Exclamation Help! --> JB4 Fault codes & Map 6 Log Review - 09-09-2018, 09:24 AM

Hello and thank you, in advance, for your help!

Asks:
1) I would like feedback on my logs and any recommendations for adjusting my Map 6 settings.
2) I have read/researched that the fault codes, and the resulting CEL are not an issue as the JB4 disregards them as long as not in map 0. This seems accurate as despite the "120408 Reduced power mode" the car still pulls like a train. My Question...Is this accurate, or do I need to get a code reader and clear them out?
3) Is there any type of patch or solution that will let the JB4 clear codes?
4) REGARDING #3... I know this a widely contested issue, and I have read both sides, ad nauseam. I am just looking for a simple yes/no... please refrain from turning this thread into another battle of opinions, as it truly prevents the contribution that you guys/this community are so good at providing.

I was driving my car somewhat spiritedly (7/10ths) in colorado from a base elevation of 5,600' to 10,300 (somewhat linearly over a ~90 min drive) and at a WOT part of the drive (~8,000' elevation) and my CEL came on (not flashing, just solid) -- I have not had any CEL problems with my down-pipe -- and I got the the following fault codes that appeared...FYI: I was in Map 6 (settings screenshots attached)

Fault Codes:
139001 No Description Found
118001 Mixture ECU: mixture too lean
102001 Air mass, plausibility -- Tuner code, ignore
123511 Wastegate Flap Sluggish
120408 Reduced power mode[/B]

Mods: (2016 340i xDrive, 7,500 miles)
- JB4 with EWG & FF connections installed
- M-Sport Exhaust
- VRSF ***-less down-pipe with right-angle O2 extender installed on rearmost sensor.
- Agency Power Intake
- OE Spark plugs
- Running 91RON with 2.25 gal of e85

A bit confused by the questions. Why would deleting codes be hotly contested? There was some change in the newer BMW B58 software that broke the code deleting option. Not just for the JB4 but for OBDII tools and most other diagnostic tools as well. We're working on a fix. So if you delete codes with ign on, engine off, and they don't clear, then there is nothing you can do at the moment for that.

If nothing is wrong with the car, there should be no codes though, so you can address each fault and correct whatever is triggering it. Not being able to delete just makes it more time consuming as normally first thing you do is delete all codes and see what comes back so you know what is actively wrong.

For starters I'd kick over to map2 and evaluate. Normally not a fan of map6 absolute target profiles on the B58. Mixture codes are probably from a combination of the mods and E85 fuel.
