Map 1 and 2 have small autotune adjustments like all maps. You will run up to the boost limit designated by the map. Your boost may not hit the targets. It will auto adjust and/or look at FF, PWM, FOL, IAT, avgIGN, etc to determine actual boost up to the targets designated by the map.

M235 and M2/X4 M40i have different boost from stock.

Map1 on M2 is like Map5 or 7 on M235
Map2 is def going to run like shit on 93, its a must to have DPs and e85 blend for this one.
** Requires EWG-add on connector not included in JB4 OBD2 so need to be purchased extra for Map2+ **
Map3 - Meth Map
Map5 stutters and is not smooth w/o EWG-add on connector (Keep this in mind, if you intend on running map1 or 2 only you will be ok )
Map6 (Custom Map, Require Expertise in Tuning and JB4 parameters) (i wil be using this one for my Backend Flash and it will be my Race Map)
Map7 on M2 will def require EWG-add on and e85 blend (not recommended for 93 applications) in my opinion after testing it and Terry seeing my logs

User Adjustments
Boost Safety: 18 on M235 is fine but for M2 and X4 M40i needs to be raised to 20-21
I agree any map will run according to your cars condition (FF, FOL, iAT, avg_ign)

Thanks for the clarification Rob, I am experienced with JB4 going back to my e92 days but all this F series M235 and M2 firmware and maps confuse me because I still think back to the e92 maps.. So since Terry hasn't developed M2 specific firmware will map 1 and 2 still target the same amount of boost it would on the m235 or will it realize the M2 starts off with more boost and add on to that?

Correct, Terry hasn't developed nothing M2 specific yet.
So the JB4 will work as it would on a normal N55, map1 will add 4psi over stock (whatever the M2 makes at that location/weather/condition) and so on.

My map1 hits 18psi and spikes to 20, my Map2 18-20 as well.

Now here is the real question, when the M2 is in overboost does the JB4 up the boost throughout that time as well? That's why it confuses me how the M2 doesn't have its own firmware because the M235 doesn't have overboost

Map 1 is additive whereas maps 5 and 7 are both absolute - your note may be misread by others thought best to clear it up.

At present map 1 is all that's recommended and upping boost cap beyond 18psi needs to be done do knowing that m2 charge pipe is the same as m235i. Some have failed on m235i at 17-18psi hence my words of caution for m2 users.

For additive maps - jb4 would stack up on the over boost function hence why BMS are saying stay with map 1 for the time being. I think map5 auto tune current SW will struggle with overboost as I think I read that jb4 was defaulting to map 4 during testing.

BMS m2 FW will no doubt allow jb4 to address overboost

Even with map 6 (user adjustment) you can basically only adjust boost (boost target and duty bias) and fuel trims (through FOL). The most common issue I've seen is people maxing out trims and causing a lean AFR. Usually caused by too low of a FOL settings and/or too much boost. BMW has it's own fail safe when the fuel pumps fail (fuel pressure too low).

While you can do harm with map 6; it would be very difficult to do. You're right though; I've seen some scary user maps. Take it slow and do lots of reading and you should be good.

installed the jb4 on the M2 week ago, map1 hits 17.5 - 19 psi, I run it on map0 it hit's 14.5 - 15 psi but i realized the jb4 is disabled, i see catless downpipe code and tuner code ignore from map0, the next week ill install the methanol then ill run it 18-19 psi all the time.

* map4 is the best map for 93 oct after install the Dp,intake,cooler....

** If any one want to tune the M2 you won't see a big difference over stock till u run meth or race gas or pure stg2.

But still there is a noticeable difference?

Also which fuel did you use on map1?

Map1 will hit whatever your car condition/target will allow it to up to 4psi over stock - I've tested this for a few weeks and if your boost safety is at 18 (default) like it was on my car you will hit safety (map4) a few times, so increase Boost Safety on M2/X4 M40i is a great way to start adjusting your JB4 settings from day 1.

I've posted all the map info on page 1 on this thread or you can also find it here
http://www.n54tech.com/forums/showthread.php?t=18588

As other have said map4 is OEM Performance w/ JB4 active for logging

Here's my 4455lbs (Driver + Full Tank) weighed X4 M40i with the same M2 engine except no DCT or Overboost

347whp/339wtq on 93 pump (stock)
355whp/376wtq on map1
371whp/395wtq on map2
These runs were with 0 adaptation since I wanted a realistic idea
http://www.n54tech.com/forums/showpo...84&postcount=2

Then you can see here with hotter weather and humidity but a little e85 goes a long way both in 4th gear and 5th gear.
352whp/351wtq in 4th gear
382whp/412wtq in 4th gear map2 & e27 blend

the stock boost about 15psi, 3-4 psi over will be 18-19 psi to run this boost u need meth or race gas.

u hit 347whp stock then 355whp for map1(pump gas93), how the hell u can feel the difference of only 8whp gain!!

like i said on race gas or meth u will feel the difference.
