JB4 Tuning
Hey all! Today I installed a jb4 and want educated advise on which map i should run. As of now, my m2 has an aftermarket intake and catless downpipe. I always run 93 octane

My understanding is that it should be Map 2.

Terry recommends, do a log on map4 first (good logs) and then drive map1 for a while and do some logs see how your car reacts.
Since the M2 engine has higher stock boost than standard N55 (that the JB4 N55 maps) are configured for it will be a little different. Start slow first and post your logs on http://www.n54tech.com/forums/forumdisplay.php?f=35 Did you install the EWG-add on connector? Make sure you're on latest firmware before running map1 also, can easily be done via bluetooth with the jb4 mobile app. These below are the maps and for standard N55. Stock M2 runs 14-16 boost so you can see map1 or 2 can have you running higher boost than standard N55 with map5 or 7. Map 0: JB4 disabled Map 1: Additive target, around 4psi over stock. Map 2: Additive target, around 6psi over stock. Suggested for those with 93 octane and bolt on modifications. Also good for small E85 mixtures. Map 3: Progressive methanol mapping, absolute target of 11-20psi based on meth flow, meth additive setting, and average ignition values. Map 4: Stock performance with JB4 active for logging only. Map 5: Autotuning map, absolute target of 11-17psi based on octane and conditions. Map 6: User definable absolute target map. Suggested for troubleshooting by professionals only. Map 7: Race gas map. Absolute target of 18.5psi. Requires straight unleaded race gas. I'm running map4 when the weather is 90F+, dont need anything breaking and the stock power in my X4 M40i (Same engine) is more than enough for Daily. I run map1 with 93 and use map2 with e85 blends, and Map5 (while logging always). I'm running map5 as of today going to try it out for a week.

For the OBDii firmware and F platform codes last I checked on my m235, map 1 and 2 also have auto tune logic built in as well

There are no claimed gains, every car is different these days.
Manual or DCT, weather, fuel, full tank or 1/4 tank, different dyno (Mustang, Dynojet, etc) too many variables. The point anyone should do is Dyno before and after, or go with JB4 (adapted on map1 for a few good miles) Dyno first 2 runs and then Map4 as last run. If you don't care about gains then drag it lol Here's some of my Dynos with different Weather/Fuel and Boost Safety http://www.n54tech.com/forums/showthread.php?t=40636

Unless you know what your doing Map 5 could easily kill your engine...Letting users define AFR and Timing advance AND BOOST. Most even car people have no clue how these parameters affect each other and cause detonation. Most dont even REALLY know what detonation is...Scary...
Im an old JDM tuner that used to tune from scratch stand-alone systems and Im afraid to touch Map 5.... FSociety is smart too, hot weather like this, whats the point...stockkin it is the way to go...Once it cools down or I get a water/C02 intercooler chiller and bigger FMIC Im being conservative until at least the 60s

Not so - map 1 and 2 are additive maps and have limited initial learning which is based on DME adaptions.

What do you mean by this? I thought map 5s autotuning did all the work for you? No need for the user to mess with any parameters. On my 135i with DP I mostly ran map 5 which was especially nice when I swung by an e85 station and threw in a few gallons then had the tune auto adjust. Never had any issues.

Not sure why when I had my m235i then and emailed Terry he told me Map 1 and 2 have auto tune logic build in as well which is why he told me I could use small doses of e85 on those maps.. Maybe he mispoke
