Has decreased power output ever been verified on a dyno as oil temp. rises?

You'd think by now someone would have done this (especially oil cooler kit vendors???) and posted the results in order to verify or dismiss the rumors about the ECU decreasing the power output.

The ECU doesn't really "decrease" the engine output power. But yes, the lower the temperature that the engine is running (to a point), the higher the horse power (output). I know with my dyno results, they are probably a little skewed to the high side. I didn't realize at the time; that I should have closed the hood and not let the heat escape while doing my pulls.
