Hi all,
Yesterday I finally returned the car to closed loop with ltft enabled. The car is running much better than the last time it ran closed loop (as I've tuned as carefully as possible) but I have a few questions regarding the logs.
I'm now logging STFT and LTFT, the STFT average is 0.3% and the LTFT average is settled at -1.3% - is this good? The next is I'd like to see a map to show how the trims are at different rpm/manifold pressure - I presume I just create the map with rpm vs manifold pressure logged against the LTFT?
What I do see is a bit of difference between bank 1 (the bank I tuned for) and bank 2 but it isnt much and to be expected. Unfortunately I can no longer log my LC-1 as I had to remove it to plug in the narrow band (as I wanted to start returning the car to as stock as possible).
When looking at the stft and ltft trims what is a guidance to say its pulling or adding fuel, I guess a - figure is for rich and a + is for lean?
Has anyone ran the O2's in combination with PE mode? I noticed there is a setting for this and would like to know if it does help get a more accurate PE or is it not fast enough so better to use the VE table?
Cheers
