Guide Request: Speed Density Starting Fuel

[Water]

Would anyone be so kind enough to share how they approach starting and idle fuel for speed density based calibrations?

Background to why I’m asking:
I’ve made a custom turbo kit. 1,000cc injectors, dw65c. Gt3076. Nothing radical, on a stock k24z7, original engine in vehicle.

I’ve already dialed in an AFM based calibration while the engine had 1,000 cc injectors, stock intake, no turbo. Then set my cruising AFR to 15, just to explore a few slight changes and analyze if this helps fuel economy (it did slightly), and overall “research” purposes. My cats are fine too.

But when researching and comparing speed density calibrations for similar setups, I could not understand the proper method of approach. If I got it to fire, it would immediately shut off after about two seconds.

This isn’t a mechanical or electrical issue - when I upload the previous AFM calibration I made, it starts and idles just fine.

So I’m kindly asking any expert to chime in so any lurkers like myself can have a more in depth understanding of this procedure as the hondata help tab is rather vague for the novice tuner.

Also, I do plan on getting a professional dyno tune, but I’d like to know exactly what’s happening while it’s happening.

If possible, follow a what changes and why format for each calibration setting relevant to this phase of tuning. A lot of other forums just mention overall trim and cranking trim without a solid explanation of how these settings affect the engine mechanically/physically with respect to time (for startup).
