NN tuning help

[RedShark_JK]

You change the inj fuel mass to trim the fueling with NN on.
Basically these tables tell the PCM how much fuel mass to expect at a certain PW.
If you make the mass smaller, it assumes the injectors are smaller and will command more PW to meet the target FA.
Obviously vise versa if you make the mass numbers larger.
So smaller fuel mass = richer AFR
Larger fuel mass = leaner AFR
Both Inj tables need to be same values

will it be same effect to reduce injectors PW instead of increasing mass ?

no you only need to change PW for range, only change mass for adjusting fueling

I love to break all the rules it seems...
Tuning with NN on, I set-up PE as an adder above stoich for my required AFR target.
Then I tweak fuel mass till that target is achieved.
So now if I make changes to PE, actual AFR pretty well follows what I command.
I thought this was common practice no?? Or is everyone still doing the DS NN thing of screwing the PE way up/down to get fuelling kinda correct at WOT??
I often add extra break points for Inj Ms also to get it real nice.

Do you mean that you change the labels on the injector PW table? Here are the values from my labels:
0.0
1.2
2.6
3.0
3.6
4.1
4.7
5.3
6.3
7.6
9.8
14.2
350.9
687.4
1,024.0

So does this mean you make the three bottom labels much.. much... much less smaller? Then log for it and make the appropriate changes via multiply special % ? Half or regular?? @HEMITUNA
