N52B30 in different version 1/X3/X5/6series

Hi Everyone,

I would like to bring one question which is in regards to this engine - N52b30 and IS there any difference in different models.

For example the same engine :
190 kW Applications:

2008-2011 E89 Z4 sDrive30i
2009-2011 E84 X1 xDrive28i
2009-2012 E87 130i
2004-2008 E90/E92/E93 330i, 330Ci, 330xi
2005-2009 E60/E61 530i, 530xi
2004-2007 E63/E64 630i
195 kW Applications:

2005-2008 E85/E86 Z4 3.0si
2006-2009 E87 130i hatchback
200 kW Applications:

20062010 E83 X3 3.0i
2006-2010 E70 X5 3.0si, xDrive30i
2007-2010 E63/E64 630i

Is there a way to change my software on the E90 330i with the one from 6 series so I can use the obvious full potential of the engine,my car is EU spec so i dont think there are mechanical differences between mine and 6 series engine.

Any ideas?

Be careful that you aren't comparing to the N53B30.

The factory tunes are basically identical. It appears to be the exhaust that is different on the higher output engines (like the 3.0si), giving them slightly more power. But you aren't going to get that by flashing to a different software.

Also, you couldn't take the software from an E63 and just flash it to your E90. There are a lot of parameters for each specific chassis, that would be incorrect for the E90. It probably wouldn't start or would be in limp mode with errors.

A friend's X5 N52 had oil cooler attached to oil filter housing and a different water pump with plastic propeller housing similar to 335 engine's.
