FP3 tweaking the tunes

The Cranking fuel table usually benefits from being reduced 2 from top to bottom. Starts easier. The decel enleanment can be decreased by 0.2 if you have decel pop. If no decel pop increase it 0.2 until you get decel pop. Will get little better mileage if increased. The Accelerator Enrichment usually doesn't need any thing on stock exhaust and bike. If need can increase it by 0.1 from top to bottom. With a 2 in 1 you usually benefit from a richer mixture by 2 to 5 VE points then autotune. I have looked at the FP3 app on phone and maps look pretty good to start with. One thing to remember is if the change doesn't improve change it back. Try to only adjust one thing at a time, as you won't know for sure what did what. Don't be surprised if you can't tell a difference in VE table changes unless you go over 5% either way.
I've seen your old post and I've got a question for you: what is the cranking fuel table and where is it on the FP3?
Thanks in advance

That is IAC for warm up. Has nothing to do with Cranking fuel. It controls how much air the engine gets at different temps while warming up. It functions for about 2 minutes.
The Cranking fuel is under the Start up and Idle tab under the View/edit Maps tab. It is called Cranking fuel. If engine is stalling the starter, usually too rich lower the cranking fuel at that temp about 2 points. If you get it too low it will spin over and not want to start. If engine is making a really bad noise when trying to crank usually starter clutch. Sometimes can get away with reducing fuel and helping for a while. You can also just bump starter button and let engine roll back from running up on compression then hold button down and will crank easier. This stuff works for me. A new battery is also sometimes a good fix for hard to turn over engines.

I've solved the mystery: tabs are different for different models and years!
So, the tabs for my Softail Custom FXSTC 2010 don't include the cranking fuel tab!
I'm so upset...
Is there anything I can do?

Auch!
Sorry for bothering you....
So, taking a look at FP3 App in demo mode, that's what I've understood:
softail 2012 up ecu version 357 cranking fuel map
softail 2011 ecu version 241 no cranking fuel map
softail 2010 ecu version 176 no cranking fuel map
Am I screwed or there's something else I can try to have all the tabs in the app?
