Me? I'm going to have my say regardless, but Id be real, real curious as to why post that potentially help people and at a minimum spark friendly, insightful dialogue is being dismissed. If you find out, let me know. ;-)

[In response to people having 'theories' on temps and tuning']
I don't see it as a theory. Hmmm...the best way I can explain it is: some folks have their opinion on who won world war II." ;-) In other words, this is simple fact as I know it. Temps not only play zero role in an engines tune, I'll go as far as saying they can often be a liability. I could be wrong, and below is my experience and welcome this discussion for where I'm inept in any way.
Please don't misinterpret me here. I'm more than willing to engage in this, as I feel it is an important subject. I know spiderman or whatever is a popular subject ;-) but I'm here to talk RC.
The tempature of a nitro engine has nothing, zero, nada (you get the idea) with the tune of it, no more than the color of the engine.
Do you agree that an engine can be tuned at any temperature? If so, than think....how does that value play a role in the tuning process? At what point do you employ the temperature of an engine when analyzing whether it is tuned or not? In other words, agnostic of the temp, it is either tuned or not tuned.
Oh, trust me. I used to "believe" that the temperature was important for tuning. It's what I'd been told on forums such as this. However, here is what I found:
1. Temp guns are extremely inaccurate. Of course I went through meticulous calibration exercises (electric heat, boiling water, etc) and the result was always "this thing doesn't know what the true temperature is".
2. I own five different makes of temp guns. The variances are 7-20 degrees. Meaning that they are all at least 7 degrees difference with the two extremes having ~20 degree difference. To take it further while I have five makes, I have six temp guns. Two of them are the same "Lost Temp Tuner". They are 12 degrees apart in readings. Everything from a battery's current charge, to a finger smudge on the infra-lens will make all the difference in the world. Bottom line, I have found them to simply be inaccurate. If anyone thinks I should try some additional methods let me know. Certainly not saying it's impossible to obtain a true temperature of an engine, I'm saying based on my experience, it's extremely rare....
3. You noted 250-260 I think. I have engines that scream bloody murder at 225 and some at 295. This of course depends on when I take them and with which temp gun. Thus with temp guns being inaccurate, and all engines (even same make) being different, I fail to see the correlation between temp taken by a hobbyist and their analysis of a tune. I hope that makes sense. In other words, I'm trying to understand what correlation you even have with respect to the two.
However, let's assume someone chimes in with "here is what you need to do to get accurate temps", I say thank you, now we know the temp of the engine. And? The temp, at most, is the end result. Meaning that for it to become hot, it has to be lacking proper lubrication. BEFORE it gets "hot" it's in a lean condition...one that can be read *much more accurtately* than the temps. If you let it lean out, then the engine will get "hot". Ah....but what is hot? Certainly the method of tuning is not to let it lean out, take the temp, and then compare if that temp is close to the last time it leaned out, and if it is....and? If it isn't....and?
I had my epiphany on temp guns when we were at our lakehouse a few years ago, and I forgot all of them. One of my engines was relatively new, but I started thinking: everyone who'd always advised me to stay completely away from temp guns while tuning because they are agnostic of actual tune, well....their engines ripped. Much more so than those who feel it plays ANY sort of role. You see, to me, there is no "debating" it. There are no different theories. There is only fact as I know it. I own a stable of engines that get off pretty good and I've yet to take their temps. Prior I struggled to get them thumping like I'd wanted to.
Full disclosure: I don't even use temp guns when breaking in engines. I know it probably gets some of ya'll agitated but would ask you understand I've broken in a plethora of engines without them and many have 10+ gallons and are still rocking and rolling. Once again, facts. If you go back to my experience on accuracy, then it makes sense as a false reading during break in is much more dangerous than tuning....or good ol' common sense.
As stated, I did not want to hijack the other post where you replied, and do agree it's a great topic for any nitro rc forum. One thing I'm not, when it comes to this subject, is close-minded. Hell, if I was I doubt I would have ever ditched them. So, please by all means let me know what I'm missing here, or how a temperature plays any role in assuring a tuned engine. If you simply disagree, then no problem. Hopefully some folks new to the hobby at least got to read another viewpoint and decide for themselves. Thanks in advance for the great dialogue on this subject - all of you. I travel quite a bit so forgive lack of responses but again this is a great topic in my opinion.

On a positive note, i received the following from members (I don't even know) who did get to see it before it was taken down.

'This is a breath of fresh air. I can't say anything you are doing is incorrect, I can just say it's nice to see another viewpoint about this on here'
'Well put'
'This post has opened my eyes some. Thank you! Please post more.'
The last response made my day. That was the ONE person, I always hope get it. More the better, but as long is there is one....;-) Anyway, more to come on my vid,.
