Question BMW 135i N54 JB4 + Pump BEF want to Temporarily go back to Stock ECU Flash - 08-23-2020, 09:15 AM

Hi Guys, quick question, I have a BMW135i N54 with JB4 + Pump BEF, I used the MHD App to flash the Pump BEF but I want to temporarily go back to Stock ECU flash for a couple of days, my question is

Would it be okay if I use the MHD App and
“flash to Stage0 (stock power)” (+-2min flash)and then set steering control to 4/3


Do I have to fully uninstall MHD and
“flash back to stock” (+-35min) and then set steering control back to 4/3

Please let me know if I can do the quick 2min. stock map option or do I have to go the long way and fully uninstall MHD.

If anybody could please let me know, thanks
