looking for another oil cooler

One example is my business partners m5 that lowers the revlimiter until the oil temp is warm enough or when too hot.

I don't really need you to believe me... But for you to argue it, you are using your own assumptions to debate proven facts that have been tested. I called uprev again yesterday about some stuff with my car and again verified with Rich there. Aside from him, I personally speak to most reputable VQ tuners on a regular basis for work, and have touched on the topic several times.

If you don't want to believe me, simply pick up your phone and call one of a dozen guys that know better.

If the 10-15 HP you're losing isnt worth a phone call to verify and small investment in better cooling, that's fine... If you don't want help from people who know, suit yourself.

Those parameters and their purpose will vary from one vehicle to another. As for your car and your data... Enjoy it, I don't really take it as any worthwhile information. I will rather take the word of industry professionals who have said so, and my own experiences that also prove it.

If you think you have nothing to gain by cooling your oil, than go ahead and run it as hot as you like. There's nothing left to debate. I hear you clearly that you don't wish to believe it, that's just fine with me. Carry on, there isn't anything left to say about it.
