Agree!!!
My question is how does Eminhello gets his car to the redline (engine will cut out IN the redline)?? Shit, what am I doing wrong? I have a heavillymodded 335 with Jb3 and have NEVER needed to get into the redline not even close to win a hectic race. My races are normally done and dusted long before the needle hits approx 5500rpm.

However, we had one case of a faulty JB3 control box that gave limp modes from map 3 onwards but nothing when JB3 was disconnected. But this was quickly fixed when terry shipped a new control box a day or so later and the car was back to amazing again.

You have two options. You can follow everyone's advice and contact BMS for help, which you should have done in the first place, or sit around and continue to have problems. No one here, including myself, knows what your problem is. We will never know. You need a scan and a proper diagnosis from the professionals.

Believe me, when you race with your modded 335i, don't turn off the dtc all the way..

my car only went to limp mode when i turn the dtc all the way..only

believe me or not, this is my solution for me..

just my 2cents
