Hmm... sorry - I've only worked with the 32bit roms, no clue about the 16 bit ones.

I think I've also found the rear O2 closed loop fueling target compensation limits - see viewtopic.php?f=34&t=8595

Hi,
now I wanted to give some feedback. So I had the AF # 3 is set to 0. The car now has a stable idle. And the ride is now smooth. Learning view looks good too. The first is the attachment with fully closed blow off valve after about 80 miles. The second I got 30% and 70% recirculating into the open after about 160 miles. More unfortunately, not going outside because I'm usually too many misfires. I hope that in the next few days my wideband O2 comes. Then again, I can create better logs. But I guess that's not much difference, since the twin scroll the lambda probe is moved into the downpipe.

td - I haven't forgotten about these yet. I'm just getting my MAF scaling ironed out a bit nicer and the rest of my tune fixed up first. I'll post up my results though!

No worries - the consensus is that with all of these AF3 and rear O2 tables zeroed, and the CELs switched off, the rich CL condition is removed completely.

td-d,
I saw on your other thread you are using a program to graph log files. Is that the same log viewer that NSFW wrote or did you get it from somewhere else? Looks handy.

Driven like its stolen most of the time and still get 600kms to a tank but highway cruising, the Forester is great on premium fuel with lots of overtaking. AF3 was the missing piece of my puzzle! My best is 6.4L/100kms on a 60L tank... I use the throttle for effective EGR, in conjunction with avcs to keep IPW low and crank torque high.
