Hey guys need a little help. I was installing jb4 on my e90 n55. When installed, the engine shuts off when you try to go to command mode. I double checked everything.
What could this be?
Thank you.
(Tune has been previously installed before and this problem did not occur.)

Additional info: I have talked to another person on one of the BMW Facebook groups and he's having the same problem when installed with the flex fuel wires. He said he disconnected the flex fuel wires and it worked just fine. What could be a fix?

Double check the install. Make sure all sensors aerated snugly. If the double check comes out clean post install photos or email BMS tech support.
