JB4 Questions

Hey guys I just bought a JB4 and I got a couple of questions. It's still coming in the mail but I wanna get everything out the way beforehand
2016 C450 AMG - Muffler Delete

1. How much E85 can you run with JB4?
2. E20, E30, E40. Are those percentages of E85? So like 10 gallons of fuel with E40 would be 4 gallons E85 and 6 gallons 91
3. What's the process of data logging?
4. I heard the car needs time to adjust to each map before you start going hard on the throttle. Not sure if this is true. If so, how long does the car need to adjust

Please give me as much detail as possible. Thanks in advance!

Up to 35% E85 is what we suggest. Usually people pump in 5-6 gallons rest pump gas for example.

Check the link above for addl details on how to log, how to read logs, and other mode advanced stuff, if you're interested in it.

The vehicle and JB4 each adapt during WOT runs. Takes a run or two for maximum performance.

Yea bro I installed it a couple of days ago and it's amazing. I'm running E85 at 30% and the car pulls hard. Even in map 1, you notice a slight change.
