Ok thanks for checking back in on this. The description on this one is very thorough and reads like it’s exactly what I need but I really don’t think it’s doing anything to help. I’ll keep at it and see if I can figure something out

I was able to drive it a bit yesterday and unfortunately it doesnt seem anything I have tried has helped.
The thing I am confused on is if its going into DFSO should the lambses continue to ramp rich? It seems like this is counterintuitive of the point of DFSO which is fuel savings. I decel'd and downshifted from 4th to 2nd coming to a light yesterday and the lambses ramped all the way to .75 and when I clutched in it started to surge pretty bad, and I am pretty sure the lambses were stuck there while the surging continued.

in dfso it will be in open loop so it wont ramp at all
for now your best bet is to set fn338 to force open loop on decel at those rpms and then you can very easily dial in the decel correction table
make sure the decel table is set to be used at closed throttle at wot only.

Is 1035 in gfux the equivalent to 1052 in cbaza?

No. FN1035 is the airmass correction. Doesn't exist in cbaza.
FN1052 is the transient fuel manifold volume correction. Doesn't exist in gufx.

I'm not 100% sure how to setup fn338, does this look ok?
Looking into this more did I go the wrong way with load? Found where this is touched on in the write-ups and it reads that the load should be higher so OL is for below that load. I am also not sure if there is a reason to have different loads at different rpms? I think I want it to go into OL all the time on decel which is why I put the same load in all columns.
I am not sure on how to verify if the decel table is set for CT and WOT only. I am using the latest files so is it setup that way to start or is there something that needs to be changed to make this happen?
