No experience hot starting a Cirrus but I remember this article by an old flight instructor of mine.

In the 207 on one of my quick stops I turn on the AUX boost and push in the throttle until I start to get a fuel flow reading. Then turn off the pump, and pull the throttle to idle. Starts right up.

The Cirrus can be a pain in the ass when hot.
That is all.
Well, not quite...prime the • out of it with the mixture in idle cut off and throttle idle. Then mix rich, half second prime, half throttle, feet on the brakes and fire away.

If I ever have any trouble with the 207, I go throttle, mixture rich, give it a good two-three second shot of fuel pump, then mixture cutoff, then crank. As soon as it fires, mixture rich, then throttle back. Never has failed me. (Normally first start is 2-3s shot of fuel, mixture rich, throttle closed... subsequent starts are 0.25-0.5s shot, mixture rich, throttle closed)
Lots of airplanes are quirky due to installation differences, though. (Or other subtle differences)

And boost pump on after a few blades through if it hasn't fired up.
99% of the time it works every time.
I purge the fuel lines (mixture/throttle idle cutoff, low boost 30 seconds or so), open the throttle around 1/2 inch, mixture full rich, and crank. I turn on low boost as I start cranking. Pretty good success rates. I'm flying the TSIO-550E instead of the -K in the Cirrus but for all practical purposes they're about the same.
Somewhere during 600 hours in the things I "trial and errored " myself into using this technique. Mixture: full-rich, Throttle: somewhere up there :shrug:, and crank. As soon as I got a cough I'd use my throttle (pimp) hand to switch into low boost. Weird but it works.

I've only got around 1,000 hours in Cirri, and I have a technique that works every time for each bird in our fleet, from generation 2 through the brand new 5.
1. Mixture Idle/CutOff
2. Throttle full open
3. Boost Pump OFF
4. Begin cranking the engine.
5. While cranking, flip the boost pump on.
6. Mixture full rich and throttle back to about 1/4 once the engine turns over.
This procedure has never failed me on all 11 of our aircraft. It works every time, even in 100 degree heat with a very hot engine.

I once had an SR22 vapor lock so bad even the gascolator was dry. When the fuel pump just makes a smooth high-pitched whine, you're SOL...
For a hot start, push everything forward, pump to prime for 1 second (this will just purge the vapor), mixture idle cutoff, and crank. Absolutely minimal delay between prime and cranking the engine.
