Fuel trim difference between bank 1 & 2
Just starting the remote tuning process after swapping in 1000cc injectors on my car. Currently have the base map from Eugene loaded in the car. I’m noticing that the fuel trims between bank 1 and 2 are different.
Bank 1 reads normal at about 96-97% STFT, 100% LTFT.
Bank 2 reads ~106-108% STFT, 90% LTFT.
I was originally thinking that the trim for bank 2 is 10% higher from looking at the short term, but if you consider that the long term is 10% less, the banks are nearly identical. Weird
Is this something to be concerned about? Will the Bank 2 LTFT eventually go back to ~100% and then the banks will be equal in fuel trim?
I already looked for leaks (cigar-smoke tested intake.. nothing. Hose-to-ear tested intake manifold area.. nothing. No audible exhaust leaks)
