Can't get off low octane timing table...

[odd boy]

Well spoke a little too soon. The O2 sensors smoothed it out a bit and got rid of the heater codes, but now its back to adding 16-17% fuel on bank 1 and 5-7% on bank 2. I have checked all the coil packs and plugs as well as checked for intake leaks. Can't seem to find anything, but I have a slight exhuast leak by the collector ( crappy clamps from previous owner ) and am wondering if the leak is enough to make the O2 sensor read a bit lean...?

I don't think. I saw the injectors duty cycle are different, why don't u clean them??

Last thing, force open loop and remove the O2 sensors!!!

Maybe you have an air leak on bank 1.

Also, is it just me, or is your B5910 trying to pull 6° (see image).

I think, on that table, it will only pull out 6 deg. if the engine temp is over 240+ deg... I am running around 192 deg. It does look like that table is pulling out quite a bit of timing at a low temp idle/part throttle scenario... Is this pretty common? I am working off a mail order tune that the car came with...

Oh, I just realized I fell into the mismatched units hole (140F was being treated as 140C)... lol......

... I fixed my units configuration, and now I agree with you, please disregard my post #12.

No problem ... I did another log after tweaking a few things and I got my timing back, but still can't figure out this lean issue on bank 1

- see attached log...

If you have a leak on the bank 1 collector, that may be sucking in air (each pressure pulse is followed by a "vacuum" pulse).

Even small leaks are enough to throw of the O2's been there done that. Fix the leak then relog fuel trims. If you don't you'll be like my dog chasing its tail > getting nowhere fast!
