Default N54 Reverting to MAP4 - 05-04-2021, 03:16 AM

Hi Guys,

New to the Forum.

I have a 2008 135i with the following mods, Intake, DP's, full exhaust, hybrid turbos, upgraded diverter valves, single mass flywheel and JB4.

The JB4 keeps reverting to Map4. I have attached two logs. One where it was pulling fine and the second where is reverts back to Map4.

It will also pull the timing back to 0. Not sure where to start as I am new to this whole setup.

Thanks in advance.

Neither of those logs jumps to map 4, maybe because you raised the boost safety to 23? That's what your last safety was for.

Hi Steve,

Thanks for your reply.

I will do new logs and submit.

During a pull for instance in 3rd, everything will feel normal. After the pull the blinkers will flash twice. When I look in command mode under Speedo 0, the Tach will be on Map4. If I change it back to Map2, do another pull it will do the same. Look in command mode and it will be back on Map4.

I haven't changed any settings yet. I just recently bought the car and I am trying to figure out what the previous guys have done.

It will do the above on any Map, 1, 2, 5 and 6.
