CF is "correction factor" aka timing retard

just a quick heads up. i'm going to merge my nyet-20110825 with NLS / ALS and this M-box valentines day surprise. i'll update my XDF on the appropriate page and link it to here. will update linkage when finished.
tables will be set to default values and i'll provide exact suggestions on values people have been generally using.
more to follow...

I would like to thank all the members here for the on going research. Really, this is an immense help. Going to try to test this out tonight.

Also, can someone assist with the correct tunerpro screenshots to add the table KFLAMKR? That still seems to be missing. Julex can you get screenshots of the actual KFLAMKR table values you are using? I know you already posted your KFLBTS and KFLAMKRL, as well as telling us that you are using LAMFA set to all 1.0.

KFLAMKR stays stock. It is a multiplier for KFLAMKRL table which allows you to fine tune response at whatever RPMs/Load point you want.

How is that possible? Unless my definition is wrong, KFLAMKR is mostly zeroes and values less than one. EDIT: FWIW my definition matches the specs that Tony posted.

dunno about that. The fact is that you can only shift from higher to lower load in an instant. The other way around takes time. However, even if true, you're assuming ECU is somehow lagging in its load calculations which if true, would ruin your engine many times over to date.
The ECU calculates load out of mainly MAF flow and then does some modeling as to how all that air behaves before it even reaches our cylinder. Injection time is also a real time calculation affair which is calculated by looking at air flow and tons of other variables including all the lambda paths. Simply there is no such thing like fueling "lag" which you're trying to use as an excuse to employ LAMFA.
I used LAMFA only for couple of days and not as main focus of fueling effort (only to pre-fuel the engine when testing KR feling), like you are trying to, and I believe that I could not really use it properly as that map seemed to fall victim of multi-point interpolation where I wasn't getting as low of a Lambda as I wanted in my table but something higher slowly falling with time spent at the driver's requested load level. Many maps don't use absolute values at a given point of table but are interpolated and mean weighted with the adjacent points so if your LAMFA falls to say 0.75 at 100%, it won't immediately dump 0.75 value into Lambda path once you hit 100% driver load but will actually lag and gradually approach the 0.75 you want. But it might take a while.
Again, that was my observation, I believe, but maybe I am all wrong about LAMFA after all. It just has no use anymore with "0.00" knock path in KR lambda
Why not adjust axis making the 2 nodes around your desired transition point very close to each other? e.g. if you to go from 1 to .75 AFR after 80% load make axis RL -> .... 40 50 60 70 80 82 100 1 1 1 1 1 .75 .75 Assuming the axis is not used for any other map.

Just to add to this... I recently looked into an AWP (1.8T) ECU where I noticed this method was NOT used for fueling. Just food for thought, looks like BTS is the way fueling is done in that ECU. Not saying one way is wrong/right... just there is always more then one way to skin the cat

Thanks Julex. I have the same address. I'll have to double check my conversion and major order when I get home.

I have the same settings with much different results. Screenshots below are the same in both versions of M box that I have.

I apologize, I must have inherited this from tony's tune. You're right, stock S4 KFLAMKR is useless and needs to be altered. FWIW RS4 KFLAMKR is 1.0 in all cell.
