different trims between banks, whats ok?

Hi all,
Im commanding 14.7 using 3647 and all is well. However if I go to semi open loop by commanding 14.63/EQ 1 my STFT trims differ by around 4% or more.

I need to add that Im running my LC-1 as an NB02 sim.

I have reverted to commanding 14.7:1 so that both banks get the same fueling.

My question is what is an acceptable difference?

Also I want to retain the WB if possible otherwise Id throw the OEM O2 back in. I seem to recall there was a difference anyway even with the stock 02's in.

Thanks

I have seen this diff in the stock O2's.

Tried swapping O2S between banks...?

Update on this is a reset to factory of the LC-1 now I only have a 2% difference. Im happy with that.

Do you mean "reset to factory defaults" or "free air calibration/reset"...?

Factory calibration. I had skewed it a little. I do a clean air recal every now and again, but it wasnt that.

Oh, okay, so that resets the NB sim tranfser function back to factory default and that causes the NB sim to behave better which reduces your LTFT difference;
good info, thanks. :rockon:
