Default Help, JB4 keeps dropping me from map 8 to the safety map - 07-10-2020, 11:37 PM

Hey everyone;

first off i just want to start by saying i JUST got my JB4 installed a week ago, so i'm new to this system and still learning how to properly set everything up. the issue i'm running into is my jb4 keeps dropping me from MAP 8 down to MAP 4. I know it isn't my boost limit because that caused it a few days ago so i brought my fail-safe up to 25 lbs, nd when i look through my logs the highest boost i hit during my 3rd gear pulls is around 20-21PSI and i verified that nothing had changed with my fail-safe. I have no idea whats causing it and could use help on how to set this all up proper so this doesn't keep happening. i'll attach my last log to this post.

I drive a 2015 BMW 650i X-drive with ******* *********, custom open exhaust, MAF delete, WMI and JB4

thanks

Bank2 boost is going well over target.

As a test could select WMI page bit3 DTML WMI input which would invert the boost control banks.

Thanks for getting back to me. I tried that today, meth doesn't even fire when I select that and the issue is still there other wise. I tried again today and get soon as I started pulling for any period Of time it booted me back down to four. I'm going to attach my log from today's pull to this as well, I'm sure it's going to say the same as yesterday but just in case. I'll also include screenshots of my current jb4 settings just in case I have something wrong there.

You did not enable the WMI bit3 setting I asked for. No need for photos of settings CSV has it all just be sure to start a new log batch every time.

Change the boost by gear values to 0 and be sure the pedal is 100% down when logging.
