For those running the JB4 with a backend flash, can you still set the JB4 to map 0 to put it back to stock, or do you also have to remove the backend flash? Say for example if a family member needed to drive your car, and you wanted to put the JB4 in map 0...

for stock performance you can use map 4...
if family member is a teenager use map 8 HAHA

car acts a bit funky (but still drivable as DD) when JB4 is off and flash is loaded.

How about running 91 when your back end flash is designed for 50/50 e85/91??

It’s very unlikely that you will do damage because as the JB4 targets lean conditions (because it thinks you are running alcohol) once it detects knock it will just pull boost/timing to compensate.

If your flash is designed for 50/50 e85/91 and you only have 91 I would refrain from going WOT and just take it easy driving around

Thanks for input... It's just easy to always run 50/50 with stations not very abundant
