WTH does that mean?

That's normal with oft tunes, it means oft has corrected the checksum of the rom. If you never saw that before then you were not uploading tunes correctly

Ok so i started from scratch and it looks a whole lot better now. Can u tell me if this looks stable though? may i still have an exhaust leak based on what you see? is my tune flashed correctly now?

Ok that's looking heaps better AFR is normal and ltft seems to be ok but its going to -100 off throttle and IAM alternates between 1 and 0. I think that's bogus and just a logging problem with OFT, they have a couple of issues at present with logging of some roms.

looking at KC Learned it appears knock is fine and IAM is not in fact 0

but it looks like your running an E85 tune now, even though logging of some parameters is a bit suspect.

You need to get onto the oft guys so they can sort out that logging as its difficult to read too much into it with the suspect parameters, but it looks safe from what I can see.

It not actually the tune itself (tune is ok) that the problem its the logging, the OFT is either asking for the wrong info from the ecu or scaling this info incorrectly. The oft has to be set to recognise each different rom calid and ask for correct info, looks like on some roms is asking for incorrect info from ecu.

email the oft guys and show them the problems in the logs

correct i think the logging is bogus, the flkc does not match kc learned changes and other stuff is suspect, no it not normal

You should generally ignore FBKC anyway.
