

But if you are saying u have no way of logging the car. I would stick to map1 with your modifications until you can source a way to datalog

If you are not sure what to look for you should post it on BMS forum so they can check
