I'm new here and I just installed a JB4. I have a 2016 340i with a c@tless dp , an open element intake and a XHP stage 3 transmission tune. I did a few pulls yesterday in Map 1 and 2, it was alright (I didn't log those). Today I some pulls on Map 2 and 3. I have 91 octane fuel and a e85 fuel station half an hour from home. I wanted to bump up my octane so I did 3 gallons of e85 and 12.8 of regular 91. The pulls felt super good in maps 2 and 3 and I just want to make sure everything looks good on the logs. Two to three times it kicked me into Map 8 which Im assuming is limp mode and not sure why.
