LT for banks in fuel trim is constant, is it a problem?
Well, I am beginner in the data logging world of cars (but not to oilfield data logging 
), anyway, I have noticed that the LT on all banks that I can get thier readings are always constant on -09.4, +00.0, -50.0, for B1, B2, and B3 respectively. Also, B4 is always 00.0 for both ST and LT.
Is there any problem?
I run catless, no cats for primary or secondary.

Are you throwing any 02 sensor codes? Your STs should bounce around... as to a degree so should your LTs. They definitely should not be static. Also, -50 for LTs is ridiculously out of this world high. Realistically your LTs should be under +/-5 and go to 0 at WOT pulls. What are you datalogging with? Is the car running fine? afrs solid?

Well, I am using Dashcommand for Iphone as datalogging. Today I noticed that LT is changing but after long time and in small range. LT is in range of 44.00 - 47.00 today. B4 is not functioning always 0 for both ST and LT, do we have B4 in our cars?

LTFT should be as even as possible between banks and as close to 0 as possible. At least within 5% range .. Any reading of +25% or -25% will set a code and for good reason too.
