Is it maybe possible that the startup procedure is incorrect?

Hi all. After much thinking in the shower, I figured out how to implement this in about six lines of code. Of course this spawned several hours of other code edits, adding more Lycoming behavior, and testing, but it was still easier than I expected.
This had the byproduct of allowing me to implement the delay between mixture cutoff and engine shutdown that many have been asking about for a long time.
It's surprisingly easy, so long as everyone is okay adopting the mixture control bindings of my turbocharged aircraft. (It works with the native bindings, so I'm not sure why people continue to struggle occasionally.) If they revolt, I will send them your way
Kidding, of course.EDIT: I cannot tell you how fun it is starting the engines this way that I am so familiar with from the real world

Kidding, of course.Nick, I should really know the answer considering I own just about every single one of your aircraft, but the native Mixture Axis/Mixture X Axis bindings map to the K events you need, yes? I don't think I've had any issues making use of them previously, but I haven't looked too closely at whether they're using K events or the A var you specifically say not to use.

@Black-Square That's awesome man!!! Looking forward to it!

@jasmits Sorry for the late reply to your question, i have talked with my Aircraft mechanic for you. You are actually 100% correct about the "why"! The Lycoming Bendix system is a continuous flow system, so it floods the engine immediately on "Rich" before the engine catches. Continental's system is engine-driven and RPM-dependent, which is why it doesn't flood during start. Spot on!

Must be a special kind of water supplied to your place!
Thank you, well done sir, appreciate your efforts massively! I just went ahead and bought the Commander, even though I'm still waiting for that Virpil yoke that seems to take forever to arrive on the market
-
@Black-Square is the Startup Procedure allready in the current version? i will wait to buy until its in.

maybe it will take a while
I'll probably be sending the new version to Just Flight later today.

@Black-Square wow, so amazing, i am now also owner of your commander, and yes, this is lycoming, perfect!! I have made my first test fly today and yes, this plane flies very easy and stable. i love the 70ties look, its so sexy this old thing. Now i need to startup her again to make more nautical miles with her. Thank you very much again. But sadly during a test flight, I lit a cigarette as typically for the 70ties, but unfortunately I found that the ashtray was stuck and wouldn’t open no matter how hard I tried. I had no choice but to throw the ashes and cigarette out the window, but don’t worry i don’t usually do things like that, but I had no other option. Maybe a very talented aircraft mechanic will be able to fix this someday. I think I’ll take the old lady to Nick, I’ve heard he’s the best there is.

I'm loving the new realistic start-up procedure on the Lycoming engine. I was completely unaware of this method because, IRL I've only flown behind Rotax & Continental engines. I genuinely feel like the Black Square Commander 114 is the most realistic & complete GA aircraft in MSFS24. Thank-you Nick.

Question on the priming procedure. The EFB outlines the procedure similar to starting the engine in that you start with the mixture cutoff, crack the throttle 1/4", turn on the fuel pump, then it says to increase mixture over 2-3 seconds. Fuel flow doesn't really seem to increase to the target value until mixture more on the rich side, so I wait until I achieve the target flow then keep the pump on for a few seconds before shutting off. Is that correct, more specifically, in that you ramp up the fuel mix from cutoff with pump on during priming? The priming procedure leaves you with the mixture full rich, so I then cut it back off prior to cranking the engine during startup.
