Default Unable to change settings on JB4 interface - 10-10-2020, 07:37 PM

Hello,

I drive a 2011 e92 x-drive with an N55 motor / 6 speed manual. I purchased and installed a JB4 unit new back in 2015. I took it off for repairs and left it off until now.

I just installed the JB4 back on except I did the ISO mod to the JB4 unit and uploaded firmware version N55_ISO_5_17_T5.

The ISO mod made a huge difference in consistency. However now I’m dealing with a different issue with 3rd gear only hitting about 7-10psi while 1st, 2nd, and 4th will hit about 18psi on Map 5. So I figured out that I have to change a setting under User Adjustment on the JB4 interface (I’m still using a laptop for connection), but I’m unable to do so. 1st and 2nd Max Boost settings are set to “0” while 3rd gear Max Boost setting is set to “1.” I cannot change it to “0.” Every time I change the value to “0” it just changes back to “1” when I click off the User Adjustment tab and go back.

How can I fix this?

EDIT: I noticed that on the speedo menu I cannot get past 14 on the menu.

Thanks
