Bmw m52 timing settings

[Denso]

Hi for all

I have timing gun trying to setup my timing

It gives in timing before tdc runing smooth when i close table it will be advanced after rpm raising i want to know if my settings are ok

Trigger offset is a bit odd for a BMW.  So with that base timing screen open and the engine running, your timing light shows the timing marks line up at 5 deg BTDC?  And if you rev the engine with the set base timing screen still open, the timing mark stays solid at 5BTDC and doesn't drift away?

No when i raise rpm it goes after TDC abit and engine smoothly

If the timing drifts more than say 1 or 2 degrees with RPM that would suggest something is wrong with your trigger or trigger setup.  You would really need an oscilloscope capture to determine the problem.
