I have seen the information I am asking in bits and pieces all over pertaining to the different maps and there purpose. I tried searching briefly and didn't come up with anything that was recent.

I just installed the JB4 today and would like a better understanding. I'm sure this information would be better focused at Terry but thought the information being posted here and consolidated would be great.

Map 0: JB4 disabled.
- I don't understand the difference with map 0, 3 and 4
Map 1: Peak boost 20psi, suitable for most racing applications
- Would this be for completely stock? I ask cause I am stock at the moment
Map 2: Peak boost 21psi, suggested for those using exhaust modifications and 93 RM2 octane or higher fuels
-This is the map I will be running when I get my downpipe install...hopefully this weekend!
Map 3: Disabled
- See map 0
Map 4: Stock performance, JB4 on
- See map 0
Map 5: 320i/520i map. Peak boost 17psi.
- I understand this one
Map 6: User definable map. Suggested for troubleshooting by professionals only.
- I understand this one
Map 7: Race gas map. Peak boost 23psi. This is a fairly aggressive map and increases engine damage risk. Use with caution.
- I will be using this map when I run an e85 mix w/downpipe only
