I'll second that one
An observation.
I saw a guy start a 7 one day. It was a hot start and he used the full throttle method. He wasnt fast enough a bring the throttle back as it fired and from the sound of it it reached at least 2000RPM in about 2 seconds. The tail went way up, the prop went way down, how it didnt dig into the ground is beyond me. Scared him and everyone else who saw it. He quickly changed his method to mixture lean and throttle just cracked. I cant understand why anyone would start with full throttle when the other method works so well. Dont know about you but I only have two hands and one is on the start button.
I was standing a bit too close to an aircraft when the fella used the above mentioned procedure once. He almost did a 180 into the ship parked next to him before he get 'er under control. I do not care to see that again!
The full throttle method, in conjunction with an MT or Whirlwind prop, is a recipe for disaster. These props are very light, and allow max RPM to develop quickly -- possibly before you could get the throttle back -- with potential spectacular results. Not good!
I urge you (ALL of you) to practice until you can do the 1/4 throttle (~1200RPM) procedure -- it is a far safer method for you, your wallet, and others around you. The Lycs start easy enough in ICO, after a bit of prime @ FT/full rich (1-2 seconds at most -- you will hear the pressure rise, indicating that the system is purged. Stop the pump at this point - try to NOT flood the engine).
Hot starting a TCM engine is a different art, generally done with the mixture full rich -- I am still learning that one. Ugh..
It may be that the new injection system from ECI behaves more like the TCM system, in which case those so equipped are warned against the Lyc procedures.
Additional item:
If your FI engine does not have a sniffle valve, GET ONE. Route the overflow out of the cowling with a hose or hard tubing.

Also, if it feels like Phoenix/Houston in August when you are doing this hot start, hit the boost pump switch once she's running to keep secondary vapor locking out of the loop. Adjust mixture as required for a smooth idle -- leaner is better in this case.
Carry on!
